When u opened the jack release did u stop when u felt pressure. Try to go past this pressure with your hand NO PLIERS. When mine did this I felt pressure and thought that this was the limit and didnt want to damage anything. Nothing happened. I new that it should release if opened. I went back and turned with more force and bam they retracted. sent controller back tp HWH they did a quick turnaround and have not had another problem Knock on whatever helps. I felt resistance on the release but I applied a LITTLE more and I was able to turn it several more turns and it allowed the jacks to retract. Good luck Larry

The jacks indicate down (red lights all on). I have not added fluid lately, but it was serviced when we bought the unit last fall, and we have only used it a couple of times so far--once for a week over the July 4th holiday, and once now. There was an issue with sluggish operation over the 4th, but that seemed to resolve when we replaced all three house batteries. I know they work fine, because we've been using them the last few days--and the Hurricane water heater system now also works. I had gotten a low-voltage warning before, which is how I came to know my house batteries were bad. I called Hurricane customer service, and we ran through the troubleshooting procedure. The fellow told me to check the house batteries, and indeed they were bad. Once I had new ones installed, the water heater works fine.
Anyway, I am quite sure I have decent voltage--after all, the jacks extend just fine. It's just that they won't retract. But rebe462 is correct in that the jacks SHOULD retract when the manual values are opened on the solenoids. But for the life of me, they don't. I just do not understand it yet. I don't know how much time they should require to go up when the valves are open, but we had the valves open for at least 10 minutes (if not 15), minimum. The jacks didn't seem to move at all...even when I tried to nudge them along a bit, by dumping some air to put weight on them.

Thanks Larry...
No, I fully opened them, to about 5-6 turns--until they got hard to turn again. There are internal springs that you have to overcome, according to the manual, and I am quite sure I did this. They are pretty stiff at first, but then get easy. Then after about 6 turns, I ran them back against the stops. The 'T' handle is gone from one of the solenoids (for the left rear jack), so I had to use a needle-nose vise-grip on this; but I ran that one out only after the others had been run out by hand. And I ran it out about as far, judging by visual inspection of the unit.
I carry two 4X4 blocks because I never know when I will need one of two. I have had one jacks stick and have done what I suggest you do. I have never had all 4 jacks not retract. I have frozen a couple in place and had to break them loose to retract.[

Interesting idea, but I don't have a pry bar. And, the base in the parking spot is a gravel/sand mix, so I don't know what you'd pry against. I am actually glad it is softer, because it gave and let the jack pads sink when I dumped a bit of air pressure and let the coach settle onto the jacks with the solenoid valves turned into the manual RETRACT position. At least I didn't break anything. But I was thinking along those lines as well, which is why I tried to dump some pressure onto the jacks. Didn't work though.
Why would ALL jacks be stuck though? There has to be some sort of safety relay that isn't telling the jacks it's OK to start retracting. Something like that. I'll go through the schematics again, but just having the diagram doesn't mean I know what the individual components are tasked to do. So I think I am stuck at this point--until I talk to someone tomorrow morning.
Thanks for the posts so far guys. It's very comforting to at least know that I have thought of the things you guys have suggested. So the posts are much-appreciated...

I would suggest you probably have a stuck shuttle valve. The valve is located on the top of the pump and sometimes some light tapping with a hammer will get the valve to move.

Yes, I also believe that's what the problem is. Another fellow on a different forum reports having had the same issue. I will call Winnebago in 30 minutes, and hopefully they will be able to tell me where exactly on my coach that the shuttle valve is. With any luck, I can be back on the road within a few hours.
If you have emergency road service call them and say you want to be towed. Say "by the way" the jacks are down and must be raised to tow.
Friend of mine had a frozen key and could not turn the key to start. Big wrecker arrived with a locksmith as a passanger who solved the problem.
BTW- I carry a sharpened 2x4 and short 4x4 block to push a weak jack back up. Also could jacks be stuck in soft gravel? Know that they can freeze to the ground in the winter.
With what you have done jacks should come up-understand the fustration!
Just a thought. You said that your Jacks Sank down some in the Dirt and Gravel mix. How far down did they in fact sink ? Maybe they sank just enoought to be putting a Bind of the Jacks. Have you tried to remove some of the Dirt and Gravel on the side of the pads that needs to lift up in the correct direction. Maybe your sunk just enough to keep them from retracting. Pretty simple to find out by removing some material out of the way and try again. Good Luck. Happy Travels. Dan & Jill
The right front jack was down about an inch or so, and the left front jack was down about a half inch. The aft jacks were sitting on top of the gravel.
The problem is resolved--it was indeed a stuck shuttle valve. After unsuccessfully getting it to release by tapping around on the manifold itself, HWH had me take out one of the brass plugs on top of the manifold. This relieved the pressure, and the jacks came up. I delivered the coach to Winnebago, and all is well.
Thanks to all who posted in this thread. The input was both reassuring and helpful, and helped me make a difficult decision. So it was much-appreciated.
