FLYING BUTCH · 05-21-2017, 11:04 AM

07 Beaver Marquis. I am having to reset both reset buttons inside aqua hot (inside aqua hot compartment) in order for it to ignite and run on diesel???? When unit is set to diesel does the light, on the diesel aqua hot button inside the coach, stay on and the diesel starts when needed? I cant tell if the diesel will restart after I reset it? When I reset both buttons it starts and runs for as long as needed. It will then stop running and inside light on button goes off. After some time setting and I push aqua hot diesel it will not start. Just not sure if light should stay on. Electric aqua hot works fine and light stays on with it.
Thanks in advance for any help guys.

Safe travels all

I turn mine on and the light comes on. It stays on and the unit turns on and off as needed to keep temp up. The light does not turn off until I turn the HH switch off. I would look at the control board and see if there are any lights lit. Hopefully they will tell you whats going on. Google Aqua Hot and go to the companies website for all the manuals.

I am assuming your switches are multiplex? If so, it may just need to be reset. I believe you can do it by removing power to the coach for a few minutes. My diesel and electric switches stay lit after I press them, they do not cycle with the burner off and on.

Contact Roger Berke @ RV Hydronic Heater Repair.

My Diesel light would go out after 20 seconds of trying. Like the refer on LPG. Only it doesn't flash when it fails to light.

Do the PM. Change out the fuel filter, replace the nozzle, clean out the chamber. Solves 90% of the problems. $37 plus shipping was all it was for me.

I have not read this very closely, but it is worth noting that ground issues can look like Intellitech multiplex issues. I had some strange problems - lights on but no heat - and it all ended when I added a ground jumper to the main AH board. Just ran a heavy gage wire from the main negative (ground) to a new ground point.
