Thermostat malfunction?

My RVComfort.zc (p/n: AM 7812) thermostat is suddenly reading 20-40 degrees warmer in zone 1 (front) than the actual temperature. Zone 2 (rear) is working fine. The coach does not have any florescent lights/ballasts; not aware of any IRF sources; and the fuse(s) have been pulled a couple of times to let the system reset, without success. The front sensor is unchanged in any way from when the system was working appropriately. Any help/suggestions will be greatly appreciated.
Thanks for your assistance.

Check the wire (spade) connections at the upper control board (+ & -) and at the thermistor, they sometimes go high resistance.
