Watched video and saw how easy this repair was, so ordered the part for under $100. New part arrived in a few days. Install is really easy--unplug fridge's power, unplug ice maker's wire harness, remove three screws with 1/4 socket, pull out old unit. Re-use wire harness, metal level arm, and cover. Install new unit following steps in reverse. EASY!!!
Had entire job done in well under 30 minutes! Saved a bundle doing it on my own, and the problem is solved--we now have ice cubes only--no leaks!
