Product review (5 stars): Great replacement, not sure that it is OEM, but it works so all is good
My old ice maker malfunctioned in some strange way that flooded my freezer with frozen water. Thankfully it was cold enough to freeze a blockage in the supply, so there weren't too many things encased in ice.  This installed very very easily, and started making ice within 14 hours (instructions said it could take up to 24).

I do not believe that this is an actual whirlpool part. Nothing, including the box, instructions, or icemaker itself, say whirlpool. This is strange for a company to not put its logo all over its ice maker or packaging. Also, it comes with four different types of adapters - why include multiple adapters if the product is an OEM replacement part? But who cares, it works, and I am back in the ice business.

I ended up not needing any of the adapters (wiring harnesses) as the existing harness fit perfectly in this ice maker.  Pro-tip: to disconnect the original harness from the original ice maker, you need to FIRST remove the white endcap from your icemaker (the square white part that the on/off arm is attached to). You will then see a little square hole with a little piece of white plastic in it on the side where the harness plugs into the icemaker.  Push this down while pulling out the harness, and the harness will pop right off.  Just start tugging before you push in this pin (Like I did at first) will just end up with one or more wires popping out (which is also why you need to unplug or flip a breaker if you cant access the plug easily). Just start jamming a screwdriver into the harness hoping you will snag whatever is keeping it secure and you will just end up being angry or, even worse, breaking the original harness)>

Another pro-tip: There is a semicircle "punch out" on the back of this where the inlet chute will sit (possibly not applicable to all models).  Break this out (a knife helps) BEFORE you install everything.  Otherwise, you will have to uninstall and reinstall.
