2002 Monaco coach won’t dump air. HWH 600 series.

[Reisender]

Hello. New to this forum. Think this is the right place to put this.

We have a neighbour with a 2001 Monaco Executive. Apparently model year 2002. HWH air levellers. Older gent. He can not get the air to dump. Consequently the first step is high and causes problems for his wife who has mobility issues due to Parkinson’s.

When you push the dump button (key on) all the lights flicker. I checked the voltage on a terminal marked “air dump” in the cabinet below drivers position and it drops to 11 volts when butting pushed. I can hear a relay opening and closing when the button is pushed.

Any ideas?

Thanks in advance.

push the on button twice in rapid succession, see what happens.

Are the levelers REALLY air operated ?
Kind of hard to raise that much weight with air.
I would think hydraulic.

Has any one LOOKED to see if the jacks are really down ?
Sounds to me like the indication is that you are telling it to raise the jacks when they are ALREADY UP.

Then.....the leveling system should have a manual mode.
Raise the levelers, which probably is NOT the "dump air" function, and then start over in the manual mode. Might have to have the engine running to do this.

If mine is reasonably level to start with, I just run the jacks down until they make firm contact with the ground for stability and not for leveling really. If his unit doesn't tend to sway when people walk around inside, he might not need the levelers at all sometimes.
