Thermador Refrigerator not cooling
If your Thermador refrigerator not cooling or your fridge not getting cold, start with the easy, most common fixes first. Dirty condenser coils, usually under the fridge, are the top cause; clogged coils keep the compressor from shedding heat, make the unit run harder, and can stop cooling altogether, so clean them every 6 to 12 months with a soft brush or vacuum. Next check the temperature settings and give the fridge 24 hours to stabilize after lowering temps. If those don’t help, inspect the condenser fan motor that pushes air over the coils and the evaporator fan motor that circulates cold air into the fridge—if a blade is blocked, noisy, or won’t spin, the fan motor is a likely culprit and the freezer may still be cold while the refrigerator is warm. Also check the door gasket for gaps and confirm the outlet and circuit breakers are supplying steady power.

01 - Condenser Coils are Dirty
As debris builds up on the condenser coils, usually located under the refrigerator, the appliance will become less efficient and will have to cycle on more often to maintain a cool temperature. If the condenser coils are significantly clogged with debris, the compressor may overheat and shut off prematurely, preventing the appliance from cooling at all. The condenser coils should be cleaned every 6 to 12 months by using a soft bristle brush (or a dedicated condenser coil cleaning brush) to wipe off the coils in a circular motion. A vacuum cleaner with a nozzle attachment can also be used for hard-to-reach areas.

02 - Freezer or refrigerator temperature is set too high
Verify the freezer temperature is set between 0 and 5 degrees Fahrenheit (-18 to -15 Celsius). Verify the refrigerator temperature is set between 34 and 40 degrees Fahrenheit (1 to 5 Celsius). After resetting the temperature wait 24 hours for the temperature to adjust appropriately.

03 - Thermador Refrigerator Condenser Fan Motor
The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won’t cool properly. To determine if the fan motor is defective, first check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If no obstructions are present and the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the condenser fan motor does not have continuity, replace it.

04 - Thermador Refrigerator Evaporator Fan Motor
The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, repla...

05 - Thermador Refrigerator Door Gasket
A refrigerator door gasket should form an airtight seal around the appliance's frame to keep the cold air in and the warm air out. If the door gasket is twisted or torn, gaps can form that will allow warm air in, resulting in the refrigerator not cooling properly. Inspect the door gasket for any damage and replace with a new one if necessary.
Highly Likely
06 - Incoming Power Problem
Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.
