Product review (3 stars): Works okay - but its a substitute part
When my 2010 Kenmore Fridge died, I figured out that the motor had failed and wanted to replace. Being an IT geek, I tend to research stuff and learned that the W10188389 is actually a replacement part for other older and less expensive parts.  But I thought I'd splurge and just get the part specified by Sears/Kenmore.

When I received the part, it didn't match the picture (grey instead of black) and also was not an exact match for the original part.  I couldn't find a part number on the motor either.  It was thinner and had small fins on the back section which gets inset into the rubber grommet.  Layout of connector pins is slightly different too. Looked just like the parts listing for $15 to $20 less.  But it still fit even though loosely, so I hooked it up and it seems to work.  The loose fit doesn't seem to be a problem even though the body of the motor can rotate in the bracket and it runs quietly.

I'm giving this two stars because it works, but I wouldn't buy anything else from this vendor

Update: After talking with the vendor, we both agreed that it was a perfectly good, substitute part and the vendor credited the cost difference.  So I've added a star because the vendor was willing to work with me.
