About the Door Gasket

The door gasket prevents air from leaking into or out of the freezer. If the door gasket is torn or not creating a reliable seal, or if the freezer is not shut tightly, humid air can leak into the freezer. When this humid air passes over the cold evaporator coils, it condenses and freezes on the coils. If humid air is continually leaking into the freezer, the evaporator coils ice over too quickly, and the defrost cycle isn’t able to keep up which can prevent the freezer from freezing properly. To determine if the gasket is creating a reliable seal, close the freezer door on a dollar bill and try to pull the dollar bill out of the freezer door. If the dollar bill sticks in place, the gasket is creating a good seal. If the dollar bill slides out or falls out, the gasket has a leak. Repeat this procedure all the way around the refrigerator door. If, at any point, the dollar bill does not stick, the gasket is defective. If the door gasket is defective, replace it.
