So we got the AC motor replaced and running. New ends on data cables and furnace now shows on thermostat. Testing exchanger and fan this weekend. Thanks for all the help.

On my 3rd time (2 weeks ago) asking I got 10 different pdf's from REV, they said it is all they have but going to wait another couple months and try for paint codes and plumbing diagram. Only things I am missing.

Hey Vito, thank's for the reply, all information helps. All 3 units have heat pumps. Back 2 units thermostats show fan , cool, heat pump and furnace and all these work as designed. Front unit only shows fan, cool and heat pump no furnace. It is the one with the furnace dip switch turned off. I have cleaned the rj11 jacks and replaced 1 inside control box. Will drop decorative panel and see if there are any connectors with pig tails that need cleaning there. (Not an easy task, 4 7/16 bolts 1 each end and 2 in driver side. Takes 2.of us to do it safely. Do we just blame Monaco for none of this being in the prints or manual. Especially the part about heater craft fan speed control and front furnace exchangers? Chris

Hello, I need help with front AC, furnace and heater craft heat exchangers in the front of our 2006 Navigator. We may have to change out the original front AC and are currently waiting on a new fan motor, and if that does not get AC portion working according to tech, then it will need replaced. So I need to know all about this so we can get it back to original working order (suspect it is not correct now). What we have 2 Dometic CCC 5 button thermostats (both 2006) 3 Dometic Duo Therm rooftop AC’s ducted (all 3 2006) Aqua-Hot 100-04S and heat exchangers in bedroom, under shower sink, under toilet sink (with multiplex fan switch), under kitchen cabinet with ducting to toe kick register and behind couch, this unit has a Heater Craft off, low, medium, and high fan control on lower cabinet. In the bedroom on the dual zone thermostat, zone 1 is bedroom exchanger, zone 2 controls the shower area exchanger. The toilet room has an exchanger fan switch for that exchanger. All of this works for cooling, heat pumps and furnace. Currently the front AC has as far as I can tell the original control board. The board has dip switches but the furnace dip switch is not on. The control board does have 2 data cables plugged in. I have tried setting dip to furnace and do a reset on thermostat but furnace never shows up on screen. I have read on Irv2 that the coach's heat switch on the kitchen cabinet powers the exchanger for the cabinet toe kick vent, the under couch vent and the cockpit center vent if equipped. I have been unable to confirm this functionality as the switch does not do anything and I have so far been unable to test. This thread talks about the order of use as 1. Turn on AquaHot (let it heat) 2. Turn on wall thermostat for heat, furnace never shows up. 3. Turn on Heater Craft Heat Exchangers, not working as furnace not on. https://www.irv2.com/forums/f115/holiday-rambler-heater-craft-626178.html This thread talks about the function but my schematics/prints book does not show show anything for this whole setup (could be a page missing) but the 2006 Navigator prints in the files section does not show it either. So I am hitting a wall and need some direction from the Monacoers knowledgebase. Chris & Donna

We worked on this a good bit today. Here are the results. If I maunally raise the coach all the way, the air does not dump out after 45mins. If I do an auto level the air dumps as described above. Did find out I may have an air line swapped with another. If I press the rear lower button, the front right lowers. Hum the wonders of used coaches. Still looking for advice. Chris

When air dumps the panel shows air light red, front and right levels yellow, all 4 warning lights red. This seemed to work but right side was low. Will do more investigation on this. Makes no difference

I have been away from coach for a few days and old memory what it is I cannot answer all accurately. I will dig into answers Saturday when back. Thanks for all the suggestions and advice. Chris

2006 HR Navigator 43PBQ, DD60 515hp. So I can start engine have air to 120 front and rear tanks. Press the HWH air button twice to level coach. When level air light goes to fast blink. I then turn off engine. After 25 minutes the rear dumps air from bags then right after the front dumps air. I find no leaks or other indicators. I also have had no luck searching the internet, here and irv2. Anybody have any ideas for next steps? Chris

Merry Christmas to all.

Thank you

What is that little button under keypad?
