HWH leveling jack alarm

Good Afternoon from Honeyman's State Park on the Central Oregon Coast.

I have my passenger side rear leveling jack that goes into alarm when I am driving down a road(specifically bumpy roads...) This same jack is also the last to go down and last to come up with storing it. I just hit the store button and it quickly goes off.

Questions:

1. Could it be worn springs? When going down a rough road, it jars the leveling jack and it comes down a little triggering the road...along with it being the last to go up when storing?

2. When I am driving and have the leveling system up, do I drive with it in "store" mode or "off"??

Thanks,

Doug

    They CANNOT vibrate down. It takes pressure to extend a HWH jack. It is Road/exhaust Heat that causes the fluid to slightly expand in the lines and that can cause a jack to slightly extend. That is why HWH has the Store/Hibernation on the 300 series jack systems. Doug

    IF your touch pad does NOT say Computerized leveling, The manual states that every time you start the engine you MUST push the STORE button. That puts the system in hibernation. IF at anytime road heat causes the fluid in the lines to expand and push a jack down, the system sees this and will open the appropriate jack solenoid to retract this jack. It will happen so quick the buzzer and down light will not come on. IF the jacks are fully retracted, then hitting bumps and such will NOT cause a jack to extend at all, even if the springs are weak.

    Ours was doing that same thing. It was weak springs needed replaced. We put on new ones and no more problem. The new springs are shaped different at the ends but are the same length and fit fine.

    It could very well be the spring. I think once underway the jacks are supposed to be "OFF". Maybe someone with the same jacks can answer that.
    I have the old style manual jacks and there is a bridge on I-37 going into Corpus Christi and the concrete expansion joints are spaced just right that going across the bridge my jacks down light just blinks like a turn signal.
