If the jack is 1/2" from the top, unplug it at the motor, pull harness plug on the control box, make a wire jumper and short between "Fill & +" on the harness reading the locations on the control box plug. Your coach should air up. To dump air short between "Dump and +". Unplugging the control should also disable the alarm. At least that was the way we did it on our 2006 in 2008. If it's just spinning, sorry probably shot. Do not break the factory seal and open the motor case as any action will not be in your favor at Atwood. Opened one of our's and it was a $700 peek at busted nuts on 2 threaded shafts. They replaced one no charge a year later that wasn't opened. We've had 3 of 4 fail in the 1st 5 years of ownership. I believe this info is found on the troubleshooting pages for the Levelegs.
