Product review (5 stars): Easy repair
Bought it elsewhere but reviews on Amazon helped me so here is my 2 cents.

My ice maker stopped working very suddenly.  I noticed it was making some strange sounds - I'd call it a whooshing sound.  I was annoyed but then again I'm used to annoying sounds coming from this fridge's ice maker!  A few days later I ran out of ice!  Based on my research the 2 main culprits are either the ice maker itself or the valve that sends water to the ice maker.  I busted out a hair dryer and thawed out the ice maker for a few minutes and put the tray back in and a few seconds later 9 cubes dropped.  I took this to mean that the valve was good and the maker needed replacing.

The installation took literally 2 minutes.  There are youtube videos that show you how to do it.  If you have opposable thumbs you can do this repair! :)  Once I got the old ice maker out I could see (barely) that there were cubes in there.  Don't forget to hold down the reset button once you get the new unit in there.  I tried pressing that button on my old unit but I was either not doing it right or it was very dead because the old one never chimed when I held down the button.  The new one chimed after a few seconds once.  Then a few minutes later it chimed again which was what I was hoping to hear.

Suggestions:
1) If your ice maker stopped working take it out!  There is 1 screw and a plug to deal with, that's it.  If you pull it out and look inside with a flashlight do you see ice?  If so then you know you are getting water so if you are like me you are going to order a new ice maker and move on with your life.
2) Don't buy Samsung appliances.  This is the 2nd repair on the fridge.  The first was under warranty where ice builds up on bottom of freezer.  It's a manufacturer defect for sure.  The fix for that was easy too but still.  My Samsung dryer also had to be repaired under warranty.  Never again.

My model: RF4287HARS
My ice maker model was actually DA97-07365A but this worked perfectly.  It seems the A and G are interchangeable.
