Feel for air coming out of the vents. The condenser lines should be cold and the air inside the home should be cool. A kinked refrigerant line or a blower fan that isn t running right can cause this too. On the other side the fan blade directs the air over the evaporator coil.

Central air conditioners can work for years without problems if properly maintained and serviced annually. Symptoms of a central a c fan not working there are a few ways to tell if your a c fan is temporarily or permanently out of order. Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner. If you have your system inspected and cleaned annually it should run without any trouble.

The circulation fan motor has two fan blades. If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit. One on either side of the motor. If the blower motor fails to start nothing happens.

If the coil froze the fan could be working but the air wont go through the ice until it melts. Next check the air handler. However your capacitor can go bad for various reasons and stop working properly which will force one of your system s fans to stop spinning. 5 common reasons why your central air conditioner fan is not working.

Air filter is blocked. This would indicate that the thermostat and the blower motor are operating but the refrigeration system outdoor compressor is not working right or air isn t circulating properly usually because of dirty filters.

When the blades are covered with an excessive amount of dust or the blower motor is broken you will have issues with your system. But before you phone see if the problem is caused by something else.
