I am wondering if anyone has any advice about my water heater problem... I just used a new-to-me Jayco 1206 popup camper, 1998 I think. It worked great but the water heater has an odd problem. It has an older style 6 gallon heater with a pilot light. I light the pilot light as I should. Within a minute on prime it stays on like it should. I turn the unit to 'on' and the main burner comes on like it should. It runs for 3 to 4 minutes, then there is a click in the control valve, and the whole unit goes out, both main burner and the pilot light. I can turn the controls back to 'pilot' and light the pilot again, and then go back to 'on' and it works, again, for only 3 or 4 minutes. One time the pilot stayed on, and the burner came off, I ran the hot water till the burner came back on, but then when the burner went off, it took the pilot with it... I am guessing that instead of turning off the burner, all the gas is going off, or there is too much draft, and the pilot flame is being sucked into the tube with the main burner, and the temperature sensor is cooling down, or something else. Does anyone have any suggestions?
