Product review (4 stars): Cheaper and works great!
OK, I have a GE side by side refrigerator that had an ice maker that worked "some times".  I have had the fridge for about 12 years.  I found this replacement ice maker listed all over the internet.  The highest price was 144.  There were two outfits here on Amazon selling the unit.  One for 74 dollars and this one for less.  I figured they were the same so let's save a few bucks.

Look at Youtube about ice maker replacements.  There are a few videos on there concerning this subject.  The videos I saw showed the ice maker along the back of the freezer.  Mine is located along the left side of the freezer.  It was a little more difficult to see the screws, but not all that difficult.  I turned off the power to the fridge, removed the ice try and the removed the screws (there were 3) holding the old ice maker in place.  I lifted the unit, carefully, and held it with one hand while disconnecting the power cable with the other.
The instructions give you different options for different configurations.  For my unit they wanted me to do a couple of different things.  Remove this part from the old and put it on the new one, so on and so forth.  The parts were NOT interchangeable.  Guess what?  I put the new unit in as it was.  The only difference was there was no bottom screw attachment.  So this unit attached using only 2 screws.

When I got up the next morning I checked the ice maker.  I saw ice.  The unit works just fine.

I would have given this 5 stars, but the instructions can be a little confusing.  It is not this companies fault.  I realize the manufacture has to contend with many different models.
