Product review (5 stars): Whirlpool D7824706Q Ice Maker for Refrigerator
Great product at an awesome price!  Easy installation with our current wiring harness and bracket re-used.  Works like a champ!  Make sure you prime your water line to the ice maker by reversing your wires and pushing the chill water button until water comes up to the ice maker or you will wait a few cycles before the water finally reaches it.

We've been without an ice maker for years because of the replcement cost, this was a very reasonably priced OEM replacement!

UPDATE 03/17/2012  This unit "Occasionally" locks up with a full tray of ice because it gets caught between cycles and tries to fill the tray after not successfully dumping the last tray completely.  This has happened twice since we bought it.  First time I removed it, thawed it, and put it back into commission, no problems for months.  Second time I simply unplugged the power to it, used my wife's hair dryer to thaw the ice, and replugged it in, again no problems for months.  The unit just gets confused sometimes when the tray doesn't completely empty and it re-fills it with water resulting in stuck ice cubes and a stuck ejecting mechanism.

Also, depending on your model, you may want to bend the ice level sensor bar just a little to keep from overflowing your ice tray.  I had to bend ours down about two inches, worked much better afterwards, and no ice falling out of the tray anymore. Be careful not to break any plastic parts when you do so.

Still for the price I will leave it at five stars.  The unit has made at LEAST 1000 trays of ice cubes since we purchased it, and for the price, that is pretty reliable.

Thanks!!!
