Dometic Gas Stove doesn't ignite

[Citrus breeze]

Our stove top range has a problem igniting today!  The refrigerator is working on gas.  The furnace is working on gas.  Checked the propane tank, and that is reading "green".  

Any suggestions?

[SeaDawg]

Is it just one burner, or neither will light?

Do you hear or smell any gas when you hold in the button? Can you light it with a match, but not the piezo igniter? 

Does it light, then go out? Hold the button in longer, and see if it will stay lit.

Both burners do not ignite.  No smell of gas present.  Button igniter tries to ignite, but no gas is present.  Have tried lighting with butane lighter to no avail.

Burners just are not getting any gas to them.  Doesn't seem to be a easy way to check the jets.  

Any ideas?

Has the stove worked in the past?

Are  you pushing and holding the knob in? At that time you should hear or smell gas?

If there is then flowing gas, you can then push the igniter in but need to hold the knob  in for a time for it to settle in?

When no fuel is reaching a propane burner, but other propane appliances are receiving fuel, the most likely cause is blockage in the line supplying that burner, or the burner orifice.  Have you tried CAREFULLY and gently sticking something small, metal and flexible (like an unfolded steel paper clip) into the burner orifice to see it maybe there a small piece of debris stuck in it?

[SeaDawg]

Well, still some questions in my mind before you dive into checking the jets. (In my experience,  it's highly unlikely that the jets on both burners would clog up at the very same time.) Accessing the jet is a multistep  process, and probably best done by a service tech with proper tools, if you're not an experienced rv diyer. The jet orifice is very small. (Always, if working on a gas appliance,  turn off the lp first.)

How much have you used your cooktop? 

Are you pushing  in the control knob completely, on "high" or "light", whichever setting you have, and continuing to push in while you try to light the burner?  This is a safety feature on rv stoves. Once lit, you still have to hold the knob  in until the thermocouple heats up enough to allow gas to continue to flow. (On my older smev, it's a slow count of three.) So, double safety. 

If you're following the above procedures, neither burner gets gas, and your cooktop hasn't been messed up by boilovers,  Etc., I'd open a service ticket. 

Also, please add your info to your signature,  or add info about your trailer in your post. 

Best of luck.

we had this problem when we stayed at a Peak One National Forest in Frisco CO at about 9000 feet. When we came back down below 9000 everything started working again. We opened a service ticket at the time and in the end we (and Oliver service) wrote it off to the altitude. Not very satisfying but have not had a problem since, and we've not tried using it much above 7500 feet either so I'm not sure that was the problem but it's what we're going with.

Please do not jam a paper clip into a precision brass orifice, carefully or otherwise.  You’ll create additional problems for yourself, likely expensive.  If you decide this is necessary (unlikely on a newer trailer), you’ll need a probe softer than the brass jet, think more like broom straw, brush bristle, or my favorite, a single strand from a multi strand copper wire.  I’ve cleaned dozens (hundreds?) of jets on small engines and RV appliances.  Please don’t ruin your jet by ‘cleaning’ it with a paperclip.

I agree with following up with this.

I agree that’s not a good solution.  We camped in State Forest State Park just north of Rocky Mountain National Park this summer.  We were at about 9,200’, boondocking.  The cooktop worked fine as did the fridge and hot water tank.  My Weber Q1000 fired right up as did the Blackstone.  Mike

I want to thank all of you for your suggestions.  Since the other gas appliances were all working, you were right that it had to be some problem with the gas feed for the stove alone.  Since both burners were not working, the main supply to the stove must have had an air blockage for some reason.  No, I would not stick anything into the brass orifices that could damage them.  I was about to take the top of the stove off by removing the two screws that hold it in, but I had a brainstorm.

That was, why not try my portable car vac (armorall)?  I plugged it into the ceiling circular orifice that is similar to the old cigarette lighters cars used to have back in the "good old days".  Flipped over the builtin crevice tool on the vac, and vacuumed around each burner, figuring I might either dislodge something, or even create suction on the jets.

Voila!  Both burners light...without disassembling the stove top!  

Once again, this camper is happy, and can now eat inside our land yacht!  

Again...A big thankyou goes out to all of you.

I am glad this solved your problem.

For anyone else considering using a vacuum in the future remember that they are not designed to vacuum Gas and I would be very careful of anything that may have a motor that can ignite them..... Safety First. 

Happy Trails.

Smart idea.  Glad it worked.

And, smarter than my paper clip suggestion.  Should I encounter a burner issue, I will try your portable vacuum method.

I'd probably use canned compressed air, instead. I  have used that in the past. 

Or, dismantle,  and clean jet with chemical. 

Turn off lp first.

Good thinking with the vacuum. That way, if the air movement dislodged the blockage, it would be pulled out. I tried to unblock an air hose years ago that had a dirt dauber nest in one end by hooking it up to a compressor. All I managed to do was to push the nest deeper into the hose. I was finally able to get it cleaned out with water and more air.

Thanks for adding information to your signature. I modified it slightly by adding your model year - 2021. The reason for this is since Oliver has made numerous changes in components and options over the years, when posting related to these, listing your Oliver’s year and model, and the brand of the components makes the group’s responses much more informed.
