Central Air Fan Motor Not Working

The unit stops working.

Central air fan motor not working. If you have your system inspected and cleaned annually it should run without any. It is common for the contactor to go bad over time which restricts the outside fan from working properly. 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. When the home s thermostat detects that the living space is warmer than its programmed temperature level a cooling cycle begins.

If the compressor is working but the fan won t turn then the problem is most likely with the motor and or capacitor. Central air conditioners can work for years without problems if properly maintained and serviced annually. 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. Here s an easy way to test if the fan s capacitor is bad.

An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor. If they aren t working properly call a trained technician. Slide a long thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning. So if the capacitor attached to your fan motor is bad the fan won t start spinning.

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. The blower motor starts turning fan blades that circulate cold air. Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner. 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.

This is another part that must be repaired by a professional hvac contractor. Understanding the parts of your ac unit. While each component in a central air conditioner is critical quite simply the unit will not work if the fan is not running. But before you phone see if the problem is caused by something else.

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. Do not use any kind of conductive metal or material to do this. One common reason an ac fan motor burns out is due to dirt building up around the fan motor.
