How to replace the door seal on an upright freezer
A good seal will help your freezer work properly. (réfrigérateur image by dead_account from

The door seal of an upright freezer keeps warm air out and cold air in, so having a good seal helps keep energy costs down. The seal also prevents too much moisture from getting into the freezer and causing ice build-up. Door seals are soft and will wear out over time. If your freezer's door seal is cracked or rotting, you can replace it yourself. If possible, buy a seal made specifically for your freezer model from an appliance or home improvement store. However, if you can't find a seal made for your freezer, you can use a "generic" seal.

Skill level:

Things you need

  • Screwdriver
  • Rag

  1. 1

    Take all of the food out of the freezer. Unplug it and allow it to defrost.

  2. 2

    Gently pull up on the door seal until you can see the screws that attach it to the bracket inside the door. Use a screwdriver to loosen the screws until you are able to pull the seal out (you don't need to remove the screws).

  3. 3

    Lay the old seal next to its replacement, and use a razor knife to trim the new seal to the proper length. Be careful not to damage the new seal.

  4. 4

    Wet a rag and use it to clean the bracket that holds the seal in the door. Clean under and around the bracket. Dry the area with paper towels.

  5. 5

    Starting at one end, gently push the seal into place in the bracket. Tighten each screw as you come to it.

  6. 6

    Open and close the freezer door several times to test the seal. The door should close easily and seal tightly when closed.

  7. 7

    Plug in the freezer and turn it on. Wait 20 minutes to allow it to get cold, then feel carefully around the seal to check if any cold air is escaping. If you feel any cold spots, check the seal in that area to make sure the bracket is tight and there aren't any cracks in the seal.

Tips and warnings

  • Since you have already defrosted your freezer, now is a good time to wash out the inside.
  • Check the new door seal for any cracks or other flaws before you install it.
