Just got back from a camping trip where my Dometic fridge did not work on propane. Made the repair myself at camp. My fridge works as follows:

If fridge is warm and you first turn it on in the gas mode, you will hear one large click which is the gas solenoid opening followed by some quieter faster clicks until the burner lights. In my case the gas solenoid opened but no igniter clicks. Found oxide on the igniter rod at the burner and clean it off with steel wool. After cleaning it the fridge lit first try.

If you don't hear the continuous clicking sound when first turned on in gas mode, your igniter is not working.

Thanks, johnnyslick. After doing several different tests ourselves, we talked to a gentlemen from Dometic today who said he believe we need a new igniter. (We never hear any igniter clicks, just the first large click.) It is going in for warranty work tonight. Glad you were able to fix yours! Thanks again.

Definitely a faulty igniter. Covered under warranty and all is well. Thanks so much everyone for the help!!

Check the Propane regulator. When ours did the same, we found our regulator faulty, replacement cleared the problem.

Push the red button between the wires.

I pushed the button and no results. I cleaned the igniter and no results. It appears that I am not getting any current to the igniter. Does this mean that my board is bad?

Sounds like a tech job, just let us know what the fix was. Thanks.

Make sure that your battery is fully charged ---- it's a 12V igniter.

Batteries at 85% (12.5VDC). Burner works fine when lit manually. Everything works fine on AC.

the one large click is the gas valve. it should be followed by numerous little clicks of the ignitor. ive seen carbom build on the porcelain of the probe and it just carbon track with no spark but this is a new unit. the module works by building voltage till it discharges across the gap.

I already checked and can't find parts for the new Dometic 702. Had the dino board put in an old Coleman and it worked great until the igniter board gave up the ghost. Nothing like a trailer that is old enough to buy you a beer.

The newer frig. is gonna be a hoot until parts are available. I don't own one yet and am almost afraid to trade as my current rig works.

My problem ended up being the circuit board. Burner would not light. New board and all is good.
