Product review (5 stars): Not the Greatest Ice Dispenser but an Easy Fix!
Our refrigerator is about 5 years old and the ice maker was jamming and turning out full cubes even in the crush setting.  On closer inspection of the auger area of the ice bucket, we discovered that the plastic pieces of the assembly were cracked and broken in a number of places.  This allowed full ice cubes to wedge behind the chopping blades and not only jammed the ice dispenser but also bent the blades so that ice was no longer being chopped.  I ordered a new ice maker assembly (for about 20% of a service call) and the dispenser now crushes and delivers ice like new.  While I'm not particularly pleased with the durability of this icemaker, the replacement part was affordable and slips into place with no tools or extra work.

If your icemaker is having issues dispensing, check the plastic around the screws and if it is cracked or broken, this may fix the problem!
