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...

Cleaning it didn't fix it. I was at around 9k last weekend and same problem. Here is what it does when trying to run on propane and the problem arises when it tries to light.
It'll light, but it will keep sparking the ignitor (even though I can hear it burning). It'll continue to spark the ignitor and after a short while, it'll stop sparking it and I think it then closes the gas valve, so the pilot goes out. Repeat, repeat, quit.
I've got the wind covers off again and thinking the probe that sticks into the flame must need to be lowered or something. Its the only thing I can see that senses temperature (ie.. that would tell the unit that the flame is lit...but if this is the problem, why the flame isn't as hot at higher altitude is a bit of a mystery to me.
It's important to know that the thermocouple isn't the only thing that senses whether the flame is present, the igniter itself performs this function as well. The continued sparking makes me suspect this part of the circuit. I believe it works by measuring the conductivity of the flame, and the altitude might affect this somewhat. You may need to adjust the igniter, replace the igniter, or replace the board. I recommend the Dinosaur Electronics replacement boards if you get to that step.
