Blower Wheel 5304404774

If your air conditioner is making an unusual noise, the problem could be with the blower wheel, or its fans. The motorized fan in an air conditioner pulls air through the filter and over the cold evaporator coils and then re-circulates the cooled air back into the room. There is also a second fan on the motor shaft that cools the condenser coils at the back. An unusual noise is usually due to the fans striking the inside of the air conditioner. Check your blower wheel, and the fan blades for physical damage, dust, and signs that they have been hitting something during the cooling process. If the wheel is damaged and the unit is not working properly because of it, replace the part right away. Remember, the power should be disconnected from the air conditioner before you perform this repair.
