Why does this happen, and is there anything that can be done to fix it?

Why is My Outdoor AC Fan Not Spinning?

If your AC fan is not working properly, it may be indicated by one or more of the following signs:

  • The AC fan blades are moving slowly

  • After turning off the AC, the fan won’t stop spinning
  • When the fan rotates, there are strange noises coming from the condenser unit

8 Reasons Why Your AC Fan Isn’t Spinning and How to Troubleshoot or Fix

If after checking your AC unit you find out your AC fan isn’t spinning, here are some of the reasons this might be happening and what you can do to fix the problem:

1. Tripped Breaker

Occasionally, parts of your AC might get overheated and cause your circuit breaker to trip. When this happens, switch it back to the middle setting prior to switching it on. If this is a recurring issue, it could be a sign of a more serious issue that needs to be investigated by a professional HVAC technician.

2. AC Fan Motor is Not Working

If your AC fan is not spinning, it could simply be that the motor has died. A dead fan motor is one of the most common causes for this problem, and it usually occurs in AC systems that have not been regularly maintained . The easiest way to resolve it is to replace the fan motor and schedule regular AC maintenance.

3. Burnt Out Motor

Over time, fan motors go through a lot of wear and tear and can eventually burn out, especially if not properly maintained. This usually requires a technician to fix and the system might need to be completely replaced.

4. Broken AC Compressor

The compressor works by circulating and applying energy to the refrigerant in your HVAC system. When it breaks, you’ll notice a lot of undesirable signs with your AC, including a fan motor that’s stopped spinning. Fixing or replacing a compressor requires professional HVAC service. If you suspect your AC compressor may be broken, call us to schedule your service appointment today.

5. Failing AC Contactor

A contactor is an electrical switch that controls the flow of electricity to components in the AC unit, like the fan motor. It’s common that the contactor can go bad over time due to stress and overuse on the unit. Over time, normal wear and tear can cause the contactor to overheat and fail.

6. Bad Capacitor

The capacitor sends power to the motor that provides your AC the energy it needs to turn on and run continuously. A bad capacitor can cause your AC fan to not spin, as well as affect various other components of your system. If you have a bad capacitor, the good news is capacitors are readily available and not nearly as costly as other AC parts. Therefore, your HVAC technician will be able to quickly replace the capacitor and restore your home’s comfort before you know it.

7. Check the Float Switch

The float switch is located inside your unit and is meant to shut it down if water begins to accumulate in the drain line. Depending on how your system is designed, it may turn off the whole system or just the condensing unit.

8. Condenser Fan Motor Failure

If the condenser experiences electrical failures, the motors inside the condenser that operate the fan and the motor may stop working. If the condenser continues to malfunction, it could severely damage or even stop the AC unit from cooling your home.
