If the gasket on a refrigerator, freezer, or wine storage unit door is ripped, torn, or cracked, it should be replaced to make sure proper cooling continues and to avoid moisture issues inside the unit.

  • Gasket life can vary based on use.
  • Spills and sticky residues that are allowed to stay on the gasket will lead to premature wear.
  • 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.
