Condenser Fan Motor Run Capacitor

Wiring an air conditioner condenser run capacitor compared to a heat pump condenser run capacitor additionally air conditioners and heat pumps are different in certain ways.

Condenser fan motor run capacitor.

A dual capacitor has three connections herm fan and com. To inspect the capacitor make sure it is discharged. Without that boost of power the fan motor is unable to start. Delivering torque to the fan motor if the capacitor is faulty there won t be enough power delivered and the blower wheel fan belt and other important components can cease to operate.

Next measure the amperage on the wire leading from herm to start on the compressor i e. Either one of them must be on the fan port and the other on the common port along with one wire from the condenser. I followed the 2 wires from the fan and switched them. Commercial duty shaft up down motor features higher starting torque cooler running temperature and reversing plug.

I pulled the dual capacitor out and found the wires had been connected wrong. Use the equation below to verify the size of the capacitor. The capacitor helps the fan motor run. With the condensing unit operating under a load you will need to measure the total volts between the herm and common terminals on the run capacitor i e.

1 4 hp condenser fan motor permanent split capacitor 1075 nameplate rpm 208 230 voltage frame 48yz. Coleman air conditioner run capacitor 1499 5631 fits 679 6537 6535a 32 45 23 45. That s why when the capacitor stops working so too does the air conditioner. The air conditioner condenser will usually only run in the summer.

Herm connects to the hermetically sealed compressor. Fan connects to the condenser fan motor. It plays a vital role in starting up your ac. I guessed the capacitor was bad but it turned out it was good.

While the heat pump condenser will run in the summer and the winter. The start capacitor is a cylindrical component that supplies the electric charge that starts the condenser fan motor. Below are the available coleman fan motors and capacitors to work with the coleman mach product line.
