Hi Gjac. Sorry I am fairly new to this site and had a hard time finding my post. You wanted to know what system I have. It is a power gear / Milwaukee cylinder 3 Jack system. Doug

Our old HWH jacks would do that from time to time, the store button always solved it - and the fluid level was good.

This type problem as related to HWH is NOT slight lack of fluid or an Air Bubble. HWH systems are self bleeding and the Down switch is magnetic. IF the Down light comes ON and you have the 300/325 series HWH touch pad system the fix is to just hit the Store button even while driving and the offending jack will retract. That jack has extended due to in transit Road/Exhaust area heat. The fluid in the lines expands slightly from this heat and will cause the jack/s to slightly extend a little and this opens the Down switch on the top of the jack. Hitting Store allows that expanded fluid to be pushed back into the reservoir. The Owners manual for this system from HWH states to ALWAYS push STORE after the Chassis engine is started. This puts the system in sleep mode and IF the Transit Heat problem causes a jack to extend, the system will activate the Store mode automatically and the offending jack will then retract and there will be no dash area indication of this.
The OP's problem is low fluid in the reservoir or a defective float switch. His year/model has Powergear HYD jacks. Most common is low fluid level OR the jacks are NOT fully retracted but look like they are. IF his jacks have the Grease Zirc on the bottom collar on each jack he needs to insert grease with a grease gun. This helps the PG jacks retract easier and fully. Doug

Not always fluid related.

I got that terrible "Jacks Down" warning one time while driving on the highway in pouring rain. I stopped and checked the position of the jacks and they were all properly retracted. I disabled the alarm and returned home.

My investigation found the Trombetta switch for reversing polarity had a cracked housing. Water entered the housing and shorted out the solenoids tricking the system into thinking the jacks were deployed.

I ordered a new switch for under $60.00, installed it myself and things once more work as designed.

Moral of the story, check the fluid first but if that doesn't solve the problem you may have to dig deeper.

Not always... My Bigfoot hydraulic jacks have individual limit switches that open as each jack retracts. I've had intermittent jack down alarms when the rubber plunger tip on a switch deteriorated.

Your pace arrow has a power gear hydraulic system.

The fluid reservoir has a float switch, when all the fluid has returned to the reservoir (all jacks are all the way up) the float floats and the jacks down light goes off.

The level needs to be all the way up, as in running out the fill port.
On our 2000 PA, the pump and reservoir were behind the batteries, pass side compartment in front of the door. Stone beetch to get at.

If it's hydraulic it is always fluid level. In my case the sensor on the reservoir was bad. Fixed It myself but the part was $150. Until I got it figured out I would visually check the jacks then disconnect the buzzer alarm.

Not all systems are hydraulic, mine are electric,Mine don't have fluid.

[Gjac]

What system do you have in the MH?

[Ava]

The fluid level in the reservoir is probably low or else the float switch that turns off the alarms when hydraulic fluid returns is not working. Check level fluid first. That was my problem before.

X3 Add a little ATF to the jack pump/tank.

Or something is blocking one or more of them from completely retracting. If they aren't in the "stored" position, the system thinks they're down. Either way, its time to get on your belly.
