Perhaps one of the more head-scratching moments for any Argyle, TX homeowner is when they realize their AC unit fan isn’t spinning, even though the unit itself appears to be running like normal. Ugh — how can this be? Cool air flowed through every vent only 20 minutes earlier, and now you and your family are left to sweat it out until the problem is fixed.

 

But that’s just the thing — what exactly is causing the AC unit fan to be stuck in neutral?

 

Today’s article will explore a few possible reasons for an AC unit fan not spinning. It could be something as simple as a circuit breaker issue or a bit more complicated and require help from your friendly neighborhood AC repair guy. But either way, you won’t have to go without a properly working air conditioner for very long if you call A&A Air.

 

Why Is Your AC Fan Not Spinning? It Could Be One of these 5 Reasons

 

The AC unit fan’s purpose is to help remove hot air from your home by working in conjunction with the AC fan motor inside the house. If one or both fans aren’t working, lukewarm air will begin blowing into your home.

 

Below are a few reasons why this may have happened:

 

1. A power breaker issue — The AC unit fan will stop spinning if the house experiences an electrical surge or the air conditioner system overheats and trips the circuit breaker. The fix should be as simple as walking over to the electrical box (likely located on a wall inside your garage), locating the tripped breaker, and resetting it. The only problem is if the circuit breaker continues to trip after you’ve reset it. If this happens, call A&A Air. 

 

2. Defective capacitor — Many people assume that AC units only have one capacitor to transmit energy signals to power the entire AC unit, including the fan. But this isn’t the case, as different capacitors deliver power throughout the system. If a capacitor is old or damaged, the AC unit fan will stop spinning until an HVAC contractor can professionally replace it. 

 

3. The fan motor burned out — If you’re wondering why is my AC unit fan not spinning, it could be that the fan motor is burned out and needs to be replaced. Fan motors aren’t meant to last forever, but with routine preventative maintenance, there’s no reason to believe your AC unit won’t continue to work properly for many more years to come.

4. Clogged air filter — Air filters remove dust, dirt, pollen, pet dander, and other particles to keep your home’s air clean and safe to breathe. They also ensure that critical airflow cycles to and from your air conditioner to keep your home comfortable year-round. Clogged air filters force the unit to work significantly harder and can lead to other problems, such as AC unit fans not spinning. Most air filter manufacturers like General Electric, Filtrete, HEPA, and Honeywell and HVAC companies recommend changing your air filter every three months. But a lot of that depends on the size and quality of your air filter.



5. Contactor issues — An AC unit fan not spinning could also be because of a problem with the compressor’s contactor switches. Especially if the switches are worn out and have broken over time. The compressor is the heartbeat of your air conditioner, and it is possible that the unit’s compressor switch is no longer sending adequate electricity to the AC unit fan and condenser unit.
