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...

Some Dometic models have no thermocouple, but if yours does, testing is easy- just measure the voltage it puts out in the flame. For the non-integrated igniter boards, the thermocouple needs to put out above 15 mv, with ~25-30 mv being the norm.
For the integrated igniter boards, where the spark wire goes right to the main board, there is no thermocouple. Flame sensing is done purely through the electrode and flame itself.
I've thought a lot about hi altitude operation- never been able to get what I feel is a good answer. The trouble is, if you say there is less air so I need a smaller orifice- all that does is get you a smaller flame, still starved for air. Because there is no air adjustment on these, and all models actually use the same burner with different orifices, I just don't know how to solve that problem. It could be that a *higher* lp pressure would pull more air in to the mixture, but I would want to do quite a bit of experimentation.
Sounds like a tax deductible vacation to the high country is called for :) (I grew up in Colorado).
