Jacks down alarm

Anyone have the "Jacks down" alarm come on while driving (for no apparent reason).
Scared the crap out of me and when we pulled over and looked, non of them had moved.
I exercised the jack that had an indicator and then auto secured, and it went away. I have a2011 Itasca Senova 33C.

Unplug the sensor at the reservoir and don't worry about it. I never move until I visually verify the jacks are retracted.

Low fluid. Had the same happen to me. Gets your attention when the alarm goes off when you are driving down the road. I noticed that when I hit the breaks or turned to the right the alarm would go off. I unplugged the control board and continued on to the rv park. Picked up some DexIII, topped of the unit and never had a problem since.

A bad sensor will do it as well!

Same thing in our Winnie, only needs to be low a few ounces to turn the jacks down alarm into a rough road / incline warning device. On ours the reservoir is located behind the front drivers side tire, with an 8 screw access Panel in the cargo bay.

Not an uncommon problem. One cause is that the fluid will warm up a bit and expand just enough to push one cylinder down enough to set off the alarm. I just hit the on button then the store button while driving and the problems corrects itself. Scary the first time though.

Happened to me on our last trip, like you scared the heck out of me. The alarm stopped after a few seconds. Later got a dittle - diettle alarm for a few seconds, still haven't figured that one out.

We had this going across KS this summer 105F day. We have HWH jacks and the problem was the fluid expanding and driving the jack down just enough to trigger the alarm. But is does scare you when it goes off at 65mph!!!!

Jack problem resolve

I had that problem, panic set in, thru out the anchor. I learned that when retracting the jacks - just because the lights turn off wait another minute.
This should keep the peace! Enjoy your travels.
