Air Conditioner Fan Not Working?

How to Repair an HVAC Fan

As a heating and cooling service company, the most common issue that we find is an air conditioner fan isn't working. In most cases the HVAC fan isn't rotating, however, the rest of the system is still running. There are a few possible reasons for this issue, but the most common cause is a damaged capacitor. The capacitor is what provides the air conditioning follower its energy to launch. If the capacitor isn't functioning properly, the HVAC fan won't either.

Is Your Air Conditioning Follower AND Compressor Not Running?

It's important to distinguish between an HVAC fan that isn't working, an air conditioner fan, and also a compressor that isn't functioning. If you don't hear your outside HVAC system at all, then it's likely a power issue. To troubleshoot this issue follow the steps below.

• Switch off your air conditioner unit if you haven't already. This can be done on the thermostat.
• Examine your circuit breaker panel and see if the circuit breaker tripped somehow. Be on the lookout for "COOLING AND HEATING", "Air Conditioner" or words similar to those. If the breaker did trip, simply reset it. If the circuit breaker didn't trip, you can switch it off for a short while and then turn it back on.
• Switch the power back on to your air conditioning unit and see if the outside unit works properly.

If this doesn't fix your problem, please call your local HVAC repair business. The problem with your external HVAC machine needs to be repaired by a trained specialist.

If your compressor is running as it should, you should hear it humming. If your compressor is running but your air conditioning follower is not functioning, read below.

Why Your HVAC Fan is Not Working

As we specified previously, one of the most typical reasons for an air conditioning fan not working is a defective capacitor. While this is one of the most common causes, there are a few other things to consider.

• A power supply issue
• An icy HVAC system
• A damaged HVAC fan motor
• A poor contactor
• Belt slippage with older systems

We hope this has given you some understanding regarding why your air conditioner fan isn't functioning effectively. For the most part, the trouble is a power supply issue, a bad capacitor, a frozen air conditioner unit, or a broken fan motor. In rare cases, the issue can be a negative contactor or a few other faulty elements.
