Product review (4 stars): Functional Replacement at a great price
The icemaker and parts received matched the photo and description exactly.  I'm not at all sure that the icemaker is OEM (original equipment manufacturer), but it was an exact fit for the old one.

The replacement (after watching the installation video online), took me about 30 minutes.
1.  Unplug the refrigerator, or turn off the circuit breaker.
2.  Loosen the top two screws, and remove the lower screw.
3.  Lift the old icemaker off the two loosened screws.
4.  Unplug the electrical connector (push in on the white clip, or it won't release).
5.  Remove the wiring harness from the old icemaker (you have to remove the front cover to access the white clip first).
6.  Move the steel clip on the new icemaker to the same position as on the old icemaker.
7.  Install the appropriate wiring harness on the new icemaker.
8.  Carefully cut out the 'cut-away' hole for the water trough (see old icemaker so you know which one to cut out).
9.  Install the bottom bracket on the new icemaker.
10. Attach the new icemaker wiring harness to the freezer wiring harness.
11. Hang the new icemaker on the loosened screws.
12. Tighten loosened screws and install third screw on newly installed bracket.
13. Insert on-off arm in correct slot, and swing down.
14. Restore power to refrigerator.
15. Wait.  My untit took 90 minutes to create the first bactch of ice, and made one batch every 60-90 minutes for 36 hours until the tray was full.  Success!

Overall very happy with the new replacement unit.  We'll see if it lasts as long as the first one!
