Last time I had to pull fridge, due to propane hassle, I discovered that
the 12 volt element was loose in its pipe.  I fixed that, but haven't
bothered to check to see whether it works any better, because I'm one of
those folks who are addicted to propane while running or mains power inside
the carport.

2 out of 3 is a winner, in my book, and I wouldn't bother to pull a fridge
unless something's seriously wrong or you're masochistic.

If you do decide pull the fridge, you'll be amazed at the sheer volume of
schmutz that you'll find inside the cabinet.
