I had a dometic that wouldn't light the other day.  Hadn't worked in years.
Before ripping it all apart I unscrewed the plug in the drain right below
the fridge door and blew some compressed air in there.  After this the
fridge lit right up and works very well.  I could hear the thing popping but
it just wouldn't light.  This might not work for everyone but it is worth a
try before ripping everything apart (BTDT).

Hope this helps,

Thanks for all the suggestions. I pulled the fridge and checked the
combustion chamber. There was a little bit of gunk and rust in there, but
not very much. I cleaned it out. I also blew as hard as I could through both
flue vents. I put it back in the cabinet and It ran for almost a day on
propane with the thermostat at MAX before I shut it off. So, the problem was
either in the flue vent system or the combustion chamber. My guess is that
one of the flue pipes was blocked which allowed enough fresh air for the
pilot, but not for a bigger flame and so it went out when the thermostat
knob was turned up.

While I had it out I took the insulation sleeve off of the flue pipes. I
couldn't remember if it was supposed to wrap around both pipes or just the
exhaust. I couldn't get it to wrap around both, so it's now just on the
exhaust pipe. I hope I got that right.

yay!
