⚠ Unplug the machine before opening it. On a 240V dryer that means pulling the cord, not just switching it off at the panel.
Two checks that cost nothing
- Write down the exact code Note every character and any blink pattern exactly — a single letter or digit changes the meaning. If the code cycles through a light sequence rather than a screen, count the blinks and the pause between them. This takes ten seconds and it's the one thing you need before doing anything else.
- Look it up in the machine's own manual Search the model number plus the exact code, or check the paper manual if you kept it. Error codes are brand-specific and even change between model years on the same brand — a description you find online for a different make isn't reliable information for this machine.
- Try a power reset Unplug the dryer for a minute, or trip the breaker, then restart it. This clears a false reading in a real share of cases without pointing at a failed part at all — worth doing once you've noted the code.
Check each cause, easiest first
Ordered by how hard each is to check, not by how likely it is — so the cheap answers get ruled out before you open anything. The badge on each row shows where the smart money is. Percentages are share of repair-video attention, not a measured failure rate.
blower wheel#5 most-watched · 6.9% of repair videos $63.65
How to check. With the machine unplugged, reach in and spin the blower wheel by hand. Listen for scraping and feel for wobble or looseness where it mounts to the motor shaft, and check for lint packed around it.
⚡ This one check needs the appliance plugged IN and running — the rest do not. Keep hands clear of the panel, touch nothing inside while it is live, and unplug again before replacing anything.
A cracked hub or debris caught in the fins is a common source of a rattling or grinding noise, and a wheel that's loose on the shaft gets worse over time, not better. A packed wheel also restricts airflow, which can affect heat as well as noise.

door switch#6 most-watched · 6.7% of repair videos $31.95
How to check. With the machine unplugged, press the switch by hand — most give a distinct click. Test continuity across its terminals with the switch held in the closed position.
No click, or no continuity when closed, means the control never gets the 'door closed' signal, so the cycle won't start even though the door looks shut.

thermistor#1 most-watched · 32.8% of repair videos $12.44
How to check. Test resistance and compare against the value in the machine's tech sheet.
Out of range = the control is being told the wrong temperature.

thermal fuse#2 most-watched · 24.9% of repair videos $9.37
How to check. Test continuity across the fuse near the blower or exhaust duct.
No continuity = blown. This is a one-shot safety device — it blew for a reason, and that reason is nearly always a blocked vent.

heating element#4 most-watched · 7.0% of repair videos $226.11
How to check. Look at the coil through the housing — a visible break or a burnt spot is a definite fail. Otherwise test continuity across its terminals.
No continuity = the element is open — you've found your problem.

control board#3 most-watched · 21.7% of repair videosPro job $76.97
How to check. Last resort. Only after the element, thermostat and fuse all test good.
Boards are the most expensive part here and the least likely cause — do not start with this one.
Our own diagnosis above says to check the cheaper parts first. Only buy this once those have tested good — it is one of the more expensive parts here.

Can the manufacturer refuse to sell you this part? It depends on your state.
If a control board turns out to be your fault, you may need an official part. Whether a manufacturer has to sell you one is state law, not company policy — and it is not uniform.
| California | covered | SB-244 names major appliances explicitly. Parts, tools and documentation must be offered on fair terms — 7 years for parts wholesaling at $100+. |
|---|---|---|
| Colorado | covered | HB24-1121's 14-item exclusion list omits appliances, so they are covered. Includes a parts-pairing ban. |
| Oregon | covered | Appliances are not excluded from Oregon's right-to-repair statute. |
| Minnesota | likely covered | Appliances are not named as excluded and the definition is broad, but the statute does not name them either — read as covered, not confirmed. |
| New York | excluded | Home appliances are carved out BY NAME from the Digital Fair Repair Act. A manufacturer is not required to sell you this part. |
| Texas | excluded | Appliances are explicitly excluded from the state's repair statute. |
Enforcement is by the state Attorney General in every state confirmed — none of these laws gives you a personal right to sue. Sourced from primary statute text; see our right-to-repair notes for citations.
Is it worth fixing at all?
Most pages answer this with the “50% rule” — spend no more than half a replacement's price. We went looking for the origin of that number and could not find one: it is widely credited to ENERGY STAR, whose actual published guidance is an age-and-condition checklist with no percentage in it. We use your machine's own measured running cost instead. We hold it for 217 LG dryer models.

When to stop and call someone
Leave the appliance alone, ventilate, and call the gas utility. Nothing on this page is worth doing around a suspected leak.
Compressor and refrigerant repairs need EPA certification — that is a legal requirement, not a difficulty rating. A service call runs roughly $75–$150 before parts, so read the repair-or-replace maths above before booking.
Common questions
Share of repair-video views for this symptom across 363 videos. The walkthroughs shown on this page come from AppliancePartsPros and RepairClinic.com. It measures what people watch. That correlates with what fails, but video age, channel size and search visibility all influence it, so we publish it as attention and never as a failure rate. Each cause shows the video count and total views behind its percentage.
We only show a part when it comes from a repair on a machine in the same LG family. Where we have no family-matched part we say so rather than substitute another brand's. For parts confirmed on one exact machine, use the model page above.
Usually yes for simple mechanical parts like belts, fuses and thermostats; less reliably for control boards and sensors, where tolerances and firmware matter. Every listing is labelled.
Know your model number?
These LG dryers have a fully verified repair page — every failure sourced, every part confirmed on that exact machine, rather than matched at family level as above.
