So I have a nice new 240V 50AMP receptacle installed and my coach is runn9ing happily off it.

On to Air Conditioning.

My rear Basement Air is running fine, good Amp draw for each compressor and the RVComfort..PHP, Coleman-Mach 6535A336 thermostat works great.

The front one...not so much.

It has the old PSG Comfortstat thermostat and doesn;t seem to work. (Heating does though) I was told that i have a single compressor front AC unit and the build prints agree. Almost couldn't find it! It's in the center of the chassi accessible from two bays BEHIND 2 false carpeted walls on either side!

First. is there an easy way to determine if it is a dual or single compressor unit. And if it is a single, would the RVComfort..PHP, Coleman-Mach 6535A336 work as well for both heat and AC?? Wiring?

Attached is a photo of the wiring of the t-stat in front. I'm also not sure the RVcomfort one would even FIT in the little opening with door.


Any information would be helpful. Looks like the wiring is wrong.

I am getting closer to being on the road again!!

Thanks!!
