I was able to fix my fridge blowing out problem by sealing the flue.  I
don't know which interface seal was the problem because I sealed them all,
body to rubber gasket, rubber gasket to plate, etc. etc. all the way out.  I
used a light coating of clear silicone so that it would be easy to remove
later if I wanted and you couldn't see any of the silicone so no worries
there.

Don't forget to seal your utility inlets if you haven't already.
