Product review (5 stars): Make Sure to Synchronize the New Ice Maker After Installing!  Works Great!
My icemaker had been working erratically for several months and I was constantly turning it on and off and emptying the ice when it overflowed.  Often, there would be no ice at all.  Finally, the icemaker just quit.

After looking at videos on YouTube, I decided that the icemaker itself had died.  I ordered the replacement and it took about 20 minutes to remove the old icemaker and install the new one.  The only tools required were a phillips head screwdriver to remove the two screws from the top and the green ground wire screw.  Upon powering up the new icemaker, the lights came on but there was no activity after about 20 minutes of waiting.  Turning the power on and off did not help.  I discovered that there is one important step that is missing from the videos:  In order to resynchronize the ice maker with the rest of the refrigerator, it is necessary to hold the ice cube size button down for 10 seconds.  This forces the icemaker to go through a full operational cycle and will synchronize everything.  You can watch the ice ejector turn a full revolution, the ice sensing arm will move up and down and the tray will fill with water.  After that step, everything is working great and we have ice again!  Well worth the price and most owners can absolutely do it themselves.  See the photo for button location.
