- Plug in the refrigerator and turn the thermostat to the lowest setting. Wait for about 10 to 15 minutes. If the refrigerator stops working while still not cold enough, the thermostat relay may be faulty.
- You can test the relay using a multimeter (VOM) to measure at normal temperature. Both electrical terminals should be conducting. Alternatively, visually inspect for any broken or missing sensor heads, indicating a likely faulty relay.
If the refrigerator thermostat relay is faulty, avoid DIY repairs at home. Contact a reputable refrigeration repair center to avoid damaging other components and to receive proper troubleshooting and assistance.

How to Check Refrigerator Thermostat Relay
Below are some signs indicating a faulty refrigerator thermostat relay:
- The refrigerator operates continuously without any interruption. In this case, the thermostat relay of the refrigerator is experiencing issues, preventing the refrigerator from shutting off even when the temperature is reached.
- The temperature drops excessively, causing cold air to escape. This indicates that the refrigerator thermostat relay is stuck, unable to turn off, so the refrigerator continues to cool, resulting in lower-than-normal temperatures.
- Frost and ice build-up in the freezer compartment occur because the thermostat relay fails to automatically shut off, causing cold air to blow continuously inside.
- The refrigerator does not cool or cools very weakly.
- The refrigerator cycles on and off continuously for many hours, yet it still operates normally.
Note: It is not advisable to dismantle refrigerator components on your own as it can easily affect other parts. Please contact a repair and warranty center to receive guidance from experts on how to properly address issues with the refrigerator thermostat relay.
