Product review (5 stars): Almost perfect replacement
Purchase this kit to replace the original unit in a Samsung refrigerator.  Mine was not working right since day 1.  It never knows how to stop making ice once it's full, and got stuck every 3 days or so.  After a few attempt to dislodge the frozen icebucket, the unit went caput, and only made the dreaded knocking noise.  I purchased a replacement kit on eBay, but did not replace the icemaker logic board.  In retrospect, I should have, but not sure if it would have made a difference.  Samsung knows about this issue, but did not  comment on it other than recommend replacement of the icemaker.  It is now known that this is an issue with most Samsung refrigerator icemaker, and that logic board made before 2005 has this issue.  You have to change both the logic board and the icemaker.  I changed mine, and it works within 24 hours.  I was worried, because after replug in the  power, I did not hear the water filling the icemaker.  It has been close to a month, and so far so good.
Update: the icemaker housing was a little off from the original icemaker.  The little hole on top of the icemaker to receive water filling was not alligned to the water filling nozzle.  This was because the sliding tab was off, and even with me pushing it in hard, the front locking tab did not quite make the engagement.  This resulted in water spilling out from the icemaker, and froze the auger mechanism and well as the ice bucket.  It took me 2 days to unfreeze it after unplugging.  Once I yanked on the ice bucket and pulled it out, I was able to figure out the problem.  So far so good.  It's been a day since I pushed in the icemaking housing.  Will update again if it is still malfunctioning. I am happy to have ice about a year out (tired of lugging back icecube to store in my refrigerator - which is ludicrous, now that I snapped out of it).
