I've been driving cross country this week and shaking out the Newell on the way. Yesterday, I walked into the coach and heard a hiss coming from the base of the Knoedler air chair. Sure enough, it sounded like a giant leak coming out of one of the valves there.
I also observed compressor cycling increased to once every 2 minutes, up from 4 or 8 minutes previously (it has varied for some reason that I don't understand).
Rather than taking the chair apart while underway, I instead snipped open the supply line and inserted a valve. Now I can turn on the air to the chair, raise the height or whatever, and then close it off. When I get home I will work on disassembling and replacing the faulty valve(s).
Anyway, I was pretty happy: compressor cycle time increased to 12 minutes, so something like 80% of the leak was just the chair!
Later today, while underway, my coach started making a burning smell. Long story short, after pulling over and a bunch of debugging and help from Newell, it turns out one of the height control valves had just sheared off its control arm linkage thing. I aired up the coach manually, limped to a service center, and we fashioned a new linkage out of miscellaneous parts and pieces. We are back in business.
Very late this evening, I pulled into an RV park and set up shop. Immediately, however, I now notice that the compressor is back to cycling every two minutes -- with the leaky chair valve shut off.
I don't know if the latter incident has anything to do with the change in leak rate, but I am starting to suspect that I am cursed. I suppose this story is To Be Continued.
