It should not be the moisture sensor as it and it’s electronic control just control the advancing of the timer.
Sounds like it may be a timer problem. It is the only part that actually changes things between timed and auto cycles.
Set the unit to auto, mid cycle and then open the door to stop the unit.
Unplug the unit.

Then measure across Timer Switch 2 with a meter.
