Refrigerator & High Altitude
I've got a Dometic 2852RBX that works ok most of the time, but when I had it at 9,750' last year it kept going out and wouldn't relight. It would try, but I'd come back after being gone for awhile, or...

In case you are wondering, I was at my dealer because I was guessing the problem was a faulty regulator, but they said thats not the problem if it works fine otherwise.
Thanks.
Not sure whether this relates to your problem, but I went through a similar situation a few years ago. Frig would run for varying periods--maybe even a day at a time--then shut down with the CHECK light on. I did all the usual things--clean tubes, clean orifice, blow out bugs and webs. Installed a new Dinosaur control board, but that made no difference. Everything else worked fine--stove, furnace, water heater.
I called Dinosaur tech support to see if maybe I needed a new eyebrow board or ignitor board. After listening to the problem, the tech said his first suspicion was the regulator, and suggested I check the propane pressure with a manometer. I bought one like THIS. Easiest place for me to connect it was at the water heater. I found that the pressure was 7-8 inches depending on how many appliances were running, rather than the correct 11 inches or so. I installed a new regulator and haven't had a problem in 3 years, including trips to our favorite campground at about 6200'.
New regulators are inexpensive enough that I was tempted to just go ahead and replace it without testing the pressure, but I'm a tool guy anyway and wanted to go through the diagnostic process.
One other note--in followup emails, the Dinosaur tech thought the colder temperature at the higher elevation might have been the critical factor rather than the lower ambient air pressure.
