Product review (5 stars): easy DIY job
My Samsung refrigerator (RF4287HARS) stopped dispensing ice, but water was still working fine. When i tried to get ice, i would just get water.

A quick google search pointed me to the possibility that a broken piece of plastic on the top of the ice dispenser paddle could be the cause.  I did not see any plastic fall out when the ice dispenser stopped working, but i noticed that the ice paddle would keep going when pressed and then caused the water dispenser paddle to be pushed.  This matched the online videos and comments I had read from others.  So I took a gamble and ordered.  Shipping was super fast and after watching a video and reading other comments, it only took me about 20 minutes to replace the old unit.  There is an excellent step by step with photos provided by another reviewer. I would only add a few tips.

Watch a video on youtube by Joe Wier, he has a good tip on how to remove the dispenser assembly, for me that was the hardest part (but only took a few minutes).

After removing that unit from the rest of the refrigerator, I used a small pry tool to help separate the DA97-08519A from the rest of the assembly.  If you look at the new unit you will install, there are a couple of plastic tabs at the end of the long u shaped arms that slide into the rest of the assembly.  using the pry tool helped me be sure those tabs were clear  so i could remove the old unit.

note that the wires from the unit tuck under a tab before they connect to the rest of the display.  Be sure new wires are tucked under before you fully attach the dispenser back to the display. I didn't do this the first time and it caused the whole assembly to want to go back into the display.

All in all, a easy project and a chance to save a bunch of money over having a repair man come out for this job
