AC fan not working

Why is my AC fan not working and how can I fix it?

The most probable causes due to which the AC fan stops working completely or starts functioning abruptly are listed below. Let’s find them out:

Problem 1: The fan isn’t spinning and you can’t hear the compressor

Start by turning on your air conditioning before going outside to the compressor outside your house and listening. The compressor should still be audible even if the fan isn’t operating. The fan is not the issue if you hear nothing. There is no power flowing to your compressor. This can be a problem with a contactor or a circuit breaker.

How to fix it:

  • The AC should first be turned off inside.
  • Next, go over to the circuit breaker.
  • Then, start searching for a switch that says “HVAC,” “furnace,” “AC,” or “compressor.”
  • If the switch is off, try turning it back on, then walk inside and test the air conditioning once again.
  • In the event that the switch is already on when you check it, turn it off, wait a little while, then turn it back on and test the AC.
  • Check out the compressor outside. If you still don’t hear anything, the contactor may be malfunctioning.

Alternate method:

The power flow to your compressor unit is controlled by the contactor. Your compressor isn’t receiving electricity, which is explainable if it’s broken.

Checking the voltage of the contactor is the only method to confirm if this is the issue. This is not a task for newcomers. If you’re not an expert HVAC technician, ask someone who is to look at your system.

Problem 2: The fan is not spinning at all despite the compressor being operational

If the fan isn’t spinning at all but you can hear the compressor humming, a faulty capacitor is probably to cause. The fan is ignited by the capacitor. As you can see, once the fan is working, it uses very little electricity. But it takes a lot of energy to start the fan. Until the capacitor utilizes this energy to turn on the fan, it stores it up like a battery.

How to fix it:

  • Try to “kick-start” the fan to see if the capacitor is the issue.
  • To fit through the fan grate, you’ll need a long stick of wood or another non-conductive substance.
  • But first, make sure the air conditioner is on and set to run. Then, attempt to push the fan with the stick so that it spins vigorously.
  • If the capacitor is the issue, this ought should be sufficient to get the fan spinning.
  • Call an HVAC professional to replace your capacitor if it begins this way.

No matter how vigorously you spin the fan, if it won’t turn on, there must be another issue.

Alternate method:

When the compressor is operating and the fan won’t turn on at all, the fan motor probably has damaging issues. This is more frequent with poorly-maintenance systems or with systems that run in environments where a lot of dust and debris flow with the wind. You can only fix a defective motor by replacing it. However, this is pricey, so make sure you first check out all the other possibilities on our list.

Then, to certain that this is the issue, have a reliable HVAC specialist examine it. Additionally, if your HVAC system is more than ten years old, it could be wiser to replace it entirely.

Problem 3: Slow rotation of the fan

Your fan spinning slowly is the next problem. This symptom could appear while the fan is trying to start up or when your system is operating.

How to fix it:

Checking your air filter is the easiest remedy in this situation. Sadly, many homeowners and renters are not aware that they need to check this often. Your system’s airflow is essentially facing obstruction by an air filter that has clogging. The fan will be under stress as a result, and it can burn out or operate slowly.

If you are unsure about how to check the air filter, you can watch a Youtube video of the same or just google it to make the process simpler and easier. Hop on to our next fix if this isn’t the issue.

Problem 4: Slow but loud rotation of the fan

The next situation is when your fan slowly spins while making a loud noise as if it were grinding against something. Again, if you try to kick-start the fan, you could observe this. This most likely indicates that a piece of debris or another object is blocking the fan.

How to fix it:

  • Disconnect the AC from the thermostat and the circuit breaker.
  • Verify the fan for any particles or other objects it may be coming into touch with while spinning.
  • It is simpler to manually rotate the fan using your kick-start stick.
  • If you see any debris, clean it out, switch everything back on, and listen to it once again while it runs.
  • However, if this doesn’t resolve the issue or you can see that the fan is making contact with another component, contact an HVAC specialist to fix it.

Problem 5: The fan/system switches on and off randomly

Regardless of your thermostat settings, does your fan or system keep randomly turning on or off? Even the electrical clicking sound of the device turning on and off could be audible.

How to fix it:

There is almost certainly a problem with the system’s electrical wiring, control board, or another electrical part. To properly identify and resolve the issue, contact an HVAC repair specialist.
