Central Air Fan Motor Not Working

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.

Central air fan motor not working.

This is another part that must be repaired by a professional hvac contractor. 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. Understanding the parts of your ac unit. Another common and easily remedied situation that sometimes results in a central air conditioner fan not working is a dirty clogged air filter.

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. The blower motor starts turning fan blades that circulate cold air. 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.

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. The unit stops working. Slide a long thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning. 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.

If they aren t working properly call a trained technician. Here s an easy way to test if the fan s capacitor is bad. It is common for the contactor to go bad over time which restricts the outside fan from working properly. One common reason an ac fan motor burns out is due to dirt building up around the fan motor.

Do not use any kind of conductive metal or material to do this. 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. When the home s thermostat detects that the living space is warmer than its programmed temperature level a cooling cycle begins.

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. An air conditioner contactor is an electrical switch that controls the compressor and condenser fan motor.
