Hello all. Brand newbie here. Yayyy! right? Lol, so I bought a 2020 Four Winds 24F in January and am basically living in it for awhile. Held up great in the cold with lots of propane.

I am replacing the standard Coleman Mach t-stat with a digital Coleman Mach 83303862. Wire colors and wiring are the same, said so on YouTube!

Shut off all power while changing out everything. Everything was going fine until the yellow (compressor) wire from the t-stat came out of the wirenut it was in. Before I could tell which wire it was terminated to.

Fished up the RV wiring bundle and found 3 colors, a blue (stripped), red (stripped), and a white (not stripped).

Terminated the yellow with the blue, turned it all on, had furnace but no A/C.

Repeated process with red wire, same results.

Didn't try the white as now I'm worried I blew something out in the t-stat or A/C.

If any of you have had any experience with this or need more info please let me know! I really appreciate It.

Thank you in advance! Have a great day!
