Pictured in the first post, what you're looking at is behind the fridge. Go out behind the camper, take the vent cover off behind the fridge area, you'll find a vent flue. It's all the way to the right on mine. Halfway up that flue you'll see two wires and a round connector. In the center of the connector is a button to reset the switch (switch/breaker/thermo-fuse...same same).
Check for evidence of fire or overheating melty wires and things, press the button back in and test.
Read my comments also about open flame dangers and cleaning the gas jet if it's a similar condition.....also your switch may look different, as the manufacturer changes things all the time.
