# LG door seal replacement

### The paper test, and what it does not catch

Shut a dollar bill into the door and tug it. Anywhere it comes away with no drag at all, the seal has given up along that stretch, and it is worth trying every eight inches around all four sides of the door, because a gasket almost never fails everywhere at once. What the test misses is a seal that grips perfectly and has gone hard: those hold paper and still leak air at the corners, which is where you will find frost inside and beads of water outside. Black marks in the folds are usually mold and wash out with warm soapy water and a soft brush. A gasket still wavy an hour after the door is shut is finished.

What this involves

A paper test finds it in thirty seconds and most people never do one

It is behind a great many cooling, frost and ice complaints

Fitting evenly is the job — the part is the easy half

Test the existing seal

A strip of paper closed in the door should resist being pulled, all the way round including the bottom corners.

Check the door itself

A hinge that has dropped presents a perfect gasket to a frame it no longer matches.

Fit the new seal warm

A gasket out of a cold van will not sit. It is warmed and worked into the channel evenly.

Re-test all four sides

The paper test again, in eight places rather than one.

Recheck the cabinet a day later

Frost and temperature both take a day to settle after a seal is changed.

### My refrigerator sweats on the outside of the door. Is that the gasket?

Sometimes, and in this city often not — a cabinet in a room at eighty percent humidity condenses on its own skin whatever the seal is doing. Check inside at the same corner. If the inside is dry we would look at the room and the anti-sweat setting before selling you a gasket.

### Can a gasket be reused after the door has been off?

If it is sound, yes, and we would rather do that than sell you one. It gets checked for even seating all the way round before the job is called finished.
