Halfway through the trip I swapped out the tanks. Now the fridge won't start on l.p.. I can't hear the starter nor do I see the flame. Its a year old fridge (don't have model number handy). I pulled over and connected inverter to onboard battery not to lose food. I will test voltage To fridge when I get to the camp. Otherwise I have no ideas (I think I have voltage to fridge for controls as the auto l.p. light seems to function. ). Any ideas?
