How to replace a door gasket in a French-door refrigerator

To smooth creases and folds in the door gasket, soak it in warm water and dry with a towel. Or carefully warm it with a hair dryer or heat gun on a low setting.

Be careful not to melt the gasket.

First, unplug the refrigerator or shut off the circuit breaker for the refrigerator.

Pull the gasket out of the track. Starting at one of the corners is usually easiest. You may need to tug the gasket firmly to get the removal process started. If you have a difficult time starting at a corner, pull the gasket out starting in a spot halfway down the side of the door.

Once you get the removal process started, you should be able to pull the gasket out fairly easily.

If you're replacing the gasket on the door with the flipper mullion and the mullion blocks door gasket removal, remove the flipper mullion.

Remove the mounting screws from the center mullion bracket.

Lift the mullion up slightly and release it from its top and bottom mounting brackets.

Pull the mullion out slightly and disconnect its wire harness.

Set the flipper mullion aside while you replace the door gasket.

Using a wet cloth, wipe any spills from inside and around the track.

Cleaning the track will ensure that the new gasket fits easily in the track and seals the door properly.

Starting at the top of the door, work the new door gasket into the track. Work your way down both sides of the door and across the bottom.

Check for loose spots and adjust the gasket as needed for a proper fit.

Spread a thin coat of petroleum jelly along the sealing surface of the door gasket to help the new gasket seal properly.

Reinstall the flipper mullion if you pulled it off to remove the gasket.

Close the door and check the fit. The door gasket should fit tightly against the cabinet and door with no gaps showing. Smooth out any creases that cause gaps. Push the door gasket further into the track to eliminate gaps.

Restore power to the refrigerator.

Use the same procedure to replace the freezer door gasket.
