Why is my Sub-Zero freezer forming excessive frost?

Excessive frost typically results from a failing defrost timer, heater, or thermostat. It can also indicate a door gasket issue allowing warm, humid air inside.

Can you repair a Sub-Zero freezer that is not freezing at all?

Absolutely. Complete loss of cooling often points to compressor, start relay, or sealed system issues. We diagnose the exact cause and carry parts for most common repairs.

How does North Shore humidity affect my freezer?

Higher humidity near Lake Michigan means more moisture enters when the door opens. This can lead to faster frost buildup and slightly harder working conditions for the defrost system.
