Ok, when checking hall sensor voltages on the board per the training manual, I was getting around 15VDC on connector J1001, which seemed a bit high since they say anywhere from 0VDC-12VDC.
I pulled the motor off to access the hall sensor and it looked like it wasnt seated too well. I reseated it and reinstalled the motor.
When doing the agitate test in service mode, the lid locks and the tub agitates normally.
When doing the spin test in service mode, the lid will NOT lock at all and the spin test does not begin.
Likely the hall sensor based on these tests?
