In the realm of refrigeration, the phenomenon of evaporator coil freezing can be a persistent issue for many Thermador refrigerator owners. This occurrence not only hampers the appliance’s efficiency but also poses a risk to the longevity of its components. However, fret not, as we present to you the ultimate guide on how to prevent the Thermador refrigerator evaporator coil freezing.

Understanding Evaporator Coil Freezing

Before delving into prevention methods, it’s crucial to comprehend why evaporator coil freezing transpires. The evaporator coil is a vital component responsible for cooling the air inside the refrigerator. When this coil becomes excessively cold, moisture in the air can freeze onto its surface, forming a layer of ice. This impedes proper airflow and compromises the refrigerator’s ability to maintain optimal temperatures.

Factors Contributing to Evaporator Coil Freezing

Several factors can contribute to the freezing of evaporator coils in Thermador refrigerators. These include:

Poor Air Circulation

Insufficient airflow within the refrigerator compartment can lead to uneven cooling and subsequent coil freezing. Ensure that no obstructions are blocking the vents or interfering with the circulation of air.

Overloading the Refrigerator

Stuffing the refrigerator with an excessive amount of food items can obstruct airflow and strain the cooling system, increasing the likelihood of the evaporator coil freezing. Maintain a balanced load to prevent this issue.

Faulty Door Seals

Damaged or worn-out door seals can allow warm air from the surroundings to enter the refrigerator, causing fluctuations in temperature and promoting condensation on the evaporator coil. Regularly inspect and replace faulty seals to maintain an airtight seal.

Thermostat Issues

Inaccurate thermostat settings can cause the refrigerator to run longer than necessary, leading to excessive cooling and eventual coil freezing. Calibrate the thermostat periodically to ensure precise temperature control.

Preventive Measures

Now that we’ve identified the potential culprits behind evaporator coil freezing, let’s explore effective preventive measures to mitigate this issue:

Maintain Adequate Airflow

Arrange food items in the refrigerator in a manner that allows for proper airflow around the evaporator coil. Avoid overcrowding shelves and ensure that vents remain unobstructed.

Regular Defrosting

Periodically defrosting the refrigerator can help prevent ice buildup on the evaporator coil. Follow the manufacturer’s recommendations for defrosting frequency and procedures.

Check Door Seals

Regularly inspect the integrity of the refrigerator’s door seals and replace any damaged or worn-out seals promptly. This will help maintain a tight seal and prevent warm air infiltration.

Monitor Thermostat Settings

Ensure that the refrigerator’s thermostat is set to the recommended temperature for optimal cooling performance. Avoid setting it too low, as this can lead to excessive cooling and potential coil freezing.

Professional Maintenance

Schedule regular maintenance checks with a qualified technician to inspect the refrigerator’s components and address any issues promptly. Professional servicing can help identify potential problems before they escalate.


In conclusion, preventing evaporator coil freezing in your Thermador refrigerator is achievable through proactive maintenance and adherence to best practices. By addressing factors such as poor airflow, overloading, faulty door seals, and thermostat issues, and implementing preventive measures, you can ensure the efficient operation of your refrigerator and prolong its lifespan.
