Product review (3 stars): A very strange thing indeed
I ordered the nylon drive cam for this unit, but while going through remove/replace procedure I noticed that a metal shaft was sticking out of the front wall of the icemaker, which is not supposed to be.  Apparently something happened to cause the drive rod to come loose from its bushing which then caused it to gradually drill itself through the front wall.  The icemaker has never ever worked very well, so hopefully a new unit will improve this.
