Here is some more information,
Tested and found 120v from Black to Gray, when reversed I have 120V form Black to White. This should be correct. I put a clamp on Amp probe on it and it is pulling .6amp while the motor is humming. I believe this his should indicate that the board is not failing under load. But I could be wrong.
I took a pin and turned the motor by hand and it does turn freely. 3 motors all do the same thing. I took the original motor , cut the wires and hardwired it to a cord. Black is the common so I connected to the N , I connected the white white wire to Hot and it just hummed, will not turn. Strange very strange
Okay so the customer called me and said his friend who works for a big national store was at his house this weekend. This gentleman said I have no idea what I am doing and the main control board needs to be rewired. He told the homeowner that the dispenser uses a dual neutral control and you have to remove one of the neutral wires to work with the substituted main control board. ??????? What????
