How to Replace a Freezer Door Seal

Walter H. Boelter

Freezer seals are essential to the proper operation of a freezer. Without a proper seal, a freezer is less efficient. Air leaking into the freezer carries moisture that causes rapid ice buildup, often even faster than a self-defrosting freezer can remove it. Leaky seals can also cause freezer burn or partial thawing of items in the freezer.

  1. Turn off the freezer.

  2. Remove the old seal. Most often, this will require removing the screws that hold the seal in place.

  3. Clean the seal location so the new seal has a good surface for a seal. If the old seal was held in place by adhesive, it will be necessary to scrape or wash the old adhesive off in order to get a good bond with the new adhesive. Always use a plastic scraper when a scraper is needed so you don't damage the surface you are cleaning.

  4. Install the new seal in the same way the previous seal was installed or per the instructions that came with the seal.

  5. Place the battery-powered light in the freezer.

  6. Check the new seal all the way around. Use the mirror to see some of the harder-to-reach areas.

  7. Carefully heat the seal and reshape it where there are gaps. You want to warm the seal to make it soft, not bake or burn it. Try lower heat settings first, turning on high heat only if the low setting does not soften the seal material.

  8. Remove the battery-powered light and turn the freezer back on.
