Product review (4 stars): The new one snapped in pretty easily.
Hopefully this is the first and only time I ever have to work on my fridge.  I replaced the factory part with this one to stop ice damming up inside the freezer drawer and leaking water all over my floor.  The part is well made, but instructions are a bit sketchy on how to actually remove the old one.  I ended up just getting physical with it by using a pair of cutters to break it into pieces.  The new one snapped in pretty easily.
