Product review (5 stars): Good Design Change, Fast Delivery
I installed this unit about 36 hours ago, so things could still swirl down the tubes, but there is a lot of reason for optimism.

We've had the Kenmore Elite version of the LG refrigerator for almost six years now.  Within the past two, the ice maker began giving us problems.  The major problem was it would often not stop making ice when the bin was full.  The result was the ice would pile up on top of the ice maker, eventually physically stopping it from dumping the cubes. Eventually, the water outlet would also freeze, which meant getting rid of some ice and getting out the wife's hair dryer.  The problem was the arm that is supposed to signal the bin is full. This unit has a different design for that arm that solves the problem.

The original unit stored the arm in the up position and would attempt to drop it to detect when the ice bin is full.  Ours would get trapped under the newly dumped ice, which for whatever reason did not put the brakes on the ice making process.  The new design starts with the arm in the down position, tucked under the ice maker.  It attempts to raise the arm when it is ready to dump and refill.  If it can not, the process stops until the ice level gets low enough to allow the arm to swing up.  The arm returns to the down position before the cubes get dumped, so there is no chance the arm can get trapped in the up position.  Problem solved!

The housing around the water outlet also has changed.  This is smaller and looks better protected.

Installation is easy: two mounting screws, a plug for the wires and a grounding wire that gets screwed into the ice maker.

Ice makers have always been problematic. I expect 5-7 years before I have to replace them. At least from the design change, I don't think I'll be replacing this one for the same reason as its predecessor.

The vendor, Quickshipparts, got the unit to us in three days, which is very quick.
