Dometic 3-way RM 2193 gas operation

Finally: She's already to go. All systems are A-OK. We've bought everything we can think of to make camping nice. We're taking off May 14 and heading (from southern Oregon) to Yellowstone, Big Horn, Keyhole State Park (Devils Tower, Mt. Rushmore, etc), the Rockys, Moab (Arches Nat'l Park), Hurricane (Canyonlands NP, Zion NP, Grand Canyon North Rim, etc.), Hoover Dam/Las Vegas, Death Valley, Mono Lake, and back home. 3-4 weeks. So you can see why I've been a bit anal about all the systems working!

Thanks again all. Very nice people here.

Cheers, Chris

Well, it turns out I had to remove the burner cover box and check it in the dark to finally see it. Good spark, lights fine, all ok. Nothing was wrong. I just THOUGHT there was. Boy! That is really hard to see....

I thank you gentlemen for you assistance.

Cheers, Chris

YEP.....thru the peep hole

Yes......if you pull the burner cover you can light it with a BBQ lighter

Probably just needs a cleaning

The spark would be at the little burner you claim you once saw through the peak-hole. Pushing the knob opens the gas valve, once lit the thermocouple gets hot and produces enough power to keep the valve open.

The burner flame is difficult to see in daylight!

The exploded view in the manual shows H and I the 'sparker' and thermocouple electrode @ the burner.

Thank you for your reply Old-Biscuit.

Yes, all electrical switches are off of course, AC & DC.
The piezo igniter makes a strong click but have no idea about the spark. Where do I look for that?
Yes, the thermostat is on high, and I hold it down while plunging the piezo igniter several times (5-10) rapidly then hold it for 10-15 secs more...as the instructions say.
Yes, the stove works...as well as the water heater.
I already have that installation/service manual.

If I can learn how to verify spark, perhaps I will do the maintenance procedures....? I saw no spark, but then again, I don't know where to look.

Can it be lit by hand?

btw: I could swear that I watched the service tech test it and I personally saw the small blue flame through the peak-hole when I bought it. This camper and especially the refer w/propane has been little if ever used. It is in VERY good shape. So, my guess is it is a very simple problem. I don't think I'm missing anything, but...I am human.

Thanks again for your help!

When you are lighting it off:
Both switches are off (AC & DC)?
Is piezo ignitor clicking/making a strong spark?
Do you have thermostat control (gas one) on 'high' setting?
Have you insured propane flow by lighting off stove top burner on high?

The main flame even when on 'high' setting is not a very large flame so it doesn't take much to disrupt it and cause problems.

I would do a through cleaning of the flue, burner & burner jet.

Here is a decent service manual......pg. 11 shows cleaning for flue, burner, burner jet......LINK
