Common Problems
Why a Sub-Zero Stops Cooling
Dirty condenser coil
The condenser sits at the top of built-in models, behind the grille. Dust and pet hair build up and the unit can't get rid of heat, so it runs warm and works harder. It's the most common cause we see.
Condenser fan motor
The fan pulls air across the condenser. When it stops, the compressor overheats and shuts off, and the refrigerator warms up.
Evaporator fan motor
The evaporator fan moves cold air through the compartment. A failed fan means the freezer may still be cold while the refrigerator side warms up, or the other way around.
Defrost failure
A heavy layer of frost on the back wall blocks airflow. The defrost heater, defrost thermostat or control board has usually failed.
Control board or sensors
A faulty temperature sensor or control board can stop the compressor or fans from running even though the unit has power.
Sealed system
A refrigerant leak, a restriction or a failing compressor means the unit runs but never gets cold. We diagnose and repair sealed systems in your home.

FAQ
Sub-Zero Cooling FAQ
Quick answers about Sub-Zero cooling problems, what you can check yourself, and when it's time to call for service.
How do I clean the condenser on a Sub-Zero refrigerator?
On built-in models, remove the grille at the top of the unit (it lifts or tilts out). Use a soft brush and a vacuum to clean the dust from the condenser fins, brushing in the direction of the fins so you don't bend them. Unplug the refrigerator or switch it off at the control first. Cleaning about every six months keeps it running efficiently.
Why is my Sub-Zero freezer cold but the refrigerator warm?
Most current Sub-Zero built-in models have dual refrigeration, with separate systems for the refrigerator and freezer. If only one side is warm, the problem is in that side's system: usually its evaporator fan, defrost system or sealed system.
What temperature should a Sub-Zero be set to?
Sub-Zero recommends 38°F for the refrigerator and 0°F for the freezer. These are the factory settings on most models.
What can I check before calling for service?
- Doors and gaskets: Make sure the doors close fully and the gaskets aren't torn. A door left slightly open lets in warm air and builds frost.
- Vents: Don't block the air vents inside the compartment with food containers.
- Condenser: Clean the condenser if it's dusty, then give the unit a few hours to recover.
- Power and settings: Check that the unit is on and the temperatures haven't been changed. Showroom or Sabbath mode can also change how it runs.
If it's still warm after these checks, call us. Moving food to a cooler early saves it while you wait for the technician.
