Product review (5 stars): Whirlpool Refrigerator Ice maker Kit
Item was 100% complete and new.  I concluded the problem with original was the ice maker from the LED action on the refrigerator wall at the sensor.  I viewed a couple of YouTube tutorials on removal and installation (easy to find them although not all of this unit but applied in general).  Be sure the cable harness connector on left inside rear of the ice maker is secured.  During installation, be sure to insert the connector from refrigerator wall through the opening into the unit or it won't allow the unit to seat in position.  Will be obvious when you do the job. Very pleased.  Making ice again.
