Central Air Fan Motor Not Working

Do not use any kind of conductive metal or material to do this.

Central air fan motor not working.

If they aren t working properly call a trained technician. But before you phone see if the problem is caused by something else. 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. An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor.

Central air conditioners can work for years without problems if properly maintained and serviced annually. However you can prevent it from burning out sooner than intended with regular hvac maintenance. When the home s thermostat detects that the living space is warmer than its programmed temperature level a cooling cycle begins. One common reason an ac fan motor burns out is due to dirt building up around the fan motor.

So if the capacitor attached to your fan motor is bad the fan won t start spinning. Here s an easy way to test if the fan s capacitor is bad. While each component in a central air conditioner is critical quite simply the unit will not work if the fan is not running. 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.

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. It is common for the contactor to go bad over time which restricts the outside fan from working properly. The blower motor starts turning fan blades that circulate cold air. 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.

Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner. Contactor problems can result in your central air conditioner fan not working if you re unsure as to what your air conditioner s contactor switch is it s a switch located on the inside of your unit that ensures that there is enough voltage being provided to control the compressor as well as the condenser fan motor. If the compressor is working but the fan won t turn then the problem is most likely with the motor and or capacitor. Slide a long thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning.

Understanding the parts of your ac unit. 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. Another common and easily remedied situation that sometimes results in a central air conditioner fan not working is a dirty clogged air filter.
