That's a great question. I've read on-line that it's meant to be the pressure while running, but that was not from the manufacturer. The only thing I can find in the Dometic installation manual is: "The gas supply system must incorporate a pressure regulator to maintain a supply pressure of no more than 13.5 inches water column, static (no load)". So there is a fair amount of latitude between what we all hear about 11" and what Dometic says is the max with no flow. On both our Casita and on the Escape, I had to turn the regulator adjustment quite a bit to even get to 11". It would be really helpful to talk with an actual Dometic tech to find out exactly how they intend to set the pressure.

This is off the Dometic site but may not be your exact refrigerator.



The LP gas pressure should be checked and the main
regulator readjusted if pressure is incorrect. The cor-
rect operating pressure is 11 inches of water column.
The correct place to take the LP gas pressure is at
the test port just ahead of the burner jet. (See FIG. 12)

I would interpret operating pressure as running pressure. Everything we work on we adjust while it is running and check it at the unit. I cannot get the picture to copy but shows taking the reading at the test port at the refrigerator while it is running and that’s what it is saying. Probably why they want it at 11" instead of 11.5".

That's pretty clear. I'll give that a try. So far, I can't tell much difference between propane, 120V, or 12V in terms of cooling. With both our small units in the Scamp and Casita, propane was much more effective than either electric option. I suppose if it's still low on this one, it could again be more effective if cranked up. Thanks for digging that up.

I can't answer that but I adjusted mine with the refrigerator running to account for the pressure drop. I believe it drops about 1/2 of a number. It is adjusted at 11.5 while running with everything else off.

For people with a 19 and side vent at the top of the refrigerator, here is some news about a new baffle. This was installed today by our Dometic service center (and RV dealership). This is another attempt to cure our 5 cubic foot refrigerator, and get it to cool while being towed. It is a piece of white aluminum custom-fabricated to fit our Escape 19. The theory is that air may be entering the top vent at highway speed, preventing the warm air from leaving the refrigerator coils. This baffle is meant to redirect the air away from the vent and create a "wake" (low pressure zone). We'll post again when we have data. We'll post some pictures on our blog. --Jay and Liz

"The fridges are now vented out of the top on both the 19' Escape and the 21' Escape and Reace has recently changed the baffle in hopes of improving circulation."

Tammy just sent that to me. I was thinking that perhaps it is a problem with the large frig, but it seems from this thread that folks with the smaller ones are having the same issue.

Terry just reminded me that when we traveled in the airstream with a dometic frig we weren't in particularly hot places.

I can't find where the small fridge was talked about being a problem but I'm a little slow sometimes.

Look back at my original posting. I included a link to the other discussion, so I could try to have this thread focus on the 6.7 cu ft model. I'm not sure there is a widespread issue with either one. It seems that some people do fine with the 5 cu ft model and others have all sorts of strange things happening. Apparently there aren't enough 6.7s out there to get any sort of consensus, but I understand Reace is engaged in trying to improve its operation. That's a huge benefit, having the owners using their products and experiencing some of the same things we are.
