I have a Whirlpool Cabrio WTW5500XW1. It fails to spin. I've replaced the shifter twice, the control board, the capacitor, and the motor and it still won't run. I have 120v at the power connector but only 60v at pins J16-5 and J16-7 while the motor is disconnected and I Jane it on low spin in Manuel test mode. Both main controls have the same readings. I've had a service tech out that knew less than I did and another on the phone. Help please!
