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...

The Dometic orifice is a laser drilled synthetic gemstone, and the hole is actually rifled, which is supposed to spin the gas to pick up the proper amount of air- this is how they get away with having that big gap between the orifice and burner.
That said, I do not believe that a smaller orifice will get you anything- the same sized burner is used in nearly every model, with the only difference being orifice, and I do not think the smaller models are any better than the large ones at altitude.
That said- I would certainly give the burner a good cleaning and soak the orifice in alcohol and air dry, and if your model uses the integrated ignition board, which doesn't use a thermocouple, I would make sure the electrode is centered over the burner with a 3/16" gap above the burner. A lean flame will be harder to detect, so electrode adjustment is critical.
