Im a new holland mechanic. The number one problem usually is on of the solenoids on the control valve beneath your feet under the panel. It will sometimes work then once it heats up enough from an internal short it will start clicking really fast then stop and then both solenoids will not work. Unplug one at a time until you find what one is bad. You can also test the door switch plug with a voltage reader to verify problem since it sends backfeed from the bad solenoid. Voltage will be lower than 12v and continue to drop the more the solenoid heats up. New solenoids are around 250. Hope this helps anyone!
