Troubleshooting of Ceiling Fan Capacitor
Troubleshooting of Ceiling Fan Capacitor Most ceiling fans use a type of motor known as a “permanent split capacitor motor”. These motors have two coils, a “start” and a “run” winding. A fan capacitor is connected in series with the start winding to insert a phase shift, but once the motor is up to speed it becomes an auxiliary winding. In order to reverse the motor, the capacitor is applied to the “run” winding which then beco...
