motor giving problems

[Les Jones 1Participant @lesjones1]

It could also be the centrifugal switch. When you remove the wires from the capacitor measure the resistance between the wires that you removed from the capacitor. If the centrifugal switch is closed (Which it should be when the motor is stopped.) you should get a reading of about 10 to 20 ohms. this will be the resistance of the main winding in series with the start winding and the centrifugal switch. If you get a high reading then the centrifugal switch is not switching in the start winding and start capacitor. (An open circuit start winding would also give a high reading but it is not very likely to be the start winding.)

To avoid confusion – the marking for the spec of the capacitor (500v, etc) tells you what to re-order, but this is not the voltage at which the capacitor is run in this example, or the voltage it may hold when switched off.

There is usually a margin of safety in such devices.

Cheers, Tim
