Dometic propane stove/oven won't light

What you are describing suggests that the wires for the sparkers are missing. I suggest that you post some reasonably close pics of the stove with the cover removed. That might help us sort this out.

Here is a pic of my stove with the cover removed. There are three black wires going from the backside of the piezo electric generator, one to each burner. There are standard lugs on back of the sparker and one on each burner the the wires connect to. The actual sparker on each burner is a small ceramic post with a smaller metal post sticking out of it when you turn the knob on the sparker, a spark jumps from the metal post to the body of the burner. Whatever burner you've turned the gas on for should fire up.

I've attached 2 pictures. Only 1 wire which is on the far right and is for the oven. It won't light either.

If you look at the description of her range in the link she posted it says, "Match Lit Burners." Don't know what that extra knob on the far left is for but it obviously is not for a spark lighter.

You need to find another angle to look at.

Does your water heater work on gas? Does your furnace work? Does your refrigerator work on gas? If those are all "yes," then you have a gas flow problem at the range itself.

If none of those work and you know that you have propane in the tanks then I would be very suspicious of your pressure regulator.

If you will read the full description of the stove, it specifies "piezoelectric ignition" as well as match lit. The pic posted does not include the sparker knob and the mechanism behind it like my pic does. It would be helpful to see that part of the stove a bit better.

If there is no piezo to the burners, then gas flow becomes the primary suspect.

The OP's piezoelectric sparker is for the he oven.

Y'all do realize that with or without the little sparky thingy... if there is propane a match will light the darn thing...

LOL! Only because I now have to manually light every stove burner and the oven. How I gained power everything in my Hideout and lost the push-button spark-o-matic in the Nomad is a mystery. Even the Santa Fe had a central pilot light with tubes running to the stove burners. Now I have to flick a Bic.

Actually, I go retro using an old flint sparker to light the stove burners (similar to image). My parents used it in the early 70's and it still works like a charm. Oven still requires a match or butane lighter.

There is no extra knob, she has three top burners and a oven temp controller, that makes 4. The stovetop with a sparker has 5 knobs.

Yes, all the other propane appliances work.

Propane has a distinct smell, and since you don’t have a manometer to test for gas pressure at the burner, try this:



TURN OFF ALL LP appliances. Then using two wrenches, lossen the flare fitting on the top of the stove. You should smell propane if it’s flowing. If you do smell propane IMMEDIATELY TIGHTEN the fitting. Your problem is the regulator on the stove. If you don’t smell propane, then there is a problem with the piping to the stove. Let us know what you find. Open windows and air out the trailer for 30 minutes.

[kathyTerry]

Ok, yes he smelled propane and so we're looking at replacing the regulator. Thank you so much for all the help! Apparently our water heater does not work on propane either. We've used it on electric and never tried using it on propane so he checked it to see if it worked on propane and it does not. There's propane coming to it but it doesn't work. It's not a major problem. We live in FL and when we camp, it's 99% of the time at state parks with electric.

[kathyTerry]

I want to thank everyone that tried to help us. My husband originally thought it was the regulator but wasn't sure. Thank you all. You guys are great!!!

[chuckster57]

Water heater- make and model, let’s see if we can’t get that working too. You never know when the park might lose power and you need LP to heat water for dishes/shower.

[kathyTerry]

Terry says there is propane to the water heater and the igniter works but it won't light. There's no propane coming through the regulater. He tried a lighter and it wouldn't work.

[ctbruce]

I know there has been a lot of input on your issue, but some of the best advice was given in post #11. Did you try those things yet. If yes, then probably the regulator. If not, then try this before replacing the regulator.

Not common for the gas valve to fail on a water heater, but it sort of sounds like it. To be sure, simply turn the Water heater on LP and then using a test light, check for 12VDC at the gas valve. If there is then most likely the valve. If. Or then most likely tihe control board.
