3 wire dehumidifier fan wiring ?

[jteneyck]

I tore apart a non-functioning LG dehumidifier and kept the fan motor in hopes it might be adaptable to another unit that works fine except for the fan, which I cannot find a replacement for.  Make sense?  Anyway, the fan motor has 3 wires, red, yellow, and black, yellow and red on one side of the coil and black on the other.  All have continuity to the others.  

I'm wondering if one of the wires goes to a capacitor, which I foolishly didn't think about when I tore it apart and then disposed of.  Does anyone have insight into how these motors need to be wired?  The fan in the other dehumidifier is a simple 2 wire plus ground that even I can understand.  Thanks in advance.

Now that I think about it, the dehumidifier had a high/low feature so maybe it's a two-speed fan.

Google the model and see if there is a you tube

If THIS is the motor, yes it has a capacitor. The image says 6uf 250v.  Roly

It looks like this:



The label on the side:



It's pretty close to this one:



Can't find a wiring diagram, however.

Two speeds? Speed A is red hot, Speed B is yellow hot? It i cannot imagine red and yellow would both have continuity of so... would they?

That little shaded pole motor shouldn’t require a capacitor. 

Measuring resistance, highest pair should be high speed, lowest pair is hi to low and middle reading should be low. Make sure you cap an unused connection as it will be energized. Only connect one speed tap at a time.

Right you were, as pretty much always.  Thanks very much.
