The lid lock now completes a circuit from J7 pins 1
to 2 at the control board. The control will be able to
activate the drive motor for spin. If the lid lock fails
to complete the drive motor circuit, 120 VAC will be
present at control board J7 pins 1 to 2.
The lid will remain locked until the end of the spin
cycle and the control board has received 0 rpm
feedback from the motor Hall sensor. The control will
then unlock the lid by energizing the lock solenoid
through pin 7 to 6.
