1997 Fleetwood American Tradition/Spartan Chassis. Once my coach begins to air up i have a constant flow of air out of the Air control valve located under the front "hood". Its a Norgren K41Da00K1LK1L. If i place my thumb over the vent hose the front of my coach drops. Any idea why its constantly venting? Is it something that needs servicing?

Thanks for any advice.

That's the air dump/fill solenoid for your auto level..

You can try cycling it through an auto level/store sequence but most likely have to replace.

Mine did the same and I replaced.

Might try putting a little oil in the inlet side of the valve and then cycling it after about 5 minutes. Probably will have to do this several times. Sometimes air valves just need a little lubrication.

Must use air-tool oil to prevent negative reaction with O-rings and seals.

ive cycled it a few times. No luck. Where did you locate a replacement?

I will give this a try. Is it labeled inlet or is there a diagram somewhere to how these things operate?

As stated, try the oil 1st. I thought I edited my post to include that...but fat fingered I guess.

I got mine from Freightliner as it was direct replacement and it wasn't cheap. $500ish.

RV chassis parts has Parker valves for 1/2 price but wasn't sure if I would need to modify wiring. I was on a time crunch.

I finally got around to taking it apart and cleaning the inside and reassembled. No change. I ohm'ed both solenoids and they are 23+. I did notice one of them is really hot. also when i removed the wires and reattached i got a little puff of air when it re-energized....is either of those conditions normal? I dont want to just throw parts at it if those conditions are normal.
Also, when i push the button to extend the leveling jacks, she airs down and also releases the brakes....im not sure if the two are connected or not.

IF the brakes are actually releasing, something is dangerously wrong.
The way the rear suspension is made on a Spartan MM chassis, the front wheels will move forward approx, 4" when the air springs are dumped. Only the rear wheel brakes are locked when the spring parking brake is engaged.
