Dometic Flame out

I have a Dometic 2193 frig in a Rockwood model #1980 pop up camper. If i tow with the gas running the frig, the burner blows out within 5 miles. How can I stop this flame out situation,

A few pics would help but like Greg said, probably a missing or mislaigned shield.

As a prior pop-up owner, I found the same problem.

My unit also ran on 12v, so I would choose this option when towing. The
12v chargeback line on the tow vehicle would keep the pop-up's battery from crapping out.

I'm not certain if yours has the 12v option, but it worked well for me.

I would recommend using the 12 volt option while towing. As long as the refer is already cold it will maintain the temperature. My specific reason in that you don't have to remember to turn it off and relight it when stopping for gas.



It also saves the hassle of having to turn it off if you are going through a major tunnel where you have to stop for inspection and turn off the gas at the tank.

I know this advice does not resolve your problem of why the refer burner is blowing out. You should still look into that as you might experience the same problem if camping in a high wind area.

If it is blowing out because of wind while going down the road then put a standard furnace filter of the appropriate size behind the outside access door. An old and very little known about RVrs trick to fridges blowing out....

I would think about this one, why put something flammable in this area.

Furnace filters do have a cardboard edge but the rest is non-flammable fiber glass
and a little tin.
The flame on an RV fridge is small and shielded.
A furnace filter would not bother me if it kept my food cold!

I used to tow a previous trailer with the refer on DC mode until I discovered
it was sucking the juice out of my trailer battery while I was on the road.
And yes, my truck did have the 12v battery lead connected in the plug.
It's just so far down stream from the engine alternator that it was still able
to discharge my trailer battery.

If you what to keep your food cold and the flame is shielded then there is no reason to place a filter in the out side compartment. The fridge needs air flow to do it's job. The air is pulled in at the side vent of the fridge on the outside of the camper and then vented out though the chimmey that is on the roof of the camper above the fridge, the heat from the fridge is very warm. If air is restricted then it will take longer for the fridge to reach it max cooling temps. Some people install a small electric fan in the top of the chimmey to speed up the process. If the flame is blowing out while traveling, then there maybe somthing wrong with the shield it self or maybe a problem with the ragulator. I would have it checked and repaired and not make modifications.

The flame is shielded as stated above by a metal enclosure the problem especially in high side wind conditions is that enough wind coming through the access door can and does very often blow the flame out. Putting a furnace filter behind the door does not place it in close proximity to the flame. We have used this trick for over 30 years without any dangers on sevral different rigs.
