Product review (5 stars): Improved performance and reliability
I got this ice maker as a replacement for the flaky unit in my LG french door refrigerator.  Mine failed to add water at the end of cycle of ejecting ice cubes.  [Note that this can also happen because the solenoid that opens to allow the water in does not function, but mine was recently replaced and worked ok.  This valve is located behind the food bin under the entire ice maker housing].  Replacing the unit requires a Phillips head screwdriver and a bit of dexterity. Remove the ground-wire screw under the back left of the unit.  Then remove the back upper right screw.  Finally remove the upper left screw and support the unit in your left hand.  Tip the unit forward and unplug the connector (note that there is a locking tooth that has to be raised by pushing down on the end of the connector).
Hold replacement unit in left hand with thumb on top and palm against left side.  Tilt it 45 degrees toward the front and hold out it out to the left, then raise toward the wiring plug.  Approaching from this angle you can see the receptacle and the plug as you line it up to push it in.  This requires holding the plug in the right hand and twisting the top of the plug toward the front to align it with the receptacle.  Replace the upper left screw. then the right, then the ground wire screw.  This updated ice maker stores the bar that detects when the ice bin is full under the unit, rather than sticking out at a 45 degree angle as in the original.
