Seems like when parked and the system has leveled the front end is rising a little every day. The last week or two front is lowered completely and the rear is up 3"+/-. HWH touch panel shows no yellow lights. Have re leveled using the interior door test.
Thoughts?
Out of level and no lites, maybe the computer has lost contact with the level switch or a board problem.
You can check the cable connection on the level switch and where that cable connects to the computer?

Scott, There is a pressure regulator under the front of the coach. Its purpose is to allow the rear to come up faster than the front since the rear is heavier. Check to see if it is leaking or working properly. 25 Dollar fix if its dead.

We actually use the kitchen counter and the bathroom door.
After level we seem to drift up in the front a little each time the Aux. Comp. comes on. Is not measureable at the time but over 2 to 4 weeks I can energize the HWH level control panel and push the front down button and it drops back to "good".
I had been thinking that we were loosing a little bit of air through the rear manifold but it appears that the front is rising. Interesting..... ;D
You might consider recording the air bag height measurements over time - that can help you figure out if it's related to a ride height valve or one or more of the HWH solenoids. We've done this on a couple of occasions where we were having leveling system issues and it really helped. I just measured the distance between the metal plates and tracked them in an Excel spreadsheet.
As usual Michelle you have a great suggestion..... ;D
Scott,
It looks like another case of more than one thing wrong.
There are only two ways for air to go onto an airbag, through a travel solenoid or through a raise solenoid.
A leaking travel solenoid will let air migrate from the air tank to a bag as long as the pressure in the tank is higher than pressure in the air bag. However, as the coach goes above travel height the ride height control valve goes into the let air out of the airbag position from let air tank air into the airbag position and the coach will stop rising. So, if your coach is rising above travel height, I don't thing it's a travel solenoid.
That leaves the raise solenoid, but that would only add air to the bags on one side, unless both raise solenoids are leaking and that's unlikely.
So measuring the airbags to determine which one is rising will point to the leaking solenoid.
You also say when this out of level (front high ) condition happens that you don't have any out of level lights on. The level switch should sense this condition and tell the computer to turn on the out of level lights, something else to chase!

My coach does the same thing only in reverse. After 2-3 weeks the drivers side is obviously low and the rear airbags are at max height
I may have read that wrong. My left front (driver side ) is low, all the rear airbags appear to be fully extended. Curbside front looks normal. I'm going the measure and get a better idea of what is actually happening.
I also guess that the sensor under the cabinets has something to do with situation.
Thanks guys and gal for your input. :D
