HWH Air Leveling Issue

I have a 2003 Monaco Windsor 40PST with the hwh air only leveling system. When the system goes into leveling mode and the system raises the front past a certain point it starts releasing air out of the ride height valve exhaust tube. The air bags don't deflate but will continue to release air until either the tank runs out of air or I manually lower the front below this point. What could be causing this issue? Could it be the travel solenoids as I am also have issues with the front returning to ride height? Thanks for your help.

I have the same leveling system but I've never heard of your problem.

I would start by checking the air/ride height adjustment on the front bags valve.

The ride height exhaust tube is dumping air until tank is empty, but the elevation of the front end does not lower at all? In other words while air is being discharged the level isn't changing up or down, correct?

My guess your travel valve is not disabling like it should when you go to manual or auto level mode. Check the coil resistance of that valve. Check out the service manual for your model. You might have a series 2000 system. Here is the service manual for that.

What brand air system do you have? I have air only and its firestone. Got a program from whoever owns Monaco now and reprogramed the system and it works great!

It sounds like the Travel Solenoid Valve is leaking. When you go into the leveling mode this valve closes and shuts the air supply to the ride height valve, so if you have pressure there the valve must be bad. It's not a solenoid problem because the power is removed from the valve to put it in the closed position.
