Product review (5 stars): call Whirlpool
My bottom-freezer fridge began forming the ice rink at the bottom of the freezer, AND my ice maker stopped working at the same time. Began the research, watched a bunch of videos, was ready to do the repair myself, leading me to this product on Amazon. I called Whirlpool, and even though my purchase date was over a year ago (by about a month and a half), they said I fall into a "grace period" and that service was still under warranty. Glad for Amazon's review and comment feature!
