Hi, Happy to be part of this portal, already got answers to many of the questions and doubts, except this one. Let me explain our 2007 fleetwood arcadia, so that you can related it to yours. My model has panel at the bottom of living(sofa) area, where I can see these things: Water heater switch and indicator(red light) - turns on when I turn on the switch. Brown colored thermostat Circuit breaker panel ------ Thermostat has: On Top : A lever(or switch), very hard, it moves very less, I could hear "click" sound when I push left/right though. On Top: I was expecting another lever to up/down the temperature, I could see temp. indicator, but no lever. Is it missing? On bottom: I have another lever showing fan speed, which i can push left/right. I ensured the propane is on, turn the thermostat's top switch, waited for long time, nothing happens.
