Answer: A fan could be running slow due to low voltage. This could be also due to circuit failure in the condenser unit. Also check for power to the fan. It could be just running out of the breeze. Inspect the state of the motor shaft and the fan belt. If they are worn they should be replaced. A slow condenser fan can be the result of a non-working capacitor and a burned-out compressor motor. It can be caused due to tripped breaker or a blown fuse in the condenser unit. Overcurrent in the compressor can also cause the fan to run slow.
