Product review (5 stars): Well That Was Easy!
My ice maker stopped working, so I watched a bunch of extremely helpful YouTube videos to figure out what was broken (it is almost always either this unit, or the water valve, or the ice-level optical sensor), determined it was this unit, got a new one from Amazon delivered next-day no-extra-charge (Prime!)--and on a Sunday, no less! It took about 15 minutes to replace the old unit, and Viola! Ice again.
