I have a 2017 Winnebago Journey with Aquahot. The coach thermostat seems to be in need of adjustment. Does anyone know if a Coleman RV Comfort.ZC is adjustable? Or does it just need replacing? It does...
I had similar problems with my 2015 Tuscany. I figured out the problem by hitting each thermostat sensor with a hair dryer. My problem turned out that one sensor was not even connected. Easily figured out by watching the temp go up or not. Dealer hadn't a clue even when shown the data.
