I replaced the Ice Maker with a new Ice Maker AP4345120 (WR30X10093) purchased from ApplianceParts Pros.com. It was very easy. I used a Phillips Screw Driver to remove the bad unit. Used a small flat screwdriver to pop the side locking tabs on the wiring interface. I had to use the old water fill spout as the one provided didn't match and the side guard was not included in the kit. The whole process took less than 5 minutes.
