Freezers rely on a flexible plastic or rubber gasket to maintain a seal on the door to keep the cold air in and the warm air out. If the gasket isn’t sealing properly, your freezer must work harder to maintain the interior temperature. This raises your electric bill and can lead to food spoilage from not being kept cold enough. Test your freezer gasket every three months to make sure the gasket is doing its job. A gasket that is not sealing must be replaced. You can buy a freezer gasket replacement kit for your make and model and do the job yourself, or you can have the job done by a service technician.
With a flashlight, inspect the freezer gasket for tears, holes and other visible damage. Check the insides and outsides of the gasket around the entire door. Pull gently on the gasket to check for suppleness and to check the folds for hidden damage.
Close the freezer door on a crisp dollar bill. The bill’s paper is the perfect thickness for checking gasket seals. Pull out the bill. You should feel resistance. If the bill slips out easily, your gasket isn’t sealing and should be replaced. Test along the length of the sides, top and bottom. Test each corner.
Clean the gasket with a solution of 1 tsp. of mild dish detergent in ½ gallon of water to help prevent future problems. Dip an old toothbrush in the detergent solution and gently scrub the gasket to clean out dirt and grime. Wipe dry with a clean, soft cloth.
Clean the surface where the door gasket makes contact.
