Product review (5 stars): Makes Good Ice and Easy to Replace
This has been making good ice for 3 weeks now, working flawlessly.  Seemed at first a bit slower in making ice than my 1st ice maker which failed after 17 years.  I turned down the temp in the freezer which is one of the things you need to do to make sure the ice maker gets cold enough to make good ice.  That helped quite a bit.  Plus I'd imagine the unit needs to cold-soak in the freezer for a number of days before its best operation.  The 1st replacement I ordered came with broken parts but it was easily returned.  This one is running like a Champ so far, and I hope it lasts as long as the original!

To replace, LOOSEN do NOT remove the (2) screws holding the icemaker to the fridge wall.  Lift the icemaker with its slotted brackets up and away from the mounting screws, and undo the electrical connector as you go.  The connector has a couple of prongs to squeeze-in and release.  Installation is the reverse of disassembly.  Don't forget to unplug the fridge before you start!
