I had to replace the cooling fan, which meant I had to yank the thing.
It came out okay (with help from the list telling me how to do it).
Along the way I had to replace the inlet pipe for the propane (my local Ace
Hardware made it for me right on the spot!)
At that point I hadn't read about cleaning out the combustion chamber (this
was to appear a few days AFTER I had the fridge back in place!)
Yesterday I blew it out with a compressor (shooting down into the exhaust
pipes, and up into the drain).  I fired it up and it did fine, I could feel
heat coming out of the flue, hear the flame churning away, the needle pegged
all the way to the right in the green.
I drove a few miles (5) and the flame had gone out.

And the answer is: (?) [awaiting the clattering of keys by the pros here!]
I know, I know, it's probably back in the archive somewhere.
Oh yeah, Is there going to be a compliation of the many tips and hints about
Dometic fridges??
