All, I have a 2011 Winnebago Sightseer with 2 roof top Coleman Mach a/c units. Although the front unit works fine recently the rear unit has stopped working. I have checked the breakers and that...
Have there been any changes in how the coach is connected to shore power? Does this coach have any kind of load manager/shedder? Or 12VDC issues that would cut the power off to the thermostat? Winnebago has lots of wiring diagrams on their website. Good place to start.
