Open the freezer on your side-by-side refrigerator and remove any food items from the top shelf. It is not necessary to unplug your refrigerator from the wall.
Remove the top shelf above the ice maker. Lift up on the bottom of the ice maker bucket and pull it from the freezer to expose the auger motor assembly. Dump any ice from the ice maker bucket to avoid refreezing the partially melted ice around the auger arm inside the bucket.
Turn off the ice maker and remove the three 1/2-inch hex-head screws from the auger motor assembly with a 1/2-inch nut driver. Lift the motor up and tilt it forward slightly to begin pulling it from the freezer, exposing the wiring harness connection.
Squeeze the tabs on each side of the wiring harness with your fingers. Pull the auger motor wiring harness from the connection in the back freezer wall. Finish pulling the auger motor from the freezer and set it aside.
Loosen the two hex-head screws holding the original GE ice maker mounting bracket to the back wall of the freezer. Do not remove these screws completely.
Disconnect the ice maker wiring harness from the freezer wall. The harness is located beneath the ice maker and to the right.
Lift up on the ice maker to release the ice maker mounting bracket from the hex-head screws. Push in on the tabs holding the fill cup to the original ice maker to release the cup from the ice maker. Discard the original ice maker.
Snap the original fill cup into the slots on the back of the new GE WR30X10093 Ice Maker. Hang the mounting brackets attached to the new ice maker on the two hex-head screws in the back wall. Confirm the fill cup sits beneath the fill tube protruding from the back wall of the freezer.
Place a 6- to 10-inch torpedo level on the ice maker. Verify the ice maker is level and remains level as you tighten the hex-head screws to secure the new ice maker in the freezer. Snap the ice maker wiring harness in the connector on the back wall.
Insert the auger motor assembly into the freezer. Snap the motor’s wiring harness into the connector on the back wall.
Attach the motor with the hex-head screws you previously removed. Do not tighten the screws until you center the auger motor in the freezer. Snap the wiring harness cover onto the bottom of the auger motor assembly if it fell off when you originally removed the auger motor assembly.
Turn on the new ice maker. Install the ice maker bucket into the freezer. Make sure you line up the auger motor with the drive shaft on the back of the bucket. Install the top shelf above the ice maker bucket.
