Dometic Refrig not lighting at altitude

Used mine in Colorado this summer at up to 9800 ft and had no problems. Might want to check the regulator on the gas.... Had mine go bad once.

I had the regulator checked to 11 pounds and it would not light at 7500 feet. I the was told to get it adjusted to 13 pounds and it would now light at 7500 feet but I now have a constant popping sound in the flame!

I recently replaced the regulator for ours and the refrigerator worked much better this trip. While the line was disconnected, I also disconnected the refrigerator end and used some air to blow the line out (from the refrigerator end). If you do this, make sure the tank end is in a bucket or something as I got a significant amount of oily liquid out of the line.

The stove, water heater, and furnace each have a larger orfice than the refrigerator. On top of that, none of those has a pilot light so the gas flow for any of those is larger. I was mainly concerned with making sure there was nothing in the branch leading to the refrigerator which was why I blew air through from the refrigerator end. Also, since none of the other branches had anything turned on, there would have been pressure there to help keep stuff from going into those branches since the only openings were at the refrigerator (pressure source) and the regulator end (pressure relief). Since doing this and replacing the regulator, my refrigerator has performed much better this summer than last summer.
