How To Read A Ceiling Fan Capacitor. Ceiling Fan Capacitors - Diagnosis Replacement. To read a large capacitor first find the capacitance value which will be a number or a number range most commonly followed by µF M or FD.
To test the capacitor connect it it to multi meter putting it in resistance modeA good capacitor will show zero resistance initially and slowly the needle moves towards infinityIf needle gets stuck at zero it is shorted and it shows infinity from the start it is open. First of all switch off your main circuit breaker to do safe from electrical accidents. Look the capacitor connection how the color of wire is used in fan.
Then look for a tolerance value typically listed.
Look the capacitor connection how the color of wire is used in fan. You want to make sure that the capacitor is totally discharged. In the above diagram i shown AC supply and i connect the neutral wire to motor winding common winding point and the phase Hot wire connect to the one way switch and form switch connect to the motor main winding and capacitor all wires of capacitance which is 45 uF 4 uF and 6 micro farad.
