4 or 5 button Comfort Control? Do both A/Cs work off the same t-stat?

What happens on the thermostat when you try to use this unit? Zone 1 or Zone 2?

Does the fan come on? Any noise at all from the unit?

Zone 1 basically nothing. On Fan only or AC setting - the front unit clicks once and nothing happens. Fan does not turn on.Zone 2 operates fine. The rear unit turns on at the appropriate level set.
RV Mechanic: Randall, RVIA Certification replied 6 years ago

That is probably a bad ceiling control box. Take the ceiling grill down like you are going to change out the filter and get me a part number off the box.

The Electrical kit number?If so, it is Part#3109226.005
RV Mechanic: Randall, RVIA Certification replied 6 years ago

That part is still available and should run about $119 or so. Shop around as the price varies. Just plug it in.
