Signs of a bad capacitor in a ceiling fan include: Fan runs slowly or not at all on all speeds, Fan will not start but will spin if started by hand, Certain speeds are slow or do not work, The motor hums and turns freely by hand but will not spin

Ceiling fan capacitors are used for fan motors that are split phase single phase. There are two windings, Starting Winding and Running Winding. Capacitor helps single phase induction motors to identify and creates second phase with auxiliary winding to produce RMF. Ceiling fan capacitors in sri lanka are used for ceiling fans, these capacitors help induction motors to identify and create rotating magnetomotive force with single phase AC supply. The capacitor creates second phase to the motor. Current leads by 45 degree, it lags 45 degree behind due to capacitance. In order to function properly resistive inductive circuit must be maintained, this is done by windings creating enough resistance and Inductive reactance, in the end all of the reactance is equal to capacitive reactance, which result in 90 degree out of phase. Ceiling fan capacitor in sri lanka mostly comes with 2 wires or 2 pins. Generally 1μF to 4.7μF CBB61 start capacitors are available in wholesale and retail capacities in our online store and in our shops in pettah.
