Why did my air conditioner’s fan stop working?

It’s best for your HVAC company to diagnose any issues with your air conditioner if it is running but the fan isn’t spinning and there isn’t cool air. The following are possible causes of your air conditioner’s fan not working:

Problems with the capacitor

A dead capacitor is one of the main reasons fans stop spinning. The capacitors in an AC are tiny, cylindrical components that transmit energy signals to the fan motor and other parts of the AC unit. There are several capacitors in an air conditioner system. The start capacitor sends signals to motor and the run capacitor keeps motor running. Over time, capacitors can become damaged and should be replaced.

Power issues

Sometimes it is as simple as a power problem. Overheating can cause the AC to stop working if the circuit breaker trips. You can fix this by flipping the circuit breaker switch.

Motor is ruined

A burned out fan motor is another reason why fans quit working. Fan motors can become corroded and fail if they are subject to excessive wear. The replacement of AC fan motors can be costly and could lead to system replacement.

Air filter that is blocked

Blocked air filters can block air flow and cause ice buildup. This can put more strain on the fan, which can cause it shut down. To ensure proper airflow, make sure to change your HVAC filters often.

Faulty belt

An older AC condenser uses a belt. Belts can wear down or become damaged over time. An HVAC technician can fix this problem, but it might be time for a system replacement.

Problems with the contactor

Your AC’s contactor switch is located within your compressor unit. It sends voltage to the fan and condenser units so that they can run. The contactor switches can become faulty over time and cause your fan to stop functioning properly. An HVAC contractor should replace the contactors.
