I just took apart an old dishwasher for parts. The large motor I got from it seems to be an induction motor. It has 4 wires. Green, yellow, red, and blue. I know for a fact that the green one is ground, so it can be ignored. It also had a 15uF capacitor for the motor, but I'm not sure how it was connected. The dishwasher is at a different house so I can't look now, but if I need to know how the cap was connected I could look next time I'm there. How can I figure out how to wire this motor? In case this helps, it is model 5kcp122e1bx, but I can't find much info about it online.
I just measured the resistance between the leads. blue to red is 16 ohms, blue to yellow is 4 ohms and yellow to red is 20 ohms. 16+4 = 20, so that means there isnt really a winding between the yellow and red. This makes me pretty sure that blue is a common, red is main coil and yellow is a start coil. That is what I would have guessed just looking at the wire colors. But having a second differently sized start coil, wouldnt that usually mean that the motor is resistive start and doesnt use a capacitor? I guess I am wrong as i obviosly has a capacitor. So how do I wire it up? Thanks!
