Steps to Verify Issue:

The gasket is the rubber seal that goes around the edge of the inner door.

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

Sub-Zero recommends that a service technician completes any door or drawer gasket replacement. Contact Factory Certified Service to schedule an appointment for repair.

  • Gasket life can vary based on use.
  • Sticky residue and spills 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.
