82 diesel Westy, stock everything.

PO said he didn't use fridge in his 12 years of ownership.

Surprisingly it works "great" on 120AC.

Pumped up the propane 20-30 times, clicked the button 5 times, and
voila! the propane "works."

But, I'm concerned about the exhaust.  There is just the tiniest stream
of heat coming out of the exhaust, while there is quite a bit of heat
coming out of the interior vent on the left side of the fridge near the
back.  Is this normal?  I'll probably pull the fridge anyway.

Also, someone had mentioned blowing some compressed air in to clean the
fridge, where does it go?

And, what is the little tube with a plug in it sticking out from under
the fridge?

Thanks!
