Replacing Coleman Mach 15 with Dometic Brisk II

Hi Everyone,

My Coleman Mach 15 which was installed on Labor Day weekend 2019 of course stopped working Labor Day weekend 2021. A tech installed that one, not myself. It iced over and then wouldn't even do that, no cooling at all. Nothing was dirty so I could only conclude it lost the refrigerant. I've read about the valve mods, but I did not not want to get into that either.

Not wanting to get the same product that just failed on me, I went with Dometic Brisk II. I didn't do my homework on the difference thermostat and wiring as such, but went ahead and bought theirs.

I found this old post and what I conclude is that the 12V power goes to the thermostat for the Coleman set-up, so this guy worked around it by running a short line from a light. I suppose I can do that I also have light close by, and there are ways I could cover that up in my very used RV.

The other thing is it looks like furnace connections are on the control box, not the thermostat. So I guess I'm stuck with not connecting that for now since there are only four wires to work with from the thermostat area to the roof if I need three to go to the thermostat itself.

Just posting for any other advice or experience with this.

If it matters, I have a '97 Winnebago Adventurer 37RW.

Thank you.

Well, update, after repurposing the wires on the roof, I only needed to connect two of them. I spliced in 12+ and 12-/ground from nearby light and then connected 12+ to TSTAT and control.

I have two wires I could still use for furnace potentially (needed three for fan high/low), but I'm in TX so I hardly ever used that anyway.
