Sub Zero Refrigerator Fan Not Running

A refrigerator fan not running is a common issue that can occur in various models and brands of refrigerators. Here are some steps you can follow to troubleshoot the problem:

1. Check the power source: Make sure that the refrigerator is plugged into a working electrical outlet and that the circuit breaker has not tripped.

2. Check the fan motor: The fan motor may be defective if the fan is not running. To check the fan motor, unplug the refrigerator and use a multimeter to test it for continuity. If the motor does not have continuity, it needs to be replaced.

3. Check the fan blades: If the fan blades are dirty or obstructed, they may not spin properly. Clean the fan blades and remove any obstructions, such as food or debris.

4. Check the condenser coils: The condenser coils in the refrigerator may be dirty if the fan is not running. Clean the condenser coils with a coil brush and vacuum.

5. Check the evaporator coils: The evaporator coils in the refrigerator may be iced over if the fan is not running. Defrost the evaporator coils by unplugging the refrigerator and allowing it to thaw for a few hours.

6. Check the fan switch: The fan switch may be defective if the fan is not running. To check the fan switch, unplug the refrigerator and use a multimeter to test it for continuity. If the switch does not have continuity, it needs to be replaced.

7. Check the fan relay: The fan relay may be defective if the fan is not running. To check the fan relay, unplug the refrigerator and use a multimeter to test it for continuity. If the relay does not have continuity, it needs to be replaced.

If none of these steps solve the problem, you may need to contact a professional appliance repair technician to diagnose and repair the issue.

What Are The Possible Causes Of A Sub Zero Refrigerator Fan Not Running?

• 1. Defective fan motor: The fan motor may be damaged due to overuse, overheating, or a power surge. This can cause the fan to stop working, resulting in a lack of air flow inside the refrigerator.
• 2. Clogged condenser coils: Condenser coils are responsible for dissipating heat from the refrigerant. If they become clogged with dust, dirt, or debris, they may not be able to effectively cool the refrigerant, causing the fan to work harder and eventually stop running.
• 3. Defective thermostat: The thermostat is responsible for regulating the temperature inside the refrigerator. If it becomes defective, it may not send the proper signals to the fan, causing it to stop running.
• 4. Loose electrical connections: The fan motor and thermostat are connected to the circuit board inside the refrigerator. If any of these connections become loose, the fan may not receive the proper voltage, causing it to stop running.
• 5. Ice buildup: Ice buildup on the fan blades can cause the fan to stop working. This can occur if the refrigerator is not defrosted regularly or if the door is opened frequently, allowing warm air to enter the refrigerator and cause condensation.
