Help, Help! We are set to take off Tuesday morning. Just got the trailer back from the shop on Saturday and we're busy loading. Went to turn on the frig and it won't light. We're not on shore power and no way to do that. We got new propane tanks but otherwise nothing was done to the gas system. There is power to the frig and propane is on and flowing since after a few minutes wait the stove lit. We turn the frig on, on auto and we can hear the clicking outside with little "bursts" of sound but it doesn't catch and goes back to clicking. We've been at this awhile with no progress and don't know what else to try. Help!Bob

I don't know why this works for us, but anytime we have turned off the propane for any reason - when we turn it back on we always light the stove first and let it burn for about 20 seconds. Even then it takes the newly turned on propane a few seconds to reach the stove. We don't turn the burner on high to light either. Usually.. we turn it to med or low. You're sure you have the right tank switched on.. yes? If we don't do that we've noticed the furnace takes multiple tries to ignite, and yes..sometimes....the fridge auto light has bounced back and forth between gas and electric. Not sure that's your problem, but it sounds a bit like what we go through. Good luck!,,

As suggested.....light the stove top burners. I always turn them on high to get propane flowing thru the lines.Then turn fridge on.......may have to reset it a few times until propane flows for fridge lineThe propane lines probably just need purged with good flow of propane And make sure you have a good charged battery......need that 12V

Did it light yet???I agree with all of the above-and you'll have to manually switch it back and forth as it eventually gives up the gas...

I read that you already lit the stove and it worked, so there is flowing propane. Might just take a few more than usual tries since the tanks were replaced. I assume that you know that the tanks are full?

Thanks for letting us know how it was resolved. Simple and inexpensive is always the preferred outcome. :C

Final answer: Thanks to all who tried to help. The simple problem was that, in fact, the igniter is the thermocouple and it was not far enough into the flame to get hot enough to keep the gas valve open. Took to dealer, 10 minutes, no charge. Leaving for South and then West in the AM.

Take a wire brush and clean the build up off of the igniter.

As robsouth said, themocouple. If the thermocouple doesn't "see" a flame the gas valve closes. On many older units there is a seperate thermocouple, on newer unis the igniter senses the flame.

Thermocouple? Just a thought.

Did you clean out the burner? They get filled with crud.

Thanks to all who are trying to help me. This morning I called Dometic and they advised me to just keep cycling it until the gas flow was steady. I did that a few more times with no change so I disconnected the igniter and removed the gas pressure test plug. This allowed a higher gas flow to purge the line. Hooked everything back up and cycled the on/off switch but there was still no change. Good spark and then brief blue flame and then out. Tomorrow I will have it back to my dealer first thing. Does anyone think it could be the circuit board? The frig is only 5 years old. I have electricity, spark and gas flow.

Other thing I can think of is the battery. If it drops below 9-10 volts, the refrigerator control board will not ignite, and it will turn on the check light.

Did you look for a Reset button? Some models of Dometics have one, usually Red in color. Good luck.
