Microwave wiring for fan motor

It's a remote possibility!

Jamie

Would there be a capacitor as well ? (for the greys)

I Would expert that the white wire is neutral , the black wire is hot, and the green wire is ground. I can not tell from the photo if the white and black wire go to the same place, so could easily be wrong.

Red is fused so looks like a good candidate for hot, green has a ring terminal, typical of earth wires, white+black thus must be neutral so that much sounds good.

It could be a tapped motor coil used as an autotransformer to power a low-voltage (eg: 20V) gearmotor to drive the platter. In which case the greys are the low voltage

How about taking some resistance readings between all of the leads?

sounds right The pcb is quite clear, red/white hot/neutral, through a LC filter then a fuse. y-capacitors to green ground

Thanks for all the responses.

I looked again at the motor itself.

I don't think the circuit board has nothing to do with the fan motor.

There are only two gray wires going to the motor.

Gray wires are 300V 22 AWG

Motor has sticker with this info

Oh Sung Oem 10DWX1-B07 120 V .3 amps MAX Z.P. M1104151

Does it look like I could hook up a cord to the grey wires temporarily to see if the motor works ?

Thanks, Andy

Yeah, it's just a crummy little impedance limited shaded pole motor, all it needs is voltage 120VAC. The little board is mounted there for convenience and is some power entry stuff like fuse and EMI filter for the whole oven.

Thanks.

Sure noticed a ton of spam here in just one day.

I want to cover the coil since it has 120 V going thru it.

Is it designed for air flow to go over it.

I could put a wood cover around it ?

Thanks.

If it to be cooled, I think it would be best to make a little sheet metal box with perforated holes in it, so that it can breath.. You should be able to find that at a hardware store. The holes are sized for pop rivets. with that you can fab a little cover and pop rivet it together.

Look for "Perforated Sheet Metal"

Thanks,

I think I will get one of those plastic project boxes with the rubber gaskets and drill some holes in it for ventilation.
