Central Air Fan Motor Not Working

One common reason an ac fan motor burns out is due to dirt building up around the fan motor.

If they aren t working properly call a trained technician. Additionally if the capacitor is shared by the ac compressor as in the case of a dual capacitor your unit may experience further damage since the compressor may overheat. Here s an easy way to test if the fan s capacitor is bad. Do not use any kind of conductive metal or material to do this.

If you don t hear any sounds to indicate that the compressor is working and the fan isn t spinning the most common causes are a lack of power or a faulty compressor contactor. Another common and easily remedied situation that sometimes results in a central air conditioner fan not working is a dirty clogged air filter. When the home s thermostat detects that the living space is warmer than its programmed temperature level a cooling cycle begins. It is common for the contactor to go bad over time which restricts the outside fan from working properly.

Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner. Central air conditioners can work for years without problems if properly maintained and serviced annually. An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor. If you have your system inspected and cleaned annually it should run without any.

As mentioned previously the fan motor is one of the hardest working components in your air conditioner and wear and tear will eventually take its toll. Understanding the parts of your ac unit. This is another part that must be repaired by a professional hvac contractor. So if the capacitor attached to your fan motor is bad the fan won t start spinning.

However you can prevent it from burning out sooner than intended with regular hvac maintenance. Slide a long thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning. Fans in the central a c both pull air out of the room to be conditioned and have humidity removed and also push chilled air through the vents throughout the house. The unit stops working.

If the compressor is working but the fan won t turn then the problem is most likely with the motor and or capacitor. If an ac unit continues running with a bad capacitor your fan motor will have to work much harder resulting in your motor burning out completely over time. But before you phone see if the problem is caused by something else.
