Fixing A Broken Air Conditioner Fan Motor

The fan motor helps your air conditioning system maintain the right internal pressure and temperature. It's a very important part; when it breaks, your air conditioner will stop running.

Check Your Air Conditioner Fan Motor

Both the indoor and outdoor units of your AC system have fan motors that move air through your air conditioner to keep the refrigerant at the proper temperature and pressure. If the motors stop working, the unit won't run.

Fan motor failures in the indoor unit aren't good, but if the motor in your compressor fails, you're in hot water — that’s the equivalent of blowing the engine in your car. You'll need to get it replaced before your unit will run again.

How to check for a broken air conditioner fan motor

  • Make sure the thermostat is on cool mode. Set the temperature 5℉ lower than the actual indoor temperature.

  • Check the circuit breakers and the outdoor disconnect to make sure there's power going to the system. The outdoor disconnect is typically mounted on the wall at the outdoor unit. It allows the technician to disconnect power to the unit for servicing. If there's an external on/off handle make sure it is in the "On" position. If it's not, you're dealing with a tripped breaker.

  • If the contacts inside the contactor are worn, they will not allow the condensor to run.

  • See if the condensate pump is plugged in to a working outlet. If the GFCI has tripped, reset it.

  • Listen to your AC system by unplugging it for 15 seconds then plugging it back in. Then, hold down the reset button for three seconds, then release. Once it's restarted, listen to the sound.

    As it runs, a noise may develop. Is it high pitched? This sound indicates that your AC isn't getting enough airflow through the return vents and ductwork. The issue may be a loose fan bolt on the condensing unit.

If the air conditioner fan motor is the problem, keep reading. If not, you can investigate other AC issues.

What To Do If Your Air Conditioner Fan Motor Is Broken

When the fan motor breaks, your air conditioning system is unable to run. It's time to get the fan motor replaced. You'll want to contact a professional to come and help with the repair.
