Dometic Fridge Gas Problem

I just had a problem with mine last month not wanting to stay lit when unplugged. Started with basics...clean/blow out burner and is working correctly again. I also loosened the ground screws and re-tightened them to make sure of good contact. Worse case happened two years ago, had to replace the controller board due to one of the tabs for the glass fuse being corroded and not turning on the fridge at all. Bought a Dinosaur(spelling?)control board and now I don't have to remove the fridge lite bulb when turned off and also provides a temp adjustment the original did not have.
