So I have a popup camper too, with a stove that moves from inside to outside. How nice since there are gas lines in both spots.

I hook the stove up, push the button down to lite, and try to light the burner. Nothing. Check that all valves are open, gas tank full, furnace works great. Nothing.

Take the stove unit, apart and this is what is under the top plate.

Curious about this design. I was going to say that I'm not chemist but, I am a chemist and gas doesn't follow a path that is open.


Pressurized gas at a high velocity however does "follow a path that is open" and shoots by those open spots creating a vacuum, siphoning the correct amount of air and mixing the gas and air at the same time to the correct ratio to burn correctly.

This isn't a "chemist" thing..

If stove works fine indoors but not outdoors you could have several things causing that..

#1, do you have gas at the connection?

Do you smell the odorant that is put into the propane when stove valve is on? You should smell it when not lit..

Sometimes you may find a shutoff valve inline with the quick disconnect, it may be turned off as a default for safety as quick connects sometimes leak when not connected..

Quick disconnects can also fail to pass gas when connected, did it ever work?

#2 too much wind?

While the burner and air gap may be protected from the wind pretty well, it doesn't take a lot of wind getting around the protection to prevent proper fuel to air mix. May need to create an additional wind break to shield stove in that case..

1. You DO HAVE a regulator. Period. While you see the Tank hose at the tank, there IS a regulator connected to that hose.
2. The Gas line at the pic of the Range, that silver thing is the Range Regulator and it is there to drop the RV LP pressure from 11.5 inches to 10 inches which is what most RV Range/Ovens operate at.
3. Clarify, IF the Range is inside the RV in its mount hole does it operate and light OK?
4. It only fails to operate correctly when mounted outside?
5. If mounted outside, can you light the burners with a match?
6. Last, from your pic, there does NOT appear to be a Piezo or auto ignitor system. Your Range must be manually lit with a match or flame. Doug

A lot of people, including me, give up on the portable stove that comes with the camper.

Think about a Weber, Coleman, or similar portable camping stove. You may be happier in the long run.

3. Inside or outside, the gas does not make it to the burner. When I light the gas at the knobs, it lights, but very weakly. There is no hiss from even the opening at the knobs.

FYI, I had a problem with my popup when I tried to use the stove outside. Thanks to lousy design, the hose was connected to a pipe that came straight up from the floor, and it made a 180 degree bend. Routing the hose to the outside the hose would kink and cut off the gas. I had to add a 90 degree elbow fitting to keep the gas line from kinking.

Since the furnace works it's possible you have a clogged or pinched gas line or the regulator in the stove is shot.

Maybe the orifices are clogged, or maybe the stove's regulator is being very much overzealous (or otherwise having the gas supply constricted). If all the burners are behaving identically, I'd tend to suspect things common to all three.

I assume you have a spring loaded LP quick connect. It is probably the Center pin inside the quick connect is NOT seating squarely and pushing the inside pin inward to release the LP. You need to remove the FEED fitting(LP turned OFF at tank) and then have someone open the LP tank valve. If you feel and hear a good stream of LP the quick connect is your problem. Doug

PS, VERY common problem when trying to use the outside LP connection, very strange it also fails inside.

If that is a regulator where the copper line is attached, you cannot have two regulators, one at the tank and another in the stove. Possibly the wrong stove was supplied.


Not necessarly true
The RV has a primary regulator 11" of water is the pressure
And the stove often has a secondary regulator at a LOWER pressure.

To the original poster
First follow the lines to insure that both are low pressure ports (I suspect they are but check to be sure) also inspect the lines to the non-working port.

Then it is possible the external port has an issue.
