leveling gear alarm while driving

So, I'm driving home and for no apparent reason the "JACKS DOWN " lights up on the Power Gear control panel and a very annoying " BEEP, BEEP" is happening. Trust me, this will have you hunting for an exit PDQ. Find an exit, jump out, get a visual on the jacks, All seems well. Extend and retract, no change. Drive some more and check again, no change.
Temp in the 90s - pavement seems like 130, I'm thinking it must be a limit switch on one of the jacks. Which is more bearable, crawling around on HOT pavement and gravel on the roadside OR "beep, beep, beep" for the next 60 miles? I chose "beep, beep"

later on that same day --

I started this post to ask about this situation, but knowing that I'd be hammered for not giving enough detail, I stopped and went for the manuals (if I had the one for the jack system). Sure enough, found the manual and hopefully, the problem might be low fluid in the reservoir. Wouldn't that be peachy? Next question would be "where did the fluid go?" Cylinders are dry, as is the pump. I'm not above just adding fluid and hoping for the best but kinda wondering, guess I'll be checking the hoses. Along with the manual I found a tip sheet dated Dec. 2011. It details how to test and replace the fluid sensor/float switch. Guess the prev. owner had maybe this same issue.

Now I don't have a question but killing time until things cool down enough to check things out. Guess I'd rather have low fluid versus a defective switch.

  • I had this problem twice over the years.

    1. 'They' filled the reservoir down south when it was hot. When we got up north and it got cold, the fluid contracted, the level in the reservoir went down and the switch activated off and on as we bounced down the road. I checked the level and added fluid. There was no leak.

    2. The float switch failed. There was no leak.

    On my RV the hydraulic reservoir is readily accessible as is the dipstick and the float switch.

    As a by the way- when we bought the RV the mechanic pointed out that there are manual valve actuators on the pump/reservoir assembly should an electric solenoid fail.
  • Ours recently had that alarm going off.
    I pulled the fuse to silence the alarm, and added fluid at my next opportunity.

    Dunno know where the fluid went. No oil on the jack cylinders, no oil under the coach. not gonna worry bout it till it happens again.
  • Fill it up, exercise the jacks while observing the hydrolics
    It will be obvious where the leak is!
    Pull the bad hose, take it to a hydrolic hose shop and get one made, install, fill, get the air out, on your way!

    Don't ask me how how I know.....
  • One of the funniest memories of my early days in a MH was going across Wisconsin with Kleenex in our ears because the jacks were low on fluid and I did not know how to shut the alarm off and could not ask the dealer as it was a weekend
