How to replace a door gasket in a top-freezer 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, turn off or 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.

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

Cleaning the track ensures 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.

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.

Turn the refrigerator back on or restore power to the refrigerator.

Use the same procedure to replace the freezer door gasket.
