To all - Thanks - Problem fixed!!!! I won't bore you with all the things that I spent four hours today trying to do to fix the problem, but just as I was about to give up in frustration, I tried one more thing and it worked! I don't know why exactly it worked, but it did work and I'll take it and run! I will tell you what worked first and then if your interested you can read what didn't work in my situation. When I left yesterday, my coach was in storage, in a ready to travel status with air bags inflated, but jacks extended to within 6 inches of the ground and front slides and jacks would not work or move. When I arrived to day, I found the coach air bags had deflated and the jacks were touching the ground. I figure the air escaped because the jacks were extended. Here is picture of a hydraulic unit similar to mine:
This unit has four override valves, mine has five. What I did in frustration and as a last ditch effort was to take a flat screw driver and turn all of the override screw closed. I then took the two red direction valves (not noted on the diagram) and pulled them out and turn them half a turn to lock them open. I then went in to the Motorhome and turned on the display and tried to retract the jacks. Nothing happen. I went back out and opened the five screw (back to original position) and returned the red directional valves to their original position. I then went in an tried to operate the display key pad and to my amazement I heard the jacks being retracted. I then tried the front two slides and they both worked. Why this worked I can only guess, but I think there was to much air in the system and that was why it didn't respond, so when I closed the override screw and open the red directional valves, it must have broken the air lock. I will stay with that until someone offers a more technical analysis.
So what did not work that I tried:
1-disconnecting the negative terminals on all of the batteries
2-disconnecting all of the electrical connections to the hydraulic unit and the module
3-trying to reset the command display by either pushing all four up or down arrows at the same time and hold them for a period of time.
4- trying to Nil the command display to think everything was level.
5-looking everywhere for a tripped breaker. I did find the breaker in behind the chassis batteries on the left side, but the little ear tag was not out.
Over the four hours I tried the above things many times in various sequences. I also went to the dealer and looked at another 2011 unit with the Service people to see I was looking in the right places and to see what the circuit breaker for the hydraulic unit looked like. They did give me a service sheet for the unit and how to purge the air of it, but that was only applicable if the jacks and slides were retracted. They said if I succeed to let them know how I did it. Will make that visit tomorrow!
