I have a 95 HR Endeavor with dual AC roof units. Each is controlled by a separate thermostat. The Rear AC stopped working, and it has been determined that the Thermostat is bad. One would think this is a simple problem - buy a replacement stat and install it - WRONG. The thermostat is a DuoTHerm, Model #3105356.004. A web search failed to find one. I stopped at several RV dealers, no luck. Last RV dealer called Diometic and learned that my thermostat had been replaced by Model #3108701.339. Problem solved you say - WRONG again. That unit has now been replaced by Model #3307713.010, which not only requires the purchase of the thermostat, but a control unit for the AC itself and some wiring, etc etc, all at a cost of almost $350. I would like to wire in another stat, have seen several articles on replacement of the analogs with the Hunter digital battery operated units, BUT, my unit doesn’t have separate colored wires, but a flat ribbon with a plug. Has anyone else had this issue - any suggestions on how to fix such a simple issue as a thermostat replacement at a reasonable cost?
Thanks
