Hello. As the title states, my dometic fridge will only run on gas if I unplug the power cord. It runs on electric just fine and gas just fine. It's just that if I switch it from auto to gas, the gas never fires unless I unplug the power cord. Am I correct to assume that the eyebrow board is not cutting power to the heater when I change it to gas mode, so it doesnt know to fire the gas?
