Hydraulic leveling sustem alarms on and off while driving?

Had a Winnebago that would frequently do that. Jacks were HWH. Winnebago told me that when raising the jacks, let them raise and let them time out rather than turning them off. Followed this instructions and jacks never again went into alarm while driving down the road. You might try that.

I noticed mine was alarming last year on the way home from Pigeon Forge. When we got back home and before I could check the level I noticed a small spot of oil under the hyd reservoir. Inspecting it I found that Monaco had relied on four screws to hold the reservoir in position at the weakest point possible, near the weld at the neck. I drained the tank and took it to a certified welder near our home. He wire welded the neck where a small stress crack had formed due to the tremendous vibration the tank takes while travelling down our "smooth interstates". He and I designed a brace on the back of the tank which I drilled and bolted it to the frame. I then refilled with fresh oil and problem solved. So I expect your fluid is low which as it sloshes around while travelling trips the sensor. If you do not have any leaks around the jacks I would inspect the above area carefully.

Most Monacos have hydraulic levelers with the pump/tank under the steps. Add some ATF.

Bigfoot levelers have a limit switch attached to each cylinder that's pressed in when the jack is fully retracted. Others use a level switch in the fluid reservoir to determine when all jacks are retracted.

We experienced the same thing last month on our drive down to Florida.
We have Bigfoot levelers.

I called a contact phone number I had of a guy at Bigfoot and he said one of the levelers was probably down 1/16th of an inch causing the alarm to sound.
He instructed me to tighten the bolt on the bottom of each leveler pad.

I had gotten off the highway and really didn't want to go crawling under the rig in freezing temps so I thought I would simply lower each leveler a short distance and then retract them and see if that would solve the issue.
Luckily that is all it took. Never heard the alarm the rest of the trip.

Please tell us what system you have. The alarm is triggered by different things on different systems.

Mine sounds when the fluid is low. Yours may be right at that level.

Mine was fluid level being borderline low.
