Product review (3 stars): OK, Doubtful this is OEM
This unit does fit my Kitchenaid (Whirlpool), but when comparing it to the original unit, I doubt this is an OEM product.

In short, if I needed to buy an ice maker again, I would either spend the big dollars to be sure to get an OEM unit or buy the cheaper units that do not claim to be OEM.

Here is a brief list of what's different between the original unit and this product...

Original: 3 watt motor.
This product: 1.5 watt motor. A less powerful motor may fail sooner.

Original: Teflon coated.
This product: Appears to be painted.

Original: Fins (heat sink)which helps it make ice faster.
This product: No fins, which does make it lighter and a little smaller

The original unit has a slightly larger heating element than this product.

It appears that all the parts are interchangeable. In my case, the original unit's heating element burned out. So I replaced it with this product's heating element without any problems.
