Condenser Fan Motor Inside the Condenser

The condensing unit fan is responsible for pulling air through coils of the condensing unit. They pull air through the condensing unit coils. It runs the gamut in horsepower ratings from low fractional horsepower in small residential units all the way up to 1 horsepower (and larger) 3 phase motors in large commercial HVAC units. It is usually direct drive to a propeller blade which creates the air flow. Its job it to move air. A specific quantity of air through the condensing unit coils so that a heat exchange process can take place and rig the condensing unit of the heat it absorbed indoors or in the case of the heat pump in heating mode to absorb heat from the outside air and send it inside. It is the process of refrigeration and all the components work together to achieve one result and that is to move heat from one place to another.

Air Conditioning Maintenance & Repair

Bad Air Conditioner Blower Motor or Condenser Fan Motor

Labor (troubleshooting and repair of the air conditioner system) time (approximate): 1 1/2 to 3 hours depending on unit location and part availability

Air Conditioning Maintenance & Repair - MotorsAir Conditioning Maintenance & Repair – This is common in the summer. High heat and constant use causes old (and some new) air conditioner blower motors or condenser fan motors to burn up. There are several different types of air conditioner motors and when dealing with anything electrical the best replacement is an exact replacement. There is a contradiction to that phrase. If you have a shaded pole air conditioner blower motor in your air handler I recommend that it be replaced with a PSC motor. If you don’t know what that terminology means, the air conditioner technician should know. PSC motors are far more efficient for air handler blower motor applications than shaded pole motors. Shaded pole air conditioner motors are a rare find (at least for me) but when they are found in blowers they should be replaced with PSC motors. Additionally, when replacing any PSC motor I recommend replacing the capacitor.
