Product review (4 stars): More than just replacing this part
I  installed the drain replacement and time will tell if it allows the defrosted ice to flow to the evaporator tray. The old flume was frozen in the tray and part of the tray that hold the old and new part broke. The new part installed just like it was shown in the instructions, easy if you have good access to the rear of the Refrig. You still need to clear the ice behind the metal backing of the Refirg as well as clear the drain hole of the ice. If you don't then you will still have water flowing out of the freezer when it is defrosting. There are video on the web" You Tube" on taking the freezer door off and removing racks and panels to get to the drain, drain tray and coils to melt the ice. You may want to consider outside help for the defrosting. After studying the videos it took me about 2.5 hrs to do it all. Good Luck You Do It Yourselfers.
