Most Common Causes and Quick Fixes

1. Dirty Condenser Coils

Dust and pet hair can cover the condenser coils. These coils are usually located at the back or underneath the refrigerator. As a result, heat cannot escape properly. The refrigerator may then struggle to stay cool. Therefore, clean the coils with a soft brush or vacuum attachment.

2. Blocked Air Vents

Overpacking the refrigerator can block the air vents. Large food containers can also restrict airflow. As a result, cold air cannot circulate properly from the freezer to the refrigerator compartment. Therefore, keep the vents clear and avoid overloading the shelves.

3. Faulty Door Gaskets

Damaged or dirty door gaskets can let warm air enter the refrigerator. Consequently, the refrigerator may run continuously to maintain the correct temperature. Frost can also build up inside the unit. Therefore, clean the gasket and check it for cracks or damage.

4. Frosting Evaporator Coils

Ice can build up on the evaporator coils when the defrost system fails. A faulty defrost heater or timer can cause this problem. As a result, cold air becomes trapped behind the freezer wall. Therefore, the refrigerator may not cool the main compartment properly.

5. Failed Evaporator or Condenser Fan

The fans help move air through the refrigerator. However, a faulty fan motor can stop proper airflow. If the evaporator fan in the freezer stops, cold air may not reach the refrigerator compartment. Therefore, unusual fan noises should be checked by a technician.

6. Failing Compressor or Start Relay

A failing compressor can cause serious cooling problems. For example, you may hear a faint clicking sound every few minutes. In some cases, the refrigerator stays silent even though the interior light works. As a result, the compressor may not be starting correctly. A technician should inspect the compressor and start relay.
