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...
If you have a 30 amp unit, Winnebago often has a switch that must be turned to "Generator" when on the gen. Mine is to the left of the switch panel and breakers. Maybe the switch is still in the shore power position.
It switches the rear AC to the 20 amp output on the generator.
