A kinked refrigerant line or a blower fan that isn t running right can cause this too.

Central air blower fan not working.

The first is an inspection of the outdoor unit to physically see if the fan is turning. Another common and easily remedied situation that sometimes results in a central air conditioner fan not working is a dirty clogged air filter. If you have your system inspected and cleaned annually it should run without any trouble. 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.

A capacitor stores up energy that provides power to your air conditioner s fans. One on either side of the motor. The circulation fan motor has two fan blades. Replace any broken fans if you are experiencing a decrease in airflow your ac blower might be to blame.

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

Next check the air handler. 5 common reasons why your central air conditioner fan is not working. The condenser lines should be cold and the air inside the home should be cool. If the blower motor fails to start nothing happens.

Located inside the air handler this fan is responsible for pushing the cold air through the ducts. Central air conditioners can work for years without problems if properly maintained and serviced annually. On the other side the fan blade directs the air over the evaporator coil. The blower motor starts turning fan blades that circulate cold air from the evaporator coils through the home s ductwork and into each room.

If the coil froze the fan could be working but the air wont go through the ice until it melts. If the fan isn t working that can cause the coil to freeze. Feel for air coming out of the vents. On one side the fan blade draws in outside air o ver the condensing coil to dissipate the heat.

Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner. If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit. Air filter is blocked.
