The switch you’re looking for should say something like “HVAC,” “furnace,” “AC,” or “compressor.” Solution 1įirst, go inside and turn off the AC. This could be a circuit breaker issue or a faulty contactor. Your compressor isn’t receiving any electricity. If you hear nothing, the fan isn’t the problem. Even if the fan isn’t working, you should still hear the hum of the compressor. Scenario 1: Fan Isn’t Spinning and You Can’t Hear the Compressorįirst, turn on your air conditioning, head out to the compressor unit outside your home, and listen. Simply follow these AC fan troubleshooting steps to get your cold air flowing again ASAP. Using this checklist, you should be able to check for/diagnose the symptoms of your malfunctioning AC fan.
