Sub-Zero gaskets are magnetic seals around each door and drawer. A torn, flattened or shrunken gasket lets warm air in, causing frost, condensation, long run times and door ajar alarms. Replacement requires the correct gasket and careful door alignment.
What It Does
The gasket seals the cabinet and helps keep the door closed with magnetic strips. Sub-Zero doors rely on both the gasket and the hinge closer to seal.
Symptoms of Failure
- Visible tears or flat spots
- Frost near the door
- Condensation on the cabinet
- Door ajar alarm
- Dollar bill slides out easily
Why It Fails
- Age and wear
- Cleaning chemicals
- Door misalignment pinching the gasket
