Fridge won't work at altitude on propane

[cliftonda]

I have a 2016 Winnebago Vista 31BE with a Norcold fridge that works fine on propane until we take it anywhere above 6500 - 7000 ft. It works at those heights if plugged into electric, but never has when we try running on propane. Since we live in Colorado and like to go to the mountains, this is really a nuisance. Any suggestions?

Adjust the air/gas mixture for that altitude and then place a mark at that spot for future trips.

They may have a high altitude kit for it maybe which I think is just a smaller orifice though if the fridge has the capability to adjust do that as previous poster mentioned to much fuel not enough 02 to get it lit or keep it lit. Had that problem with a popup trailer water heater here the high altitude kit helped to about 9k elevation as long as the wind wasn't blowing to hard.

cliftonda, I have cleaned and adjusted the electrode gap and it seems to help at high altitude .
"Electrode tip-to-burner air gap should be between 1/8 to 3/16 in."

This is a normal problem at high altitude...................

Thank you all for your suggestions and input. I haven't had a chance to work on it yet but will let you know if I find anything.

Propane regulator controls to 11" which give correct gas flow at lower elevations. At higher elevations air pressure drops but regulator stays at 11" resulting in a lower pressure differential and thus a higher gas flow. Couple this with reduced O2 at higher elevations and you are fuel rich, thus it won't burn. Probably need the high elevation kit that was referred to.
