Product review (5 stars): Great motor, great service
I ordered this motor on Thursday, and with expedited shipping it was on my front door by Friday evening.  The best part was that even with this custom, first rate, speedy delivery, it was still less than what my nearby part store was selling it for.  To be fair, I would have paid the extra to buy it locally if for no other reason than to avoid having refrigerator parts lying around the kitchen for an extra 24 hours, but hey, I'm not complaining.

For those considering replacing this part yourselves, it is really quite easy.  If your refrigerator is like mine, you need to slide out the tray on the outside of the water/ice dispenser, revealing two screws holding the control panel in place.  This slides upwards and out, revealing the inner parts of the water dispenser and electrical to the motor.  Take pictures if you need to as you remove 6 or 8 more screws, nothing complicated, to get to the motor.  Also, on the inside (cold side) of the door panel, you will need to remove the socket the engages the bottom of the ice bucket.  This comes out as two screws, and engagement interface and a spring (don't worry, it's not one of those that is impossible to get back together).

The motor is driven by the two heavier wires, and I guess you could test the unit with an ohm meter.  Mine went to 0 when I checked these two prongs, but I (oops) never checked the new motor before I installed it, so I don't know what a normal reading would be.  The symptom of mine was the ice drop flap open and closed when I pressed the ice paddle, but the motor never turned.

Anyway, the new motor is great, my wife is happy, we have crushed ice again, and the old motor is in the recycle bin.  Good luck.
