Product review (5 stars): It was also pretty easy to install
My freezer on the bottom Amana would consistently create a giant sheet of ice on the bottom of the freezer which then leaked all over the place warping my floor.  I swapped in this replacement drain tube which acts as a trap and my problem immediately and completely disappeared.

It has been a few months now...and I can say that this fix worked 100% for me.  It was also pretty easy to install.
