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 is not the issue.
The blower does not run and the compressor is not running. Seems like either there is no power or the t=stat is faulty and not calling for the unit to run.
It is 85 degrees in the unit and the t-stat is set at 72.
