at this age it doesn't hurt to just pull it out and install an update. A smaller unit more efficient with less start amp requirement would be cool to mount up front and run while driving off of an inverter. ready for that upgrade. Home depot sells these wire buttons. they work great.

one other point to understand is phone wire crosses color one end to the other. if you hold the two ends side by side facing you so you can see the colors they are opposite. dometic understands thei but when you have extensions, they compensate for male to male couplers that switch the colors back. then if the application understood there was an adapter being used they would omit the color switch. so you may need to map out or switch up the wires.

I got up on the roof and measured and my stock duo-therms are 10" from the roof up. But I really doubt that they made AC units shorter in 1994 than they do today. I'm guessing the height includes some skirting that goes into the installation hole.
They aren't the shortest ones available, I'll get a measurement though. They are quieter and a little bit more efficient than most. They have separate fans for the evap and condenser, too. They are a really nicely designed unit and I'm happy with them.

Well....
Again I had it wrong.
Learning things...

Anyhow after testing and comparing the front Air to the center Air they are almost identical in readings. Then it occured to me to look at the 110V power feed. Well #$% there is no power. So now I'm in the back closet looking at the relays but I haven't found a diagram of the rear load center for a 94 WB. Does anyone know the link for one or know which relays under the floor go to what? Figure I would ask while I'm out there trying to figure it out.

Large galvanized metal box - 3 relays inside it (one for each Air Conditioner).

Dash switches pick them up by supplying a ground for the 12 volt coil.

Tested the panel circuit breaker (good) and the air conditioning relays (good - they all read the same). Went back and now I have 120 at the AC. I probably turned off the dash switch last time and didn't think about it. So back to the roof.

You also have to use two of the wires in the original cable(there’s 10 wires in the original cable) for 12v positive and negative connections from the thermostat to the control box. You also need to change out the control box to one compatible with the 5 button thermostat.
This seemed much easier than taking the ceiling panels out to run new wires.
I could not use the old wires to pull new ones. They would not budge.
Mine has worked fine since.
I will try to find the part # for the new control box. I think it was $ 115 or so on Amazon.
Good luck
Dan
The Dometic part # for the 5 button thermostat compatible control box is 3109226.005.

I decided that my sanity was worth more than the troubleshooting.
I replaced the unit.

So If anyone wants a DuoTherm for parts let me know. Who knows it might work just fine and I missed something. I have the AC on a pallet with the interior trim parts and thermostat. Free to a good home. I can bring it to WOG in Oct as well if someone wants it.
