To replace your Coleman Mach 15 48254C869 AC unit I recommend the Advent Air Replacement RV Air Conditioner for Coleman Setup # ACCOL150B which comes with an adapter harness that makes this a plug-and-play installation instead of having to splice everything together.
This Advent AC unit has a 1-Year warranty.

Hi Jon, I have a Coleman Mach 15 48254C869 that has stopped working. I replaced the capacitor but it still is not working. The compressor kicks on but then the PTCR switch on tip of the compressor sparks and the compressor shuts off. Then is try to come back on for a couple of seconds and does the same thing. I tested the PTCR switch and my meter saids it is good. The pipe starts to get cold when this happens. If I need a new ac does the Advent Air RV AC come with the Coleman setup? Mine is ducted and will I need a vent assembly on the ceiling? Thanks for your time, Bill
