The paper slides out with no drag, or you find a gap = the seal is leaking air and needs replacing. A bad seal can masquerade as a cooling or frost problem elsewhere in the fridge.

⚠ Unplug the fridge before opening any panel. The sealed system (compressor, refrigerant lines) is not DIY — that work needs EPA certification.
Two checks that cost nothing
- Check the water filter seat Pull the filter out and reseat it, twisting until it clicks or locks fully into place. A filter that's cross-threaded or only partway in is one of the most common reasons water shows up at the back wall of the fridge instead of flowing through where it should. Costs nothing, takes under a minute.
- Look at where the water collects Water pooling under the crisper drawers before it reaches the floor usually means the defrost drain at the back of the freezer is clogged or frozen and backing up. Water only where a supply line runs — behind the fridge, or under the dispenser — points at a fitting instead.
- Check the door seal for gaps Run your hand around the gasket, or close the door on a sheet of paper and pull. A loose or torn seal lets warm humid air in, which can show up as extra condensation and dripping around the door rather than a true water leak.
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.

How to check. Close the door on a sheet of paper and pull, or run your hand around the whole gasket feeling for a stiff, torn, or misshapen section.

water filter#4 most-watched · 0.8% of repair videosFree to check $39.99
How to check. Check the date on the filter housing against its recommended replacement interval, and look for a printed install or expiration date.
Overdue = the filter is very likely restricting flow, which shows up as slow filling, weak ice production, or an indicator light — not as a broken part elsewhere.

ice maker#3 most-watched · 2.3% of repair videos $218.81
How to check. Check the fill tube for an ice plug and the arm/switch position first.
A whole assembly is rarely needed — check the inlet valve and fill tube first.
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.

water inlet valve#5 most-watched · 0.8% of repair videos $105.00
How to check. Test continuity across the valve's coil terminals, and check the screen inside the inlet for mineral buildup blocking flow.
No continuity, or a fully blocked screen = the valve isn't opening — or isn't opening enough — to fill the line, tray, or dispenser.

defrost heater#2 most-watched · 33.5% of repair videos —
How to check. Test continuity across the heater element under the evaporator.
No continuity = the defrost cycle runs but nothing melts.
No confirmed LG part for this yet. The diagnosis and the walkthrough still apply — but we would rather show you nothing than a part from a different manufacturer. Check your model's parts list before ordering anything for this cause.
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 268 LG refrigerator 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 633 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 refrigerators have a fully verified repair page — every failure sourced, every part confirmed on that exact machine, rather than matched at family level as above.
