make sure the water runs off properly when defrosting .
there should likely be a bit of water in the pan at the bottom underneath the fridge - that shows you it's actually defrosting properly .
clean the coils underneath while you are at it - a lot of dustbunnies can collect on the coils .
there is a special brush you can buy to get into the narrow crevices - but DO NOT shove the brush in or the coils might break .
our fridge will "freeze up" when we've been away for a few weeks and i have a special procedure to make the water run again :wink:

cleaning the coils will save electricity !
