What does an AC fan motor do?
What is an AC Fan Motor? The air conditioner fan motor drives the AC fan, which blows air in and out of the house. This is important for moving hot air to the outside of the building, as well as blowing cool air through the ductwork and into the rooms.
Is there a capacitor in the fan motor?
The fan motor does not contain the capacitor as I say in the video. It is a separate part that looks like a cylinder in the side of the unit. It contains a high voltage so be careful with it. The capacitor will have power in it even with the power shut off to the AC unit. Always turn off the power before resetting the air conditioner.
Why do I need an electric engine cooling fan?
Usually, electric fans will activate shortly after the air conditioner is turned on, this is done to dissipate the extra heat produced in the condenser while the air conditioner is in operation. Engine cooling fans are temperature controlled to only run when needed.
When do you need to replace an outdoor fan motor?

The reading should be within 10 percent of the rated capacitance on the capacitor. If the reading doesn’t match the rating, replace the capacitor. The fan motor is one of the most important components of your air conditioning system. Often referred to as the “heart” of HVAC equipment, fan motors work hard and under tough conditions for years.
Is it worth it to replace an AC fan?
Purchasing a new compressor is substantially more expensive than replacing the fan.
