Sub-Zero Refrigerator Freezer Not Freezing: Manhattan Repair

Sub-Zero refrigerator repair for a freezer not freezing in Manhattan begins with a diagnosis of frost, the defrost heater, thermistor, evaporator fan motor, compressor and sealed system.

Sub-Zero freezer frost, ice build-up and temperature

The defrost cycle has stopped: a failed defrost heater, thermistor or control leaves frost on the evaporator and the temperature climbs. Warm food, soft ice cream and a freezer door not sealing are the first signs.

Sub-Zero freezer not freezing

• Evaporator fan and fan motor stopped or iced over
• Condenser coil blocked, so the compressor runs hot
• Door gasket or seal torn, drawers not closing
• Control board or error code on the display

Sub-Zero compressor running constantly, noise and leaks

A struggling compressor, a sealed system fault or a low refrigerant charge keeps the unit running, with noise and a leak from the defrost drain. We repair it in your kitchen with genuine OEM parts and a parts and labor warranty.
