Product review (5 stars): Watch a video first before attempting repair
Earlier this week, a large piece of plastic fell into my wife's tumbler as she was getting ice cubes, and I discovered the part was the front of the auger blade that had fallen off. With the part missing, ice cubes were dropping at the rate of only a couple every minute.

I was pleased to see that I could get the auger from Amazon Prime without having to but the entire ice maker assembly.  Thanks, GE.

As others have mentioned, there were no instructions included.  So I searched on YouTube using the product number and several videos were available.  I picked the first one on the list, by AppliancePartsPros which was 10 minutes long.  The front of the ice maker didn't match the one in our refrigerator, but the insides were the same, so the video was very helpful.  Watched it all the way through, and then it took me about 1/2 hour to replace the auger.  I would not have wanted to attempt the repair without viewing the video first.

Afterwards, both my wife and I were both amazed at how well the ice maker was working again.
