Split Ac Outdoor Unit Fan Not Working: Troubleshooting Tips to Get It Cooling Again

The outdoor unit fan of a split AC may not be working due to a potential motor or electrical problem. This malfunction can result in insufficient cooling and a decrease in energy efficiency.

Possible Causes For A Non-Functioning Split Ac Outdoor Unit Fan

Faulty Fan Motor: One possible cause for a non-functioning split AC outdoor unit fan is a faulty fan motor. The fan motor is responsible for spinning the fan blades and creating airflow. If the motor is damaged or worn out, it may fail to work properly.

Defective Capacitor: Another potential cause could be a defective capacitor. The capacitor provides the necessary electrical power to start the fan motor. If the capacitor is faulty, it may not be able to initiate the motor, resulting in a non-working fan.

Malfunctioning Fan Relay: A malfunctioning fan relay can also prevent the outdoor unit fan from working. The relay is in charge of sending the electrical signals to activate the fan motor. If the relay is not working correctly, it may fail to provide the necessary power to the motor.

Blockage in the Fan Blades: Lastly, a blockage in the fan blades can restrict its movement and prevent it from functioning. Debris or dirt accumulation can obstruct the blades and hinder their ability to rotate, leading to a non-working fan.
