How to replace a refrigerator door gasket: is the gasket really the problem?

Close the door on a strip of paper or a banknote at several points around the door. If the paper slides out easily, the seal is weak there. Look for tears, cracks, mildew, stiff or flattened sections, and gaps. If the door also hangs crooked or sags, check the hinges and level before blaming the gasket.

Quick facts: how to replace a refrigerator door gasket
Time needed	30 to 60 minutes
Tools	Hair dryer, screwdriver or nut driver, putty knife, warm water, cloth
Difficulty	Easy to moderate
Parts	The exact gasket for your model number

Before you start

1. Find the model number on the label inside the fridge, and order the exact gasket. Colour and profile matter.
2. Soften the new gasket. Soak it in warm (not boiling) water for several minutes, or use a hair dryer, so it relaxes and unrolls without wrinkles.
3. Empty the door shelves if they are in the way, and unplug the fridge if you will be working near wiring.

Steps

1. Loosen the old gasket. Most are held by a retainer strip, screws, or push-in barbs. Pull back the lip and loosen screws a few turns, or ease the barbs out of the channel.
2. Remove the old gasket, and clean the channel with warm soapy water and a cloth. Remove any old adhesive.
3. Align the new gasket at the top corners and tuck the barbed or flanged edge into the channel.
4. Work around the door, pressing the gasket into place bit by bit, and tighten any retainer screws gently as you go.
5. Use a hair dryer to warm any stiff sections, and smooth wrinkles with your fingers.
6. Close the door and check that it seals all round. Adjust it if it does not.
7. Let the gasket settle overnight with the door closed.
8. Re-test with the paper to confirm a tight seal.

Common gasket types

Type	How it attaches
Push-in (barbed)	Tucks into a channel in the door
Screw-in with a retainer	Held under a metal strip fixed with screws
Magnetic strip	Gasket with a magnet in the seal; handle gently
Adhesive	Rare, glued to the door

Fixing small problems without replacing

A gasket that is slightly out of shape can sometimes be revived. Warm it with a hair dryer and press it flat, or clean mildew with warm soapy water and a soft brush. A thin smear of petroleum jelly on a dry or sticky gasket can help it slide and seal. If the gasket is torn, cracked or hard, replacement is the right call.

Signs a good gasket is not enough

If the door still does not seal after fitting, the door may be misaligned or the fridge not level. Adjust the front feet so that the cabinet tilts slightly back, and check the hinge screws. A persistent gap may need a technician.

When to call a professional

Call if the door is warped or damaged, if you cannot find the gasket part number, or if the fridge still runs constantly after a new gasket.

After the job

Wipe the gasket every few months, keep the door shelves from overloading, and re-test the seal each season. If you are unsure how to replace a refrigerator door gasket on a built-in or sealed-door model, ask the manufacturer for the instructions for that model.
