Product review (5 stars): Super easy.
Works great in my LG LRSC26925SW side by side.  If I knew it was that easy I would have replaced my half functioning ice make a year ago.  Mine would simply stop dispensing ice, power cycling it would do nothing and if you hit the test button underneath on the right side it would beep but the tray wouldn't respond.  If found that banging on the bottom of motor on the right side after you activated the test mode would force it to cycle.  It would work fine for a few days and stop again.

I replaced this thing in all of 5 minutes.  You simply take out one screw holding it to the roof and it slides out enough to reach a wiring harness on the left side.  I uses a small screw driver to wiggle the safety clip to get the connector apart.  Take the new one, plug it in, slide it in the mount and replace the screw.  That is all there is to it.  Also, the older model ice maker that was in mine had a problem with the tray splashing water when filled and creating an ice sheet on the back wall and top of the freezer light cover.  This model includes the redesigned deeper tray that prevents the splashing problem.
