Product review (5 stars): Take a close look at your icemaker!  The OEM drum seems to be a common weak link in the icemaker chain. This is more robust!
An elderly friend complained that his icemaker wasn't working. He had paid a repairman $200 for a housecall that determined a part was needed and that the $200 could be used toward the actual repair once the part came in.  After taking a look at the icemaker bin and the parts I thought, what the heck, I'll give this a try.  After disassembling the bin (6 screws) and taking the actuator rod and spring off (1-screw) and removing the 2 screws in the bin, the auger/grinder easily came out. It was clear that the drum was broken (the vanes had broken from the center) but what wasn't clear was that the drum was a separate piece from the auger. It appeared to be one piece and I was convinced I was looking for a one-piece auger/drum.  I thought this separate drum was not the correct part. I went on Youtube and found a repair video (very helpful!!) for this particular piece only then clearly saw that there was a cir-clip, washer, and nylon nut that held every together and that the drum comes off separately from the auger shaft.  I didn't actually take the old drum center off until the replacement came in but rather put it all back together so I wouldn't lose anything. Once the part came in it took about 15 minutes to replace since I'd done it all before. The auger didn't turn/spin as easily as I thought it should (it feels just a bit too snug), but it dispenses cubes and crushed ice just fine. And as a previous reviewer stated, this part seems much more robust that the one it replaces.
