When I use the switch on the front of the coach to raise or lower my landing gear, I can hear the pump working but nothing happens until, I believe the circuit breaker trips shortly. I have a 6 point leveling system and can operate the landing gear with it with no issues. We are getting ready to leave for 6 to 8 months and I would rather not take it to my dealer that is quit a distance away. Hoping someone has experienced this and knows what the trouble is.
