Freezer and sealed system work
Sub-Zero refrigerator freezer repair for a freezer not freezing, frosting over or running constantly: defrost heater, thermistor, evaporator fan motor, compressor, start relay, overload, sealed system and refrigerant recharge, on freezer drawers, full-height freezers and the 700 series.
Frost and ice build-up
A failed Sub-Zero defrost heater or thermistor stops the defrost cycle, frost builds on the evaporator, and meltwater can leak past the drain pan. Part of our Sub-Zero refrigerator repair in NYC.
Not freezing, running constantly
A stopped evaporator fan motor leaves the freezer warm while the compressor runs, and the Sub-Zero ice maker slows with it. A Sub-Zero compressor running constantly points to the sealed system or a dirty condenser coil; the start relay and overload are tested first, and a refrigerant recharge follows only once the loss is traced. See the written estimate terms.

Where to go next
Questions we get asked on the phone
- Why is there frost on the back wall of my Sub-Zero freezer?
- The defrost cycle has stopped, usually a failed defrost heater or thermistor, so frost builds on the evaporator.
- Do you replace Sub-Zero compressors?
- Yes, with sealed system repair and a refrigerant recharge, after a written estimate you approve first.
- Why is my freezer running constantly?
- A struggling compressor, a dirty condenser coil or a sealed system fault. Coil, fans, start relay and overload are checked first.
