Why Is My Outdoor A/C Unit's Fan Not Spinning?

It is really frustrating to know that your air conditioner has stopped blowing in the cool air. Now what? Of course, you will check the unit to see the source of the problem. Doing a surface unit inspection includes checking your condenser’s fan. When you notice that the fan is not spinning, you need to get into the issue right away.

Whether the fan will not start or runs sporadically, you need to know the reasons behind the problem. If your outdoor unit’s fan is not turning, here are the possible reasons.

Common Reasons Your AC's Fan Isn't Working

  • Start Capacitor Breakdown

Capacitors are composed of electric devices used to run the electric motor in the condenser unit. As long as the capacitor is running, the motor also runs. But when it fails, the fan motor will spin slowly until it stops working. Similar to batteries, capacitors may also shut down because of high voltage or high temperature. With extreme outdoor temperature, the capacitor will stop doing its job. Try turning your condenser on and off to see if the fan works. If it stays at rest, then bring in professionals for expert help.

  • Defective Condenser Unit

Sometimes, the problem lies in the condenser unit itself. A faulty outdoor unit may cause the fan not to spin no matter how hard it tries. If the unit has trouble starting, the fan motor will not start either. As a result, your A/C’s outdoor fan will no longer spin which restricts the air from circulating properly in the entire house. If you experience a problem such as this, do not hesitate to call A-TEMP for inspection and repair services.

  • Faulty Condenser Installation

There are cases that the fan motor does not spin because the outdoor unit is incorrectly installed. Faulty installation may affect the power that runs through the electrical wirings connecting every component of the condenser. When the unit is positioned at the wrong angle, the compressor will not do its job in delivering the right amount of power into the fan motor. In this situation, checking the circuit breaker will help you come up with the right and effective solution.
