Repair A Freezer Door Seal

A freezer door has a door seal placed around the inside edge. The purpose of this seal is to ensure that the freezer has an early air-tight seal at the door, which helps to keep the cool air in and prevent warmer air from entering the freezer. It also helps to limit the amount of moisture which is able to get into the freezer, controlling ice buildup. Periodically, this seal will begin to wear out. If you notice signs of cracking or rotting in the seal, your freezer door seal is probably wearing out. Replacing a worn seal will protect your food while conserving energy.

Step 1: Buy the Seal

If possible try to find a door seal which is designed for your freezer. If this cannot be done, you will be able to find generic door seals at most hardware stores. You will need to cut the seal to the correct sizes for proper operation. Before beginning inspect the seal carefully. Look for cracks, tears or weak looking spots which may cause problems.

Step 2: Defrost Freezer

Before you begin you will need the freezer to be defrosted. This is to make sure there is no ice buildup behind the existing door seal and to allow you to clean it more easily before installing the new seal. Remove all of the food in your freezer and disconnect the freezer. Leave the door open until it has fully defrosted.

Step 3: Remove the Door Seal

There is a brace on the underside of the door which holds the seal in place. You will need to loosen the brace. If you lift the seal up gently, you will expose the screws holding the brace in place. Loosen these until you are able to pull the seal out. It is not necessary to remove the screws completely.

Step 5: Clean the Bracket

Use a rag to clean under and around the bracket that holds the seal in place. This would also be a good time to clean the inside of the freezer thoroughly while all the food is out and it is defrosted.

Step 6: Install the New Seal

Gently push the new seal in underneath the bracket. As you move along tighten each one of the screws down until it is firmly in place.

Step 7: Test the New Seal

Open and close the door several times. If the seal is functioning properly, the door should close tightly. Turn the freezer back on and allow it 15 to 20 minutes to get cold. Run your fingers along the edges to determine if you feel any sections where cold air appears to be coming out. If you feel any cool areas, open the freezer and check the seal in those locations for cracks and to ensure that the bracket is tight.
