Product review (5 stars): Good part and supplier
It fixed my issue of no ice.  This seems to be a weak part for the Samsung refrigerators.  Before you purchase one try the forced defrost feature.  You can find directions on youtube.  It may or may not fix the problem but it is worth a try.  I did it even for the new ice maker as it was slow to make ice.  It takes about 30 minutes to complete and the refrigerator beeps as this is going on.  It didn't defrost the food in the freezer and your food is fine in the refrigerator.  I read where the water feed line can freeze.
