Turn off air leveling?

From my cell phone (hard to search).

How do I turn off the air leveling on 2003 U320? Coach is level, but today re-leveling about every 30 minutes, scaring the cats sitting outdoors with us.

Thanks for any info,

On the older models (like ours) I just push the "OFF" button on the HWH touch panel.  Does this not work on your coach?

Thanks for the replies.  I just pushed the emergency off (stop) on the HWH pad (after turning ignition switch on while doing it).

I'll see if that prevents air release for re-leveling.  Has done it a couple of time in past 2 hours. Scares the heck of the cats when they are outside with us on their leashes.  Air pressure holding steady, aux air compressor has not needed to run.

Dan,

The HWH algorithm with have the coach first exhaust air on the high side/end/corner as needed to maintain level.  It wakes up every 30 minutes or so to check level and adjust if needed.

It will only run the aux compressor AFTER it has lowered the high location as far as it can safely without twisting things.  Only then will the aux compressor run to raise the low spots (and then only if there isn't enough pressure in the tanks to do so).

If the coach needs to "re-level" this often, it would indicate a pretty significant air leak somewhere in the leveling system.  Next chance you get to do maintenance work on your coach, you might want to go leak hunting.  In the meantime, if you are parked on a level spot, you could drop the coach down onto the mechanical stops and turn the leveling system off.  That way, the coach will remain sitting level in spite of any system leaks.  Some members follow this procedure every time they park, because it gets the entry step closer to the ground - easier to step up and down!

First time in our travels it has re-leveled multiple times in one day.  Usually only happens once every couple of days, but it always freaks the cats out when it releases air.

I'm positive up to now no major air leaks. Haven't seen any mud daubers around, but if it continues I'll check the ports on six packs etc.  This coach holds air pressure extremely well - aux pump very rarely runs.

Any chance one side is getting hit by serious sun compared to the rest?  Heating of air bags (and resulting pressure increase) on one side (or corner)?

Yep, that is the case through the day.  Parked north/south, so sun on one side in morning, another in afternoon. And today was sunny.

Good observation.  I see it in tire pressures on the monitor all the time.  This coach is amazingly air tight and free from leaks.

Just keep and eye/ear on it.  If you do turn off the leveling, take measurements of the air bag heights at that point.  If it looks like things are becoming unlevel over time with the leveling off, retake the air bag measurements again (between plates, not from the ground up).  This will tell you if a corner is leaking down.  Could be as simple as an o-ring in the six-pack needing to be replaced.  They do need that every few years or so as the seal dries out.

Mud daubers would only affect the exhaust ports - preventing a corner from lowering.  This is really obvious if you try to dump all the air out of the leveling system (or if you can't level from ride height because one corner won't lower).
