Thermador Refrigerator: not cooling
What is this symptom?
Is your Thermador refrigerator not cooling properly? You may notice that food in both the fridge and freezer compartments is not reaching the desired temperatures. Although the unit powers on and internal lights function, inadequate cooling can lead to spoilage. Explore common causes and solutions to restore optimal performance.
Important Tips for Thermador Models
- Official Thermador support provides general troubleshooting but often advises contacting customer support for cooling issues not resolved by basic steps.
Possible Causes
Condenser fan motor failure
How to Identify: No airflow over condenser coils; fan doesn’t spin even with power on; elevated compressor temperature.
Part: Condenser fan motor
Dirty or obstructed condenser coils
How to Identify: Visible dust/debris on condenser coils at back/bottom; fridge runs longer and gets warm inside.
Part: Condenser coils
Incorrect temperature settings or internal air circulation block
How to Identify: Temperature set too warm; shelves/food blocking air vents; uneven temperature distribution.
Part: Temperature control / internal vents
Door gasket seal failure
How to Identify: Warm air infiltration; visible gap or worn gasket; watery condensation near door edges.
Part: Door gasket
Thermostat or temperature control module fault
How to Identify: Refrigerator doesn’t trigger cooling cycles despite correct settings; erratic temperature behavior.
Part: Thermostat / control board
Compressor or sealed system failure
How to Identify: No cooling at all; loud unusual noises from compressor; overheats; fridge runs continuously without cooling.
Part: Compressor / sealed refrigerant system
DIY Solutions
Clean condenser coils
- Unplug the refrigerator.
- Locate condenser coils (back or bottom panel).
- Use a brush and vacuum to remove dust/debris from coils.
- Reassemble and plug in refrigerator.
Check and adjust temperature settings and clear internal vents
- Verify temperature settings are set to recommended cold levels.
- Rearrange contents so vents are not blocked.
- Allow several hours to see if temperature normalizes.
Inspect and clean door gaskets
- Wipe gaskets clean to remove debris.
- Check for damage or gaps.
- Replace gasket if visibly worn.
Next step
Choose the next step for not cooling
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Condenser Fan Motor
Moves air across the condenser and compressor compartment to remove heat.
- Typical part-only price
- $35 - $100
- DIY difficulty
- Medium
- Estimated time
- 30-60 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Condenser Coil Assembly
Releases heat from the refrigerant circuit and must match the appliance's sealed-system design.
Door Gasket
Creates a watertight seal around the door to prevent leaks during operation.
Thermostat
Regulates temperature by turning the heating or cooling system on or off.
Model-compatible Refrigerator parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.

Optional routine care
Maintenance supplies
These products support cleaning or routine upkeep. They are separate from the possible repair components above and are not claimed to fix this error code or symptom.
Refrigerator Condenser Coil Brush
For routine cleaning of accessible condenser areas where the manufacturer permits it. It does not repair a sealed-system or compressor fault.
Model-Compatible Refrigerator Water Filter
A routine replacement item on models with a water filter. Match the complete appliance model and existing filter number before ordering.
Compatibility check required: use the complete appliance model and compare the existing filter, bag, or specification before ordering.
