Hey guys,

I have developed an issue with my water heater. When running on propane the flame won't stay lit. The ignitor will click and light the pilot and you can hear the flame come on. After about 15 seconds you can hear the rush of propane slow and go out. A few seconds later the ignitor comes back on and the cycle repeats itself. It sometimes will do this 10+ times in a row.

I remember a few posts a while back about the double door system used on the coach not allowing enough air into the enclousure and smothering the flame. Does this sound like the problem? It seems worse at higher altitude.

Your thoughts??

Have you tried the gas cooktop burners to see if they behave the same way?

What's the propane level in the tank? Look at the gage on the tank, not the remote indicator.

You could have the sensor thats in the flame when lit with to much carbon buildup on it clean it up. Some people have had to add openings in door also because of poor air into flame area aspecially at higer altitudes.

Unless this has been going on since you owned the vehicle, I would run the stove burners to draw gas through. I have had this happen when low on gas or just refilled and it just took some time to work the gas through the lines.

I just (I mean just - my hands are still dirty from the job) got finished replacing the electric gas valve on my water heater. It didn't do the same thing as you describe, but your problem does sound like the gas valve is not functioning right.

You might pull the connectors and make sure they're clean. And you might also rap on it when the thing is starting to stall - to see if it comes back.

I also had to replace the circuit board on mine some time back. Pretty soon, it will all be new again.

(time for me to bathe now)

Thanks guys, all good ideas. The tank is at about 72% full, and the range burners all work perfectly. The gas valve is a thought. I wasn't sure what the circut board would do if it was going out. I will have to try a few different things.

Check your flame, it should be a nice blue. If not, try adjusting the air flue on the burner tube to acquire a blue flame.

Remove and clean (pencil eraser) any/all connectors on the circuit board also.

Same thing happened to us in the TT last year - I had to close the mixing tube down, a bit like adj says above. I have also heard from a few others that have run into this, and theirs ended-up being a loose wire connection onto the circuit board.
