The AC not working because of a temperature sensor reading is not just limited to RV's. On my Chevy HHR, I occasionally get an out of range temperature reading on my scan gauge and a zero reading on my dash temperature gauge. As soon as that shows up, the AC will no longer work.
Fortunately or unfortunately with today's computer controlled systems, one sensor reading can affect several different systems.
You were lucky to find a shop with a mechanic that knew what he was doing instead of taking it to another shop that would have replaced the AC compressor and thrown a lot of other parts at the coach until they finally found the single issue that was causing the problem. Be sure to post your experience in the RV service review website(
RV Service) so that others can utilize this shop if they are in the area.
