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

Why is My Outdoor AC Unit's Fan Not Spinning?

There is nothing more frustrating than when your air conditioner has stopped blowing cool air during the middle of the summer. Now what? After performing a surface inspection of the AC unit to discover the source of the problem you notice that the fan is not spinning. If this is the case, it's important to determine the cause right away.

Common Reasons Your AC Fan Is Not Turning

Whether the fan will not start at all or only runs sporadically, there may be a variety of reasons behind the problem.

Start Capacitor Breakdown

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

If the unit has trouble starting, the fan motor will not start either. As a result, your AC’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

Faulty installation may affect the power that runs through the electrical wiring 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.
