Water Heater lights but then stops.

My 93 Excella's Atwood WH is getting gas, and the igniters light the gas for a few seconds, but when the lighting sequence ends it goes out again. I can hear the solenoid open and close, so it seems to be working, but something is telling it to close as the end of the sequence. I tried cleaning all the electrical connections, to no avail. Any ideas?

Thanks,

Bob

If it has an electronic circuit board. It may be bad. Make sure the flame rod is in the flame. Same goes if it has the conventional thermocouple with a conventional pilot.

Try adjusting the air. Loosen the screw and slide the bracket to allow more or less air.

Thanks for the responses. The solenoid valve is closing and stopping the flow of gas, so I don't think it's a mixture issue. I will check to make sure the flame is impinging on the flame rod. Is there a way to check the circuit board?

I fumed with my newly serviced WH all weekend , then remembered the "air space" gambit. turn off water pump or city water, open hot watertap, go outside and open WH pressure release until it stops running. Reverse process. This allows an airspace to form in WH tank. All will be bliss. Sound of palm slapping forehead....

I had a similar event like that and found it to be the OPG valve on the tank had kicked in and restricted the gas flow.

I removed the tank and turned it over a couple of times and reinstalled it to reset the OPG and it worked.

I though that all you had to do was turn off the offending valve, then slowly open it. I never heard of turning the offending tank over several time. Does any body else have a different way?

Turning the tank over is the only way up I have ever reset the OPG valve. This happens more frequently than you would imagine.

There is a float on a arm on the OPG valve . Sometimes it gets stuck when cutting the flow, by turning the tank over you slosh the LP over it and it unsticks the valve.

Maybe It Needs A 'Toothbrushing'

I have had ongoing issues with the electronic ignition not sparking a flame too.
Here is what I found:
There is an igniter annode (or something like that) which causes a spark to jump a small gap and ignite the gas. It is inside the burner tube and has a wire attached to it - looks a little bit like a spark plug, which is effectively what it is I guess. I had a look and found a build up of carbon nearly bridging this gap which would not allow a spark to occur since an electrical path was now created by the carbon.
Simple fix - take a toothbrush and brush between the metal pieces which knocks the carbon off. You can see the black bits falling onto and sometimes out of the burner tube.
I am having to do this too often now and my next step is to apply some electrically conductive lubricant to the parts and see how that goes. If not better, then I guess replacement is next.
Don't spend money on the board unless you are 100% certain that is the issue.
Also, the thermostat which is spring loaded against the water heater housing and has a wire connected to it can come loose and sort of slip part way out of it's hole. Realign this if it is a problem because the thermostat needs to be in contact with the water heater tank.
Adjusting the air tube can also be helpful and quiet the burner down a lot.
Plenty of advice on Youtube about this.
Hope this helps.

Thanks, all. I'm going to try these suggestions and report back.

I had same prob. w/water heater. The regulator restricted flow and when tanks 1/2 empty would not let lp flow had to refill tanks. Solution replaced regulator, no prob. since. Very frustrating to have to refill 1/2 empty & pay for full fill up

I have a new regulator, plenty of gas flow, and the flame lights and burns robustly while the solenoid valve is open during the ignition sequence. I tried all the suggested tricks, to no avail. I probably have a bad circuit board, but will opt for a new water heater rather than spending $130 on a new board for a 22 year old heater. PPL has them on sale!!

Thanks for all your input,

Bob
