Well...
It worked all morning and after 3 hours the "new" t-stat is doing the same thing on AC #1. So I'm back to troubleshooting. Since it was cooling like a freezer at first, I'm thinking maybe one of the compressor wires is grounding out? Well we are back on the road to home on Monday.

I'll pull it apart when I get back and spend several quality hours looking through the rest of the system.

As a side note the humming from the connectors stopped. I guess they knew that I was going to check them out too.

The thermostat is goofy. Swapped with my rear thermostat and it runs like a champ. So now I'm in the market for a Dometic Duo-Therm Thermostat for an electronic control. I pulled the circuit board to check for any loose connections but it looks solid
I think I have what you need lying out in my shop someplace.

Thanks guys. I'm driving back to Alabama from Arizona starting Monday, so I'll get back on track with fixing this in about a week.

Finally got up on the roof to check it out. Sadly it looks like the compressor has a short.

Common > Start : 7.1 Ohms
Common > Run : 0.7 Ohms
Run > Start : 7.5 Ohms

I'm guessing that there is a converter to allow reuse of the thermostat ribbon cable with a new AC unit?

I'm thinking that I'm going to go to the Dometic/Atwood Air Command as they are suppose to be the quietest on the market and it would be nice to be able to run the AC and hear the TV at the same time without pumping up the volume to 30.

Does anyone have any experience with swapping these out that could share any gotcha items to make sure to watch for or have on hand for the replacement?

Hi Bruce
I replaced the analog thermostat in my 96 WB on the middle AC last month with a 5 button digital. I cut the ribbon wire off and used the cable that the ribbon attached to. I cut the ends off a 4 wire phone cable and spliced the ends to the original cable using phone wire crimp connectors. 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

Hey Andy, How tall are the Atwood AC units?

Online it says 13.6" tall, but then it says a low profile penguin is 12".
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.

Those resistances look fairly typical to me?

You didn't mention checking the resistance from the windings to the compressor case - that's a very important test.

The resistance between any winding and the case should be near infinity - if shorted to the case, the compressor is bad. Otherwise, I wouldn't condemn the compressor yet.

I second that on the winding resistances. You really want to look for open between conductors and low resistance from any wire to the case. (both these are bad). .7 ohms is reasonable for the armature. You already have good references; take the time to pull the cover off one of the good ones and check those resistances and compare. You may spend an hour and save yourself $500-$1000; I know I don't get paid quite that much :-).

Will do. After I posted I was thinking on this and felt that I missed something but couldn't think what it was. I'll pull the cover and check the windings to case and the leads. Thanks!
