Water heater will not stay on

[bwalden]

I have a new (2017) Jayco TT and an old (2003) Dutchman TT. Problem with the gas water heater on the Dutchman. Heater will light and burn for about one minute then Heater and pilot light go out. It will relight. Immediately, but goes out again after another minute or so. Repeat continuously until you give up. All other gas units working fine. Any thoughts would be appreciated

I had the same issue once with an Atwood water heater. The sparker is also a sensor. Heater won't fire off if that is bad. If it thinks there no flame, it will cut off the gas. I replaced mine and it still wouldn't work. I had to replace the control panel electronic module then it was fine. The sparker is obviously much cheaper to try first.

Although if you have a pilot, I guess you don't have a sparker. There may be a thermal sensor though.
