Product review (5 stars): Easy to install & fixed my problem!
If you have a bottom freezer with a drain that freezes up and you get ice/water in the freezer - this should fix it.  Pretty easy to install.  Only difficulty I had was removing the old tube.  There is a tab on the bottom fitting that you have to push in with a screwdriver to release the catch and get it loose.  Kinda awkward to get both hands in to push the tab on one side and pull up the tube with the other hand.  Just be careful to not break the fitting in the drip pan!  I put this in a month ago and the drain is still clear.  Plenty of youtube videos, search for the part # W10619951.
