Product review (5 stars): The replacement ice maker is a perfect match for the original unit that lasted three years ...
The replacement ice maker is a perfect match for the original unit that lasted three years in our 22.6-cu ft. side-by-side 33-in Frigidaire refrigerator.  The old unit's controller started misbehaving by not ejecting the ice cubes, unless the maker is turned off and then on.  In any case, the new unit is a perfect fit for the old one.  It came undamaged in two days and installed quickly in about 30 minutes.

The procedure for removal of the old unit and installing the replacement is straightforward.  You only need to deal with three 1/4-in sheet metal screws and a 4-pin connector.  Remove the ice drawer by raising the front end and sliding it out.  Remove the accessible front lower screw.  Since space is tight and it is not easy to see the upper screws, a mirror placed strategically (see illustration) will help you guide the -in hex screw drive with a long (about 4 inches) extension to loosen the upper screws just enough to slip the ice maker up and pull it out through the enlarged hole space below the screws.  Once the connector is exposed and accessible, squeeze the two prongs on either side of the female connector attached to the maker and pull it from the male plug part that comes out of the back of the freezer.  Do not worry about matching the pins again when you reconnect your new maker, since there is only one way the connector ends match.

I had great satisfaction to be able to replace the maker with little Hassel and cost.  I hope you do too.
