Malfunctioning Coleman Thermostat
My 2005 motorhome has two Coleman Mach 2 A/C units controlled by a single Coleman RV Comfort ZC digital thermostat. Two to three times a year, while running the A/C’s, our t-stat will make a poppin...

Fleetwood back your year wrapped the 120 and tstat wire harness together in the roof. THAT causes the ripple trip for 00. The ONLY true fix is to run a NEW 8 wire tstat wire from the Zone 1 to the wall tstat. Bypassing the 120 wiring as best as possible. Due to the type control system RVP uses, there is no after market tstat control system that will work. The other solution is to replace the control boxes and run a separate tstat wire bundle for the other zones and install regular RVP wall tstats which will be expensive. Doug
PS, since you have 3 AC units, the problem "could" be the com wiring between the Zone 3 and Zone 2 and then going to Zone 1. Those wires could also be wrapped with the 120 wiring. Can you determine if the 00 is isolated to just one zone? Or when the trip happens the complete tstat locks out with the 00?
