vrich Report post Posted October 10, 2016 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? Share this post Link to post Share on other sites
dickandlois Report post Posted October 11, 2016 vrich, Sounds like you might be having issue with RFI. Radio frequency Interference. Do you get all 0000's on the display? There are so many items now that do not work well with this kind of interference around. Starting with florescent lighting. Do you have any of this type lighting? Then do you have any remote controlled items that use RF Frequencies to control anything(car fab) ? Do you have wireless internet that you use ? the most common sources. Cummings auto get start system? Then you get into Cell towers or other government transmitter sights close to you location. The fact that the shop can keep saying it works at there location, could pin it down to where you park the coach. Have you seen the system work when you pick it up ? Might try to go to a sight where you are away from any of these sources - run the reset and see if it works. No change then its got to be a local source. that gets into shielding and making good ground connections and cable connections. This problem can be like chasing a ghost. Rich.
