Product review (5 stars): Fixed Freezer Leak
My problem was that the bottom freezer unit was leaking out of the front of the unit about once a day and had a half inch sheet of ice in the bottom of the freezer compartment.  After researching the issue, I found out that the reason for this issue is a clogged defrost drain plug located in the back, middle of the freezer.  Evidently, the plug that was factory installed is known to be defective and can get clogged easily leaving nowhere for the defrosted ice water to go.  This part was designed to fix the problem.  It was very easy to install, especially with the help of install videos on line, and has completely fixed the problem.  One word of caution, just installing this part wasn't enough in my case.  You need to remove the ice that built up on top of the drain plug as well.  I used a hair dryer to melt what I could from the freezer side, then pushed a screw driver up the hole where this part attaches at the top to break up the last of it.  Hope this helps someone else from having to install the part twice.
