Really --- your best bet is to pull the fridge and check it out/clean it up.
I find I have to do this about every 4 years or so. Here's a link to Frank
Condelli's instructions: http://members.aol.com/Fkc43/fridge.htm which I
have used happily a couple of times. While you have the fridge out you may
well find the reason for the smoke --- and the cleaning you do will almost
certainly make your fridge work better --- and it gives you the chance to
upgrade the noisy and stupid stock cooling fan.

Cheers,
Doug
