Auto leveling

[2008DYN]

I have 2008 Monaco Dynasty with Valid Air Leveling system. Never worked since we purchased it three years ago. Finally took it in to get fixed. Turns out auxiliary compressor not even there. New one installed. Coach held level for eight days before auxiliary compressor came on. Now it runs for approximately three minutes before turning off. Five minutes later it comes back on for another three minutes. Cycled like this five times before I started coach to air system up before neighbors complained. Is this normal?

This was leaving the system powered up, auto light flashing?

Neither sounds normal to me ... 8 days before first refilling tank, or refilling every 5 min.

Is this a Valid / Power Gear system?

No, that's not normal. With coach sitting for 8 days, did the coach start to drop or did it stay level? If it stayed level, your system is pretty tight with very little leaking.

However, I'm betting the reason the compressor keeps cycling is it's plumbed wrong. I've seen several coaches, including mine, that was plumbed wrong from the factory. There is an inline check valve they put in separating the tank from the pressure sensor. it needs to be moved. It should be mounted immediately after the compressor. It's not a difficult job if you're handy.

Yes to keeping it in the auto mode with the auto light continually flashing. Valid system

Thanks for your reply. The coach did stay level. Over the past week you could hear a periodic sound of the system putting air in to keep it level. Currently we are 1600 miles from home and the Kenworth dealer who installed the new equipment. I am going to look for some help where I’m at. Thanks for the information.

Only thing I can think of, is if it was always releasing small amounts of air from select bags to keep level the first 8 days, then changed and began adding air.

Regardless, shouldn't be refilling the tank every 5 min.

Let us know if you / they, find anything.

I would bet it's the check valve installed in the wrong place. Monaco put the check valve at the tank where it does not belong, like the other poster said, move it to right at the pump and make sure the pressure switch is teed off that output line and above the pump.

What happens if you leave it in Manual or in Travel mode?

We had a 2008 Monaco Dynasty, 42 ft., Diamond IV floor-plan, air leveling and hydraulic jacks. I had never heard our pump until it was about 7 yrs. old. It was located somewhere near the front axle area.

Another thing to consider is that your airbags are probably original and might need replacing/inspecting. All of the air fittings should be inspected to make sure that they are tight.

On the Prevost site, it is recommended to replace all fittings to 'compression fittings' for a better fit (you might have those already). Chasing leaks can age a person 10 yrs.! The ole 'spray bottle with water mixed with Dawn' can be your friend.

If you ever get under your coach, make sure it is blocked so that it doesn't come down crushing you if it suddenly loses air.

Good luck,
Mark

Thanks for your reply. I will post once I find out what the problem is.

I have had to turn the system off now to keep the auxiliary pump from acting up. Until I get this fixed I will just air it up manually periodically. Where I’m at is practically a level pad anyway. Thanks for responding.

I requested the Kenworth dealer my RV dealer takes coaches to for chassis work check all the fittings for leaks. They assured me they did. Before the latest work was done I was not willing to get up and under the coach for the exact reason you mentioned. I know exactly where the new pump is. I will check to see if the check valve was placed in the wrong location. I’m far away from home and all my tools. Probably will have to pay for on site repair. Just want to know what the problem is before looking for someone. Thanks for replying.

The FRB should have a self resetting CB or fuse to turn the pump off. I haven't used my pump for quite some time as it always seems to come on at 2 AM.

Does the coach stay level when manual is selected? Travel Mode? I'm just wondering what is working and what is not.

Just got off the phone with the Kenworth dealer who installed the system. The reason the compressor doesn’t turn off when I remove any one of my four auto leveling fuses is because the tech wired it by passing the drivers side fuse box. He installed a new dedicated wire with an in-line fuse directly behind the fuse box. I found it and will pull the fuse next time it goes on and won’t shut off.
The coach also doesn’t stay level in travel mode. According to Kenworth I need a ride height control module. They tried twice to get Rev Group to return their calls in order to track down this part but never got a call back.
As far as in the manual mode I’m not sure. When the compressor was going off and wouldn’t stop I put the system in the manual mode thinking it would stop. It didn’t. I now have the system off and just waiting to see what happens. Thanks for responding. Any other advice would be welcomed.
