Hello! We have a situation. Our Dometic refrigerator works great. That is on propane until we hook into shore power. Then the check light comes on. Resetting it and checked the breaker box. All ok. Turned the fridge off, pulled the outside panel off and the pilot flame was still running. Had to shut the main tanks all the way off and burn through the residual propane in the lines to get the pilot off. Meanwhile the rv is still on shore power. So now everything is off. I start the fridge on again. No problem. Turn on the tanks. No problem. Why are we having to do this every time we plug in? The fridge is set to automatic. Never had trouble before. The coach is just going on 3 years old! Any thoughts? Do we need a replacement of some sort? Thank you!
