Have a 2002 Fleetwood Revolution. bought a new RV ComfortZC.. Took it to a dealership 2x and they reprogrammed it 2x and said it was working. NOT!!! After reading blogs it seems I'm not the only one with this problem. Took the fuse out of box, unplugged thermostat put back together. Stayed on for a few. Lite up, but no zone control, no temp control or no ac or heat switching.
ANY IDEAS?
