Product review (4 stars): Square connector was the difference....works great!
This ice maker was the second one  had purchased.  The first, although it was advertised to fit my Kenmore Elite, side-by-side with the bottom freezer but...the connection was an in-line connector versus the square connector that my freezer required.  Plugged it in, turned it on and within 24 hours had a bucket of ice ever since.
