LG Dryer Not Heating: The Part It Usually Is, What It Costs, and When to Stop

6 LG dryer repair files · 123 community comments · 143 LG dryers in our catalogue · LG's own troubleshooting read in full

Turn off Energy Saver and reset the breaker before you buy anything: LG's Cotton/Normal cycle air-dries without heat for most of its length by default, and an electric LG on one leg of its 240 V breaker will tumble cold all day. If the dryer still runs without heat, the fault is in the safety chain, a thermal fuse (sold in a kit with the high-limit thermostat) that opens into a blocked vent, or in the heater itself: the element on an electric, the igniter and valve coils on a gas. Test the chain first, because it is a two-minute continuity check and the cheap part; most guides do, and the ones that start at the element end up there anyway. The one LG-specific cost is access: on the design iFixit's guide describes, the drum comes out before you reach the heater, and that is where a technician's minimum charge, not the part, decides fix or replace.

    LG's own checks

    Energy Saver · breaker · installation test InS → End · hose behind the dryer

    LG's page starts at airflow: run the installation test (InS, then End or 0 when clear), check the exhaust hose is not crushed, and turn off Energy Saver, which is on by default on Cotton/Normal. None of it costs anything.

    The checks, in order ↓
  2. Electric: runs, no heat

    Thermal fuse and high-limit, then the element

    fuse kit · element · thermistor

    Breaker fully off and on first: one tripped leg runs the drum on 120 V and starves the heater. Then the fuse and high-limit by continuity (they ship as a kit), then the element by the numbers, 20/40/20 Ω on iFixit's LG guide.

  3. Gas: runs, no heat

    Igniter, then the valve coils

    hi-limit reset $0 · igniter · gas valve assembly

    Power off, exhaust duct off the back: on the gas models howtofixit describes, the hi-limit behind that opening has a black reset button; press it, for free. Then lights off, watch the burner slot. No glow is the igniter once the fuse tests good; glow without flame is the valve coils (a coil at zero resistance will not open the valve, per howtofixit) or the flame sensor. Close the gas valve before opening anything.

01 / What this page adds

Seven numbers from the record

Three come from sources we read and link; four are computed from our own files, which are downloadable at the end of the page.

  1. 20 / 40 Ω

    iFixit's LG guide gives the heating-element readings by wire pair, red-to-blue about 20 Ω, blue-to-yellow about 40 Ω, red-to-yellow about 20 Ω, and a thermistor at about 11,000 Ω at room temperature. Those two numbers separate a dead element from a dead sensor before you buy either. 2

    iFixit, How to Troubleshoot an LG Dryer That Won't Heat (Ben Schlichter). The guide is written for the front-teardown platform: top panel, control interface, door harnesses, bulkhead and drum come off before the heater canister is reached, which is the design an owner on thecooldown.com complains about. homeessentialsguide gives 8–15 Ω for the element instead; the two are not reconciled by either source, so test against your model's tech sheet.

  2. InS → End

    LG's own first check is airflow, not the heater: the installation test runs the dryer empty and the display should return to InS after a minute and read End or 0 after the second; anything else is a restriction between the dryer and the outside wall. 1

    LG Help Library, Why is My Dryer Not Heating, Not Drying or Taking a Long Time. The same page says Energy Saver is on by default for the Cotton/Normal cycle and that the cycle air-dries without heat for most of its length, which is the single most common not-a-fault on this page.

  3. 4 of 5

    The thermal fuse is a no-heat candidate on 4 of the 5 LG dryer files in our corpus that carry the symptom, the heating element on 3, the high-limit thermostat on 1. One part number, 6931EL3003D, covers the fuse on four of the six files. 14

    Our repair corpus: six LG electric-dryer model files (DLE0442W, DLE2514W, DLE2515S, DLE5955W, DLEX3700W, DLEX4000B) built from vendor repair videos and parts catalogues; DLE5955W carries no no-heat entry. In LG's electric-dryer failure profile in our data the thermal fuse takes 32.2% and the heating element 32.5% of repair-video attention (the any-brand electric profile gives the same figures, so this is not LG-specific). Attention share, not a failure rate.

  4. 17%

    17% of 123 Reddit comments about LG dryers raise the thermal fuse or cutoff; 14% the heating element; 37% the vent, lint or airflow; 14% the breaker or 240 V supply.

    Counted over comments and posts in threads whose title names an LG dryer, or that name LG and a dryer term themselves, from 427 harvested threads. Keyword themes; a comment can match several. Method and limits in the field-reports section.

  5. Mostly cheap

    The parts that stop an LG dryer heating run from a cheap thermostat (the cheapest in the chain) to the costly gas valve assembly 5221EL2002A, on Amazon by part number; the thermal fuse 6931EL3003D is sold in a kit with the high-limit thermostat. The electric heater element 5301EL1001J comes as a compatible part or as a much costlier genuine LG part. 16

    Amazon Creators API search on the part numbers in our six LG files and the two gas numbers howtofixit names, lowest listing whose title carries the number; genuine and compatible separated in the decode table. Only howtofixit names any LG part number among the pages that rank for the query, and it prices none of them.

  6. 2.0%

    Yale Appliance's 2022 dryer report put LG at a 2.0% first-year service rate, second of the four full-size brands it carried (Whirlpool 0.4%, GE 5.2%, Maytag 6.0%) and under the 3.5% dryer average. Prudent Reviews' 2026 survey of sixteen repair professionals splits on the brand: two recommend it (one of them naming LG and GE as the brands with the fewest service issues), one tells customers to stay away from LG and Samsung. 10

    Yale Appliance, Most Reliable Full-Size Clothes Dryer Brands for 2022 (service calls December 2020 to October 2021); Prudent Reviews, The Most Reliable Washer and Dryer Brands (Andrew Palermo, updated 2026-04-29). Consumer Reports' 2026 survey of 96,315 dryers says LG accounts for more than half of the dryers its members bought in 2025. The one CPSC recall on LG dryers (2012, about 21,000 gas units) was a valve that would not shut off, the opposite fault; there is no recall for an LG that will not heat.

  7. $114 vs $25

    The median LG dryer in our catalogue costs $114.30 a year to run; LG's heat-pump DLHC1455 costs $25.04 a year to run. That $89-a-year gap is the only number that ever makes replacing a dryer over a cheap fuse arithmetic instead of impatience. 15

    annual_cost_usd on 217 LG dryer records (143 published) at the catalogue's EIA national residential rate; the cheapest-to-run published LG is the DLHC1455 at $25.04.

Left: which parts the 6 LG dryer repair files in our corpus list as no-heat candidates. Right: what the community's LG-dryer comments talk about when a dryer stops heating. The repair files rank the parts; the community count puts the vent first among the causes, because a no-heat thread on Reddit is where people go before they buy anything.

The corpus counts what a model's repair videos and parts lists cover; the community count is what people write about, and on these threads that is the vent first and the part second.

03 / Which cause

The causes, in the order to check them, with the part

Free checks first, then the safety chain (thermal fuse, thermal cutoff, high-limit), then the heater itself. Electric and gas dryers share everything up to the heater: an electric dryer heats with a coil, a gas dryer with an igniter, a valve and a flame sensor. Every part below is matched by part number; where no LG number is sourced, the row says so.

CauseWhat you noticeThe checkPart
Power, settings, vent (both fuels) Drum turns; clothes come out cold or take two cycles; or Energy Saver is on.LG: run the installation test (display InS, then End or 0); Energy Saver on Cotton/Normal air-dries without heat for most of the cycle; check the exhaust hose is not crushed or kinked. Electric: an LG on one leg of its 240 V breaker will tumble and not heat, so reset the breaker fully off and on and, if you own a meter, read about 240 V across the two hot terminals and about 120 V from each to neutral at the terminal block.$0
Thermal fuse or thermal cutoff Runs, no heat at all, after a hot or lint-choked cycle.Unplug. Behind the back covers on the design howtofixit describes, on the heater or blower housing; continuity across the two terminals, near 0 Ω good, OL blown. Never bypass it. Clean the vent before fitting the new one or it blows again.6931EL3003D (kit with 6931EL3001F)
Gas: resettable hi-limit tripped Gas dryer, runs, no heat, usually after a hot or lint-choked cycle.Power off, exhaust duct off the back; howtofixit: the hi-limit visible through that opening has a black button, press it. If it trips again, the vent is blocked.$0
High-limit thermostat Heats, then quits mid-cycle, or no heat with a good fuse.Same housing, same continuity test at room temperature. On LG the high-limit often ships in the kit with the fuse; fit both.6931EL3001F · blower thermostat 6931EL3002M
Heating element (electric) Fuse and thermostats pass, still no heat; sometimes a burnt smell or a visibly broken coil.iFixit: red-to-blue about 20 Ω, blue-to-yellow about 40 Ω, red-to-yellow about 20 Ω, and no continuity from any terminal to the canister (a short to ground). homeessentialsguide says 8–15 Ω; use your tech sheet. On the design iFixit's guide describes, the canister is reached from the front after the drum comes out; on the design howtofixit describes, from behind the back covers.5301EL1001J (the genuine LG part costs much more)
Thermistor Heat is wrong rather than absent: too cool, too hot, cycles end early, or a temperature code.About 11,000 Ω at room temperature per iFixit; a reading that does not fall as the sensor warms is the failure. Cheap; test before the board.6323EL2001B
Gas: igniter Gas dryer, drum turns, igniter never glows (look through the burner inspection slot with the lights off).howtofixit names the LG igniter 5318EL3001A; iFixit's generic gas guide expects 80–400 Ω across a good igniter. No glow with continuity on the fuse chain means the igniter or its circuit.5318EL3001A
Gas: valve coils and flame sensor Igniter glows, no flame; or glows, lights, and goes out.howtofixit: check continuity on both coils; a coil reading zero means the gas valve will not open. iFixit's generic gas guide: glowing for five minutes with no flame is the flame sensor; glowing up to two minutes then quitting is the coils (500–1,500 Ω). The coils are DIY; the valve body is the gas fitter's.5221EL2002A valve assembly
Control board Every part above tests good and 240 V reaches the board.howtofixit's last step: 240 V AC at the board between the red and black wires with everything else good. A technician's diagnosis; our DLEX4000B file carries the board as EBR31002601, a costly part.technician

LG dryer runs but no heat: why the drum still turns

An LG dryer's motor runs on 120 V; only the heater uses the second leg of the 240 V supply, so a tripped half of the breaker, a burnt terminal or a bad cord leaves the drum turning and the air cold. Downstream of the supply the heat runs through a chain of safeties in series, thermal fuse, thermal cutoff, high-limit thermostat, and any one of them open cuts the heater and nothing else. The heater itself fails last and loudest: an element coil breaks (reads OL) or touches the canister (reads to ground); a gas igniter cracks and never glows; a valve coil opens and the burner never lights. Every guide on this page follows that chain because the dryer's own design does.

If your LG dryer is taking too long to dry your clothes or your dryer is not heating properly this is likely due to a blockage to the dryer's airflow, which will make dry times longer than normal. 1

04 / By symptom

What you see, and what it usually is

Match the symptom, not the part. Each row names the parts in the order the guides and the community check them.

  • Not a fault Cotton/Normal cycle, clothes barely warm, dryer otherwise fine — Energy Saver. LG's page: it is on by default for Cotton/Normal and the cycle air-dries without heat for most of its length. Turn it off before you buy anything. 1
  • Not a fault Takes forever, display shows d80, d85, d90, d95 or Flow Sense bars — Airflow. LG's installation test (InS, then End or 0) tells you whether the restriction is between the dryer and the wall; a crushed hose behind the machine is the usual cause. The heater is fine. 1
  • DIY first, then a technician Electric, drum turns, stone cold, nothing else wrong — The breaker first: one leg of a two-pole 240 V breaker can trip and leave the motor running on 120 V. Reset it fully off and on. If it trips again, or the terminal block reads 120 V on one side, that is an electrician, not a part. 2
  • DIY part Electric, drum turns, stone cold, breaker fine — The safety chain, then the heater: thermal fuse 6931EL3003D (with the high-limit in the kit), then the element 5301EL1001J. Four of our six LG files list the fuse; three the element. Continuity on the fuse, 20/40/20 Ω on the element. 14
  • DIY part Heats, then stops heating partway; or heats on some cycles only — High-limit or blower thermostat tripping (6931EL3001F, 6931EL3002M, both cheap parts), or a thermistor reading wrong (6323EL2001B). Clean the vent as well, because an overheating dryer is usually a choked dryer. 14
  • DIY part Gas, igniter never glows — Igniter 5318EL3001A once the fuse chain tests good; iFixit's generic figure for a good igniter is 80–400 Ω. 5
  • DIY first, then a technician Gas, igniter glows but no flame, or flame dies — Valve coils (a coil at zero resistance will not open the valve, per howtofixit) or the flame sensor. The coils are a DIY swap; if the valve body itself is suspect, or you smell gas, close the supply and call a technician. 5221EL2002A is the full assembly, the costliest part here. 5

By what the display shows

InS, then End or 0
LG's installation test result: End or 0 means the airflow is clear. Anything else, the restriction is between the dryer and the outside wall. 1
d80, d85, d90, d95, Flow Sense
LG's airflow warnings, named together on the not-heating page; the number is the degree of restriction. Clean the duct and the wall cap, check the hose behind the dryer for a kink. Not a heater fault. 1
A temperature or sensor code (TE1 on every one of our six files)
Test the thermistor (about 11,000 Ω at room temperature per iFixit) before the board; it is one of the cheapest parts on the page. 2
Nothing at all, drum turns
None of our six LG files carries a code for a blown fuse or a dead element. Unplug and go to the safety chain. 14

05 / The routine

Diagnose in this order

Free checks, then the safety chain with a multimeter, then the heater, then stop. Unplug before opening any panel; on a gas dryer close the gas valve too. Reconnecting a bypassed thermal fuse is how dryers catch fire, so never run one without it.

  1. Minute 0 Settings and the breaker. Energy Saver off. Cycle set to a heated dry, not Air Dry. Breaker fully off, then on: on an electric LG a half-tripped two-pole breaker runs the drum and not the heater.
  2. Minute 5 LG's installation test. Empty, cool drum; run the test from the panel; the display should come back to InS after a minute and End or 0 after the second. Check the hose behind the dryer is not crushed. Clean the lint screen and the wall cap.
  3. Minute 20 Unplug. Meter on the terminal block (electric). About 120 V from each hot to neutral and about 240 V across the two, per iFixit. 120 V on one side is the supply, not the dryer.
  4. Hour 1 The safety chain. Back covers off (howtofixit's route). Thermal fuse and high-limit thermostat on the heater or blower housing: continuity across each, near 0 Ω good, OL blown. Replace as a pair (6931EL3003D ships with 6931EL3001F) and clean the vent, because a fuse that blew once will blow again into a blocked duct.
  5. Hour 2 The heater itself. Electric: element pairs at about 20, 40 and 20 Ω (iFixit), no continuity to the canister; on the design iFixit describes the drum comes out first. Gas: watch the igniter through the burner slot; no glow is the igniter (80–400 Ω), glow without flame is the coils or the flame sensor.
  6. Stop Board, motor circuit, or a gas valve body. If 240 V reaches the board and everything downstream tests good, the heater relay on the board is the last suspect and a technician's call; so is any gas valve work beyond the coils. A repair company's fee schedule in this harvest starts at an $89 service call and a $185 minimum labor charge.
The tell that it is the vent, not the heater A thermal fuse that blew is a thermometer: it opened because the air stopped moving and the heater box got hotter than it should. If the new fuse lasts a week, you replaced the fuse and not the cause. LG's installation test and a look at the hose behind the machine come before the meter for that reason. 1

06 / What to expect

What it costs: fix or replace

The repair steps against the two numbers that decide it: what the dryer you have costs to run (our catalogue's median LG is $114.30 a year) and what a replacement costs to run (LG's heat-pump DLHC1455, at $25.04 a year).

  1. $0 Energy Saver off, breaker reset, vent cleared. LG's own page starts and ends here. If the installation test passes and the dryer heats, it was never broken. 1
  2. Low cost Thermal fuse, high-limit, blower thermostat, thermistor. Every sensor and safety in the chain is a low-cost compatible part, and the fuse comes with the high-limit in the kit. The genuine LG high-limit costs more. Against any replacement dryer none of these is a decision. 16
  3. Mid cost Igniter (gas) or heater element (electric). Element 5301EL1001J, compatible or the much costlier genuine part; igniter 5318EL3001A. howtofixit's only price is for the multimeter; on the front-teardown design iFixit describes the cost is the labor, which is why the owner on thecooldown calls the design out. 5
  4. Highest cost Gas valve assembly. 5221EL2002A if both coils test bad or the body is suspect; the coils alone are the usual fix and the valve body is a gas fitter's job. A repair company in the harvest lists an $89 service call and a $185 minimum labor charge before parts. 8
  5. $114/yr What the dryer you have costs to run. The median LG electric dryer in our catalogue costs $114.30 a year at the national rate (gas dryers carry no running cost in the catalogue). A cheap fuse buys another year of that at little cost; a board or a motor on a fifteen-year-old vented dryer is where the next row starts to matter. 15
  6. Replace Replace with a heat pump and keep the difference. LG's DLHC1455 heat-pump dryer (a 4.2 cu ft compact) runs $25.04 a year, $89 less than the median LG. That is a long payback on electricity alone, so it is a reason to choose a heat pump when the dryer is dead, not a reason to kill it. The cheapest-to-run published LG is the DLHC1455 at $25.04 a year. 15
The rule we could not source The 50% rule (replace when the repair costs half the price of a new unit) appears on many pages and on none with an origin. On a dryer the parts are so cheap that the rule almost never bites: the decision is age and access. A thermal fuse on a fifteen-year-old dryer is still a ten-dollar fix; a control board or a motor on the same dryer is where replacement, and the heat-pump running-cost saving, start to win.

07 / The parts

6 parts, one per fault

We did not fit these parts; see the method note.

Each part is the one the corpus files, the guides and the community name for that fault, matched to Amazon listings by part number. The pick is the lowest-priced listing that names the part number.

  1. Runs, no heat at all

    Thermal fuse kit 6931EL3003D

    6931EL3003D · back covers · continuity

    The first part most guides test and the cheapest link in the chain; it opens when the air stops moving. The listing ships the fuse with the high-limit thermostat 6931EL3001F, and 6931EL3003D is the number on 4 of our six LG files (DLE0442W, DLE2514W, DLE2515S, DLEX4000B) and the one howtofixit names.

    A blown fuse is a symptom of a blocked vent; clean the duct before you fit it or it blows again. Never run the dryer with the fuse bridged.

  2. Chain tests good, still cold (electric)

    Heating element assembly 5301EL1001J

    5301EL1001J · multimeter

    The heater canister on 3 of our files (DLE2515S, DLEX3700W, DLEX4000B) and the number howtofixit names. iFixit's readings by wire pair: about 20, 40 and 20 Ω; OL on any pair or continuity to the canister is dead.

    On the design iFixit describes the drum comes out before you reach it; on the design howtofixit describes it is behind the back covers.

  3. Heats, then quits; or no heat with a good fuse

    High-limit thermostat 6931EL3001F

    6931EL3001F · continuity

    The thermostat that cuts the heater when the box overheats and resets when it cools; the same housing as the fuse and usually in the same kit. On our DLEX4000B file.

    If it trips repeatedly, the cause is airflow, not the thermostat. The blower thermostat 6931EL3002M is in the decode table.

  4. Wrong heat, or a temperature code

    Thermistor 6323EL2001B

    The temperature sensor the board reads, on 5 of our six LG files (DLE0442W, DLE2514W, DLE2515S, DLE5955W, DLEX4000B). iFixit: about 11,000 Ω at room temperature; a reading that does not fall as it warms is the failure. The cheapest part on the page and the one to rule out before a board.

    Genuine listing: none found under the rule in the decode note. Test it in place with the wires off; do not replace it for a fuse fault.

    5318EL3001A · gas valve closed

    The part howtofixit names for an LG gas dryer whose igniter never glows once the fuse chain tests good; iFixit's generic figure for a good igniter is 80–400 Ω. Not in our files, which are all electric models.

    Handle it by the base; the element is brittle. Close the gas supply before opening the burner.

    The full burner valve howtofixit names; a coil at zero resistance will not open it. The coils alone are the usual fix and a DIY swap; the body is the gas fitter's. Not in our files, which are all electric models.

    Genuine listing: none found under the rule in the decode note. If you smell gas, close the supply and stop. This is the one part on the page we would not fit ourselves.

  • Maker If your LG dryer is taking too long to dry your clothes or your dryer is not heating properly this is likely due to a blockage to the dryer's airflow, which will make dry times longer than normal. 1
What to do with that Find out how your model is put together before you order anything (the service sheet is usually taped inside the lower front panel). Two back covers off is a Saturday morning; the front teardown iFixit describes is an afternoon and a helper, and it is the reason a low-cost element on an LG can cost a technician's $185 minimum. LG's warranty terms were not reachable from its site in this pass, so we do not state them; the recall does not cover a dryer that will not heat.

09 / The decode

The no-heat parts, by part number

Amazon Creators API, 2026-09-13. Genuine = the listing title begins with LG or says Genuine or OEM, and does not say compatible, replacement for, direct replacement, OEM replacement, upgraded, premium, with upgrade, OEM-quality, OEM standard, OEM Mania, OEM produced or fit(s) for; everything else is listed as compatible. A third-party listing that leads with the brand name can pass this rule, so the ASIN and title are in the download.

7 part numbers from our LG dryer repair files and the guides we read, searched on Amazon by number. The table shows each part number, its fault, and which corpus model files carry the part.

  • 5 of 7 part numbers have a listing that passes the genuine rule; all 7 have a compatible listing.
  • The whole safety chain (thermal fuse, high-limit, blower thermostat, thermistor) is made of low-cost compatible parts, and the fuse listing ships with the high-limit. The costlier parts are the element, the igniter and the gas valve assembly.
  • 6931EL3003D is the fuse number on four of our six model files (DLE0442W, DLE2514W, DLE2515S, DLEX4000B) and the one howtofixit names; 5301EL1001J is the element on three (DLE2515S, DLEX3700W, DLEX4000B). The two gas numbers come from howtofixit only and are in none of our files, which are all electric models.
  • The moisture-sensor and drum parts in the corpus are not in this table because they do not stop a dryer heating. The DLEX4000B file carries the control board as EBR31002601; it is left out because it is a technician's diagnosis, not a continuity test, and it is a costly part, so the fix-or-replace section is the place for it.

What thirteen sources say, and where they split

1 manufacturer page · 1 repair wiki · 5 competing guides · 1 owner story · 2 reliability reports · 1 regulator · 1 repair corpus · 1 community harvest — every row links to the page it came from.

LG's own help page, iFixit's LG guide, the six competing pages that rank for the query on Bing (#3 to #9 when we checked on 2026-09-13; LG holds #1 and #6 and iFixit #2), two reliability sources, the CPSC record, our own repair corpus and the community harvest. Nine give an order of checks; four do not.

Where they agree

  • Power and airflow before parts. LG, iFixit, homeessentialsguide and lgparts all put the breaker, the settings and the vent ahead of any component, and LG's installation test settles the airflow question in two minutes.
  • The thermal fuse is the first part. Every guide that reaches the parts stage lists it first or second, howtofixit and our corpus agree on the number (6931EL3003D), and it is a cheap part.
  • Continuity is the test. Fuse, thermostats and element are all checked the same way with a multimeter; iFixit and homeessentialsguide are the only sources that put numbers on the readings, and they disagree on the element.
  • No source gives a failure rate for this fault. Yale's 2.0% is a first-year service rate across all faults on 2021 sales; Consumer Reports' 4% is heating-element trouble across all electric dryers; our corpus counts repair-video attention. The page uses each for what it is.

Where they split

  • Fuse first, or element first? — howtofixit, hillcountryrepairs, our corpus and homeessentialsguide: the thermal fuse. smartapplianceservices and iFixit: the element, once power is proven. The community: the fuse, because it is the part people actually replace. Test order is the answer, not part order: the fuse is a two-minute continuity check on the way to the element, and on four of our six LG files the same cheap kit covers the fuse and the high-limit. Buy the element only after the element reads open.
  • What should the element read? — iFixit's LG guide: about 20, 40 and 20 Ω by wire pair. homeessentialsguide: 8 to 15 Ω. Neither cites the other or a tech sheet. LG elements are tapped coils, so the pair you measure changes the number; a reading of OL on any pair, or continuity to the canister, is the failure on every source. Use the tech sheet taped inside your dryer for the exact values.
  • How reliable is an LG dryer? — Yale's 2022 dryer report: 2.0%, second of four and under the 3.5% average. Prudent Reviews' professionals: two of sixteen recommend LG, one of them naming it with GE for the fewest service issues; one (Miller's Appliance Service) says LG and Samsung are two brands to stay away from. Consumer Reports: LG is more than half of what its members bought in 2025; no number outside the paywall. Good on the one hard series, and the series is four years old and from one dealer. Nothing in it says an LG is more likely to stop heating than another dryer; the LG-specific finding on this page is access, not failure.
  • Is an LG harder to fix than other dryers? — thecooldown's owner and iFixit's teardown sequence describe a dryer that needs the drum out to reach the heater. lgparts and howtofixit describe two back covers off. LG's own page never reaches the heater. None of them names the models each design applies to. Both are true for different LG dryers, and no source we read draws the line between them. Look at your own machine before ordering: the part is the same price either way; the labor is not.

What 123 LG dryer comments say

123 comments about an LG dryer · from 427 threads · r/appliancerepair, r/Appliances, r/HomeImprovement · Feb 2018 – Sep 2026

We harvested the top-voted threads for nine dryer-no-heat queries on r/appliancerepair, r/Appliances and r/HomeImprovement and kept every comment or post about an LG dryer (threads about other appliances, washer-dryer combos and heat-pump units excluded): 123 in all from 427 threads. The shares are the proportion of those comments that raise each theme; a comment can raise more than one. Each quote is a first-person comment from the LG set, chosen for fit within its theme; its score at harvest is shown, and the ranked candidates for every theme are in the download.

Share of comments about an LG dryer that raise each theme

  1. Vent, lint, airflow 37% · 46 comments

    “Horizontal, it goes (from the dryer) down a couple feet then takes a hard left for only about 12-15 feet then comes back up no more than a foot to the outside. I unfortunately do not have a leaf blower. When this guy comes back I hope he figures this out, i'm not paying almost $200 to have this not be fixed”

    The theme LG owners raise most, and LG's own first check: a duct run the owner walks through foot by foot, in a thread titled for a d90 Flow Sense warning.

  2. Repair or replace, cost 37% · 45 comments

    “I'd say invest in a new dryer. Replacing the heat element can be a DIY project if you're somewhat handy. Out of curiosity, do you have sensors on the inside of your drum (attached to the lint trap)?”

    The repair-or-replace question as an LG owner asked it, and the answer they got: the element is a DIY job for the handy, and a new dryer for everyone else.

  3. Gas: igniter, valve coils, flame sensor 21% · 26 comments

    “Does your igniter glow? Check continuity through the flame sensor. Part number 6501EL3001A If the igniter is glowing for a while and the circuit inside the sensor doesn’t close…. I think you know what to do.”

    For a gas LG, a commenter's first question is whether the igniter glows, then the flame sensor, and names its part number, 6501EL3001A, which none of the guides we read carries.

  4. Fixed it myself 16% · 20 comments

    “Once I fixed the igniter I got a flame and some heat but it quickly went out. Compared to before when there was no heat. I discovered my vents were extremely clogged up. Had to go on the roof with a leaf blower and blow everything down and out.”

    A fix in two parts: the igniter first, then the clogged vent that was the real fault, cleared from the roof with a leaf blower.

  5. Runs but no heat 20% · 24 comments

    “When I put my hand in to check if there is heat at all, there is no heat at all when it has been on for a few minutes.”

    The symptom as an owner checked it: a hand in the drum after a few minutes.

  6. Thermal fuse or thermal cutoff 17% · 21 comments

    “I'd start with checking the thermal fuse for continuity first. Done many of these! [...] It would allow it to start, but wouldn't heat. Could also easily be the ignitor too.”

    A commenter who has done many: continuity on the thermal fuse first, because it lets the dryer start and stops the heat.

  7. High-limit or cycling thermostat 20% · 24 comments

    “A bit late to the party, but I'd suspect the blower housing thermostat. If that trips, the display will look like it's doing its job, but it won't tumble or heat. If you check that for continuity, I'd bet it reads open. Clean your vent when you replace it or you'll be doing the repair again soon.”

    The blower-housing thermostat in one commenter's words: the display looks normal, the dryer will not tumble or heat, and the vent is why it tripped.

  8. Breaker, 240 V, half power 14% · 17 comments

    “Check voltage on the back where power cord is with a voltmeter should have 220-240 volts from L1 to L2 I then would test continuity on my thermostats with a voltmeter . If you replace everything and it works then goes out again shortly after (2-5 days) check your vent pipe for airflow”

    The supply check in first person: 220–240 V between L1 and L2 at the cord terminals before any part.

  9. Heating element 14% · 17 comments

    “LG dryer heating elements don’t fail, statistically. I’ve replace 1 in the last 11 years of full time appliance service. With that said, if it indeed has failed again… weird.”

    The counterpoint from a working technician: LG elements rarely fail, so an element that reads good is not the part.

  10. Technician, service call, warranty 15% · 19 comments

    “LG makes some of the highest rated most reliable washers and dryers on the market... I wouldn't listen to your repairman.”

    The brand argument in one line, from a commenter telling the poster not to trust the repairman's verdict on LG.

The parts the community names most

  1. Thermal fuse or cutoff 21 comments — 17% of the 123 comments
  2. Heating element 17 comments — 14%

Method. 427 threads gathered 2026-09-13 from r/appliancerepair (239), r/Appliances (159), r/HomeImprovement (29), through Reddit's public search, sorted by top and by relevance for nine dryer-no-heat queries (four of them brand-specific); Reddit blocked a share of thread fetches, so this is a sample of top-voted discussion and not a complete count. The unit of analysis is a comment or post in a thread whose title names an LG dryer, or that itself names LG and a dryer term (123 of 4,702 posts and comments harvested); AutoModerator and bot comments are excluded. Themes are keyword matches on the comment's text; a comment can match several. Quotes are trimmed for length and profanity; where a post rather than a comment is quoted, its title is shown before its body; nothing is reworded. Scores are Reddit upvotes at harvest time.

12 / Questions

Frequently asked

Why does my LG dryer run but not heat?
Because the motor and the heater are on different circuits. On an electric LG the drum runs on 120 V and the heater needs 240 V, so one tripped leg of the breaker leaves it tumbling cold; after that it is the safety chain (thermal fuse 6931EL3003D, with the high-limit in the kit) and then the element (5301EL1001J). On a gas LG it is the igniter or the valve coils. Check LG's Energy Saver setting first: it air-dries the Cotton/Normal cycle without heat for most of its length by design. 12
How do I run the LG dryer installation test, and what do InS and End mean?
With the drum cool and empty, start the test from the panel; LG's page says the display should return to InS after the first minute and read End or 0 after the second, which means the airflow is clear. Anything else means a restriction between the dryer and the outside wall: the hose behind the machine, the duct, or the wall cap. 1
How do I test the thermal fuse on an LG dryer?
Unplug it. On the design howtofixit describes the fuse is behind the two back covers on the heater or blower housing; pull both wires and read continuity across the terminals: near 0 Ω is good, OL is blown. Replace the fuse and the high-limit thermostat together (6931EL3003D ships with 6931EL3001F) and clean the vent, or the new fuse blows the same way. Never bridge a fuse to test the heater. 56
What should an LG dryer heating element read on a multimeter?
iFixit's LG guide: about 20 Ω red-to-blue, 40 Ω blue-to-yellow and 20 Ω red-to-yellow, and no continuity from any terminal to the metal canister. homeessentialsguide gives 8–15 Ω. The two do not reconcile; an open pair or a short to the canister is the failure on both, and the tech sheet inside your dryer has the exact figures. 26
My LG gas dryer's igniter glows but there is no flame. Which part?
The gas valve coils or the flame sensor. howtofixit: a coil that reads zero resistance will not open the valve. iFixit's generic gas guide: glowing for five minutes with no flame is the flame sensor; glowing for up to two minutes and quitting is the coils. If the igniter never glows it is the igniter (5318EL3001A) once the fuse chain tests good. Close the gas valve before any of it, and call a technician for the valve body. 53
How much does it cost to fix an LG dryer that is not heating?
The parts run from a cheap thermostat in the chain to the costly gas valve assembly, matched on Amazon by part number; the element comes as a compatible part or as a much costlier genuine LG part. One repair company in the harvest lists an $89 service call and a $185 minimum labor charge before parts; none of the ranking guides prices a repair. 168
Is it worth repairing an LG dryer?
For anything in the safety chain or the element, yes at any age: the parts are low-cost. The two things that change the answer are access (some LG designs need the drum out to reach the heater, per iFixit) and the running cost: the median LG dryer costs $114.30 a year to run and LG's heat-pump DLHC1455 about $25.04, so a dead motor or board on an old vented dryer is where replacement starts to pay. 152
Are LG dryers reliable?
Yale Appliance's 2022 report put LG at a 2.0% first-year service rate, second of the four full-size brands it carried (Whirlpool 0.4%, GE 5.2%, Maytag 6.0%) and under the 3.5% dryer average; no newer Yale dryer report was found. Prudent Reviews' sixteen repair professionals split in 2026: two recommend LG (one of them naming LG and GE as the brands with the fewest service issues), and one says LG and Samsung are brands to stay away from. Consumer Reports says LG is more than half of the dryers its members bought in 2025, without publishing a reliability number outside its paywall. 101112
Was there a recall on LG dryers?
One, in 2012: LG and Sears recalled about 21,000 gas dryers (DLG0452W, DLG1320W, DLG2051W and Kenmore Elite twins) because the gas valve could fail to shut off and keep heating after the cycle, with 141 complaints and three minor burns. It is the opposite of a no-heat fault, and a CPSC search on "lg dryer" returns no recall for one that will not heat. 13
Which LG part numbers fit my dryer?
From our six model files (DLE0442W, DLE2514W, DLE2515S, DLE5955W, DLEX3700W, DLEX4000B): thermal fuse 6931EL3003D, high-limit 6931EL3001F, blower thermostat 6931EL3002M, thermistor 6323EL2001B, heating element 5301EL1001J; from howtofixit for gas models, igniter 5318EL3001A and gas valve 5221EL2002A. Check the parts diagram for your model tag before ordering. 145
What do d80, d90 or Flow Sense mean on an LG dryer?
LG's airflow warnings: the display is telling you the exhaust is restricted between the dryer and the outside, by degree. Clean the duct and wall cap, straighten the hose behind the machine and re-run the installation test. The heater is not the problem. 1
