Well Sir,
Since you don't say what make or model of jack system you have, I'm going to assume that you have an HWH system. Ours is an '04 Itasca Horizon 36GD with the C-7 330HP CAT and it came with an HWH system. So, if that's the case, your pump should run when the slides go out and back in. And, it should run when the Jacks are extended but, it should NOT run when you retract the jacks as they are spring retracted, not hydraulically retracted.

Have you had the coach long? Has this done it before, what?

It is the HHW and it is a 2005 and bought it new. When you hit the up button on the panel the pump will run but not when you hit the down button. I know that they retract with a spring,but the pump runs up and the jacks are up but they will not run down.

Wilkiesr,
Well Sir, not doubting what you're saying, just what's happening. In the HWH jack system, there is no need for the pump to run when RETRACTING the jacks. The springs do all the work. Our coach, an '04 Itasca Horizon 36GD with the C-7 330HP CAT, does NOT run the HWH pump when I'm retracting the jacks. All you hear is the sound of the hydraulic (hissing sound) oil returning to the reservoir and, an occasional "ping" from the springs readjusting their positions on the captures. So, if your pump IS SUPPOSED TO RUN while your jacks are retracting, that's a new one on me. I just don't recall before, anyone saying their pump runs in that part of the operation. It does run for both the extension and retraction OF THE SLIDES.

Is the parking brake set? The jacks won't extend unless the parking brake is engaged however if the parking brake safety switch fails or gets disconnected by accident they won't extend either.

They won't go down if you are connected to your toad. The umbilical chord must be disconnected. Also I had another brand with HWH and the switch on the parking brake pedal had the wire loose. Reconnected and Ok.

Where in the world did you read that Partner? If that were the case, absolutely NO ONE could level their coach at a campsite, while only at an over-nighter. There hundreds and hundreds of folks at campsites and RV parks as we speak, pulled in for only overnight and, they have their jacks down and, their toad IS STILL CONNECTED, tow bar, safety cables AND UMBILICAL cord.

OP,
Paul or, otherwise known as "AZ Pete" is the one to talk to about this. He's one great guy that knows every inch of every HWH system. He's on here normally so, if he don't chime in at any time soon, I'd look up his user name and, send him a message.

HWH troubleshooting guide isvery good. If you don't have hard copy its available online.
Guess wpuld be brake safety sw problem but pump running for retract is a baffler???

[NeilV]

They put double acting jacks in the 2005 Adventurer? Every 05 I was in a relief valve allowed the jacks to retract without running the pump or you pressed the common store button to retract all of them at once. I don't want to appear insulting however I sometimes get turned around and hit the retract button when I meant to hit extend. If you hold what you believe is the retract button which is causing the pump to run and then go observe that jack you were operating, has it been extending or retracting? You could have a short or a failed control panel too however double check yourself just in case you got turned around as I sometimes do.

Sounds correct to me. Up button is to bring the coach up, not the jacks, and of course down button let's coach down, jacks up.

Man reading this post made me go inside, shoot a picture of my control panel and explain how mine works. I don't know if yours is same, but here it goes.

All 4 of my position buttons are either to:
• raise the two front jacks
• raise the two back jacks
• raise the two right side jacks
• raise the two left side jacks

So in your description if I understand it correctly, when you hit any of these 4 buttons, none of them comes down. Is that right? Because if that's what's you're saying—on my unit—they're not supposed to come down UNLESS.....

In order for me to operate these jacks by using these 4 buttons, is when I level Manually. Which is all the time.

In order to level manually, I have to:
• Have the engine running
• Emergency brake on
• HOLD the MAN button for 7 seconds then it goes into manual mode. THEN those 4 independent buttons are available.

The only way I can retract any of them is to hit the RETRACT ALL JACKS button.

Hope this helps this thread.

That is a control pad for Power Gear style levelers. The OP has an HWH system. Totally different than Power Gear.

My HWH systems work like everyone else's who posted in this thread. The motor runs when the jacks are extending. The motor does not run when the jacks are retracting. Up Arrow for extend. Down Arrow for retract.

[Mr_D]

On the HWH system the arrows show which way the MH will go when the buttons are pushed, not what the jacks do. Pushing an up arrow runs the pump and the jacks extend. Pushing a down arrow opens the bypass and allows the MH to come down as the rams retract.

Duh.......I mentioned that.

Thought it might provoke other ideas or for other folks that have the same system as I do and are reading this thread.
