Hello Everyone!

My first post here and I'm hoping someone has an idea what could be causing this condition.

I have a 2021 Montana 3855BR Legacy with the in-command system. It appears that this years model uses Coleman Mach air units. The problem I'm having is that the front A/C unit will not turn on at all. If you select fan, auto, manual it thinks about coming on for a brief moment, then right back to off. One interesting thing to note is that the zone temp is displaying 0 degrees. The
other unit displays 74 degrees and is working.

I'd be interested to hear what everyone thinks.
