This may not be an easy one to fix "online."
First, disconnect the three motor wires and check them with your ohm meter.
You should have three readings, from green to black, from green to white, and from black to white.
The lowest reading added to the medium reading should equal the highest reading.
Also check from the motor frame to the motor wires.
Post your results, please.
The lowest reading pair will be your run winding and your medium reading pair will be your start winding.
The wire not involved with the highest reading will be the common. The common will be connected to the wall plug
The run will be connected to high and the start will be connected to the capacitor.
Post as you go if this is not clear to you.🙂
