Yep -- odd thing is that now with the pressure adjusted correctly, the
flame looks very weak, absolutely no cooling, and the flame LED is
very dim -- I have the blue LED modification, which makes it fairly
easy to judge flame intensity.

I have yet to pull the fridge again, but am thinking now that it's
likely to be a clogged jet?   I had replaced all the gaskets with high
temp RTV so I'm 99% sure it's not an air leak.

Is there a way to pressure test the LPG coming out of the dometic
thermoregulator?  Or is the test basically to see whether the flame
looks proper size/shape?
