When the door is shut, the gasket on the fridge or freezer door prevents air from entering or escaping the cabinet. When the door is closed, a damaged gasket lets warm, moist air into the fridge. The door seal should be replaced if it's damaged.
Follow these steps to fix your issue:
Remove creases in the new door gasket
If you want to smooth out the folds in the door gasket, soak it in warm water and dry it with a towel. Carefully warm it with a hair dryer or heat gun. It's important to not melt the gasket. The door gasket expands when heating it. If the gasket seems too big for the door after heating, it's a good idea to cool it.
Remove the refrigerator door gasket
Shut off the circuit breaker for the fridge or turn it off. The gasket needs to be pulled out of the track. It's easiest to start at one of the corners. To start the removal process, you need to tug the gasket firmly. Pull the gasket out from the side of the door if you have a hard time starting at a corner. You should be able to pull the gasket out easily once the removal process starts.
Clean the track in the refrigerator door
If there are spills around the track, wipe them off with a wet cloth. The track needs to be cleaned to make sure the gasket fits in the track and seals the door correctly.
Install the new gasket
Start at the top of the door and work the gasket into the track. You can go down both sides of the door. Check for loose spots and adjust the gasket for a proper fit. To help the new gasket seal properly, spread a thin coat of petroleum jelly along the seal surface of the door gasket. If you want to check the fit, close the door. There should be no gaps between the cabinet and door. It's a good idea to smooth out any gaps. The door gasket should be pushed further into the track to eliminate gaps.
You would need the following tools:
hair dryer or heat gun, petroleum jelly.
