My 95 EVC came with the infamous Model 3163G refrigerator. Mine would not
cool below 50 on LP. The RV tech replaced the igniter, burner, cleaned the
chimneys, and adjusted the flame, and then it would not cool below 40. I
added insulation to the output tube from the combustion chamber, and cut
an extra ventialtion hole in the grey side panel, and got it to cool to
35; all being done with the ambient air temp at 70. Mine does not have the
high-altitude kit.
        Imagine my surprise, when the fridge worked perfectly up to 9000'
on our last trip. What I learned was the cooling on LP is sensitive to the
outside temp, at temps around 90, it would not cool below 50, but at 65,
it cooled to 34... all with the thermostat set on 5 (max). I think that my
flame must be set lower than others, so that my unit requires less oxygen
and thus is not so altitude sensitive.
        What do others think?
