Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor or a run capacitor. Some motors will even use both.

Capacitors like this are used to start a variety of electric motors. I had the capacitor in the blower motor of my AC unit go bad. Nothing beats analog.

The run capacitor limits the current that will pass through the start winding when the motor is running, because they are wired in series. The run capacitor also provides running torque when the motor ...
