Product review (5 stars): Perfect Solution for Top Cold Freezer and Bottom  Warm Refrigerator!
This item was delivered promptly.....Did the job....Saved a service call on a refrigerator that iced up on the freezer coils and caused the refrigerator to get warm....Once this item was in place the heating coil (previously tested OK with ohm-meter) heated up and defrosted to prevent the ice buildup.
