Condenser Fan Motor
The condensing unit fanis 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.
In straight air conditioners the air conditioner fan is used mainly in the summer or when the air conditioner is running. During the winter this fan sits idle until the air conditioner is turned back on in the spring when temperatures begin to rise.This can be a problem for the air conditioner motor. Sitting all winter without any motion the bearings and shaft in the air conditioner motor can seize up or rust. It is important that the air conditioner motor be checked to ensure it is running especially when it is first turned on after sitting idle all winter. This is a good reason to have air conditioning spring maintenance performed by a professional.
