Troubleshooting:

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. 

Gasket Maintenance

Gasket life can vary based on use. Heavy use causes the gasket to last for a shorter amount of time.

Sticky residue and spills that stay on the gasket will lead to premature wear or cracking.

• Keep door gaskets clean to prolong life.
