Thermador Evaporator Fan Not Circulating Air

Freezer cold but refrigerator warm; ice buildup on back wall of freezer.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed evaporator fan motor, Ice blocking fan, Broken fan blade, Faulty door switch preventing fan operation

Safety first: Unplug the refrigerator before accessing the fan.

Steps to check:

Inspect for frost: Remove the freezer rear panel. If the fan is encased in ice, defrost the area carefully.
Check fan operation: After defrosting, restore power and close the door switch manually. The fan should run when the compressor is on.
Replace fan: If the fan does not run and has proper voltage, replace the evaporator fan motor with a Thermador-compatible unit.
Verify door switch: Test the door switch for continuity; replace if it fails.
