This problem just started happening this morning, My oven is set on approx. 350 and it keeps going on and off very quickly, the pilot stays lit. And then when I turn more that one top burner on, they are very very low flame. It is a 3 burner Wedgewood Atwood RV stove. In my 1995 Holday Rambler fifth wheel. Could this be a thermostat? Would a thermostat also cause the burners to be so low burning also?
