Steps to Verify Issue:

The gasket is the rubber seal that goes around the edge of the inner door. This helps to make sure proper cooling continues and to avoid moisture issues inside the unit. If the gasket on a refrigerator, freezer, or Wine Storage door is ripped, torn, or cracked, it should be replaced.

Gasket Tips

  • Gasket life can vary based on use.
  • Sticky residue and spills that stay on the gasket will lead to premature wear or cracking.
  • Heavy use causes the gasket to last for a shorter amount of time.
  • Keep door gaskets clean to prolong life.
  • Some door gaskets have stronger pull than others, refer to Sub-Zero Door Easy to Open for more information.
