Product review (5 stars): Fix for Warm Fridge and Frosty Freezer
Our fridge was about 50-55 degrees and we were getting tons of frost in the freezer.  The OLD motor/fan in the back was quiet (no bearing sound), but too slow.  It barely blew.  Put this NEW motor in and it blows SOO much better.  Now our fridge has settled to 35 degrees and everything works well.
It is easy to change just the motor and keep all the other parts for cheaper.  You just pop the assembly apart (white piece and black piece) after removing it with two screws from the back of the freezer.  The fan just slides of the shaft of the old motor and onto the new.
