Sub-Zero Freezer Problems We Fix in Manhattan
Freezer Not Holding Temperature
A freezer that runs constantly but stays warm usually has a failed evaporator fan motor, a defrost heater or defrost thermostat fault, or a dirty condenser coil. Coil cleaning is routine maintenance and restores airflow.
Frost and Ice Build-Up
Frost on the evaporator, freezer walls or drawers means the defrost heater, thermistor or control board has stopped working. Left alone, frost blocks airflow and the freezer stops cooling.
Freezer Not Freezing at All
If the refrigerator and freezer are both warm, the compressor or sealed system, including the refrigerant charge, is the likely cause. The written estimate compares repair with replacement for built-in and panel-ready luxury condo and co-op units.
Drawer Not Closing, Torn Gasket or Water Leak
Integrated and 700 Series Sub-Zero freezer drawers wear at the slides, door seal and gasket. A drawer that will not close, a leak under the unit, an error code or a drawer ice maker that stops is repairable same day with a 90-day warranty.
