Product review (3 stars): Wait and See
I had the leaking defrost drain/ice buildup which is apparently common with this model of Whirlpool refrigerator. Youtube videos were helpful with replacing the old grommet and installation of this new piece. One problem was disconnecting the old drain channel/trough/funnel (a black plastic piece) from the condensation pan. There is a tab on the left side that I could not get to release and ended up breaking off a small piece of the plastic condensation pan along with the trough. I snapped the broken piece back in place and it doesn't seem to be leaking. I'll keep an eye on it. Whether or not this piece will fix the ice build on the bottom of the freezer, time will tell. However, the hassle factor in terms of moving food to another freezer, etc pulling out the fridge, disassembling the back panel, working in a very tight space, is really unacceptable for a three year old major appliance. I'm done with Whirlpool and it's sister brands.
