This is a ceiling fan I have in the bedroom.
But it stopped turning.
It has a 3 speed switch on the wall plate that also has a capacitor/resistor attached. It is marked MKP2+3NBL. It has 3 wires and the schematic on the side shows a 2micro Farad cap. with a 470k ohm resistor parallelled across it, and a 3 micro Farad cap. with a 470k ohm resistor parallelled across it.
Up at the ceiling fan I have measured 240 vAC, (in Australia, that is our domestic single phase supply). On dissasmbling the motor, I have the active and neutral going to a summer/winter reversing switch, and a 1.5 micro Farad (presumably) starting capacitor, and 4 wires into the motor casing.
Can anyone tell me what I should be able to measure across the various wires at the motor connections?
Cheers Phil
