TO MY RV FRIENDS: As a long time RV'er, I always share info that could help my fellow Rv'ers... My 02 3560 had the thermostat in the hutch cabinet side wall. "NOT CONVENIENT!" I had to open the large slide to get to it. I now have it where it should have been placed from the factory, on the hallway wall. Well in the process I blew a fuse and had no 12vdc at the thermostat. I checked the 12vdc A/C fuse in the fuse panel, and the 110vac breaker. Both good. Oh crap what now! Well here is the secret. Up inside the front Roof A/C unit is a control box full of wiring and a circuit board. It has a little 3a fuse inside! Even though not my problem, there is also a telco style RJ11 plug on the end of the thermostat wire inside that control box. I read where it can get corroded and cause the same issues (FYI). And while you are on the roof with the cover off the A/C unit, clean the coils and lube the motor shaft on both ends. The lube will work it's way into the bronze bearings. FYI, I bet I blew out a pound of dirt from each A/C units coil assembly. I will also bet that has never been done! They blow like two hurricanes now! Due to what I have now learned about RV roof air units, I am glad I blew the fuse! It is just good you did not see this chubby guy with two bionic knees going up and down that 11.5" RV roof a zillion times!!! Between the repair and servicing both units I bet I saved $500...
