Signs of Fan Motor Problems with Your AC

With summer in full gear here in Wilsonville, OR, you need to be extra vigilant to detect any potential problems with your air conditioner. A sudden breakdown could leave you in the lurch just when the temperatures are really soaring, and in many cases, that could prove a health risk as well as any other concerns. The more you know about potential problems with your AC, the more quickly you can respond.

A Common Problem

Among the most common calls we get is trouble with the fan motor: the component that turns the fan off and on, and which can create a huge number of problems if it’s malfunctioning. Without it, the cool air won’t get blown into your home, leaving your air conditioner all but useless. Even more worrisome, that cool air could create ice on your coils and cause other problems in the system that could affect additional components beyond the fan motor. Signs of fan motor problems can include, but are not limited to the following:

  • The exhaust fan blowing outside, but no air moving inside.
  • Buzzing or grinding noises as the motor struggles to function.
  • Electrical issues, such as the circuit breaker shutting off power to the unit.
  • Frost or ice forming on the coils inside the air conditioner.


If you suspect that the fan motor is the problem. Shut off power to the air conditioner and try to turn the motor by hand. If it won’t go, don’t force it, just call in an air conditioning repair service. If the power shuts off unexpectedly, check the breaker box to see if the switch has been triggered. If it has, reset it sand run the AC again, If the same thing happens, call in a repair service immediately.

A fan motor is nothing that an amateur should try to repair. Instead, call in Clean Air Act, Inc. to do the job right!
