I ordered the OEM icemaker replacement from Appliance Parts Pros. The delivery only took 2 days which was very quick. The install was probably one of the easiest I have done. You unplug the refrigerator, take out the ice bin and tray, unplug the old icemaker, remove one screw with a 1/4 inch socket, remove the old icemaker and then install the new icemaker, put the screw back in, plug in the icemaker, Plug in the refrigerator, turn on the icemaker, it will fill with water for only 1 second, you have to wait until the unit cools down, mine took about 30 minutes, it then cycled and filled completely with water and is making ice like new. Very simple.
Something I did not know was that an icemaker has a heater built in. When the ice is ready to dispense the heater comes on and heats the cubes just long enough for them to loosen so the plastic fingers can then rotate and push out the ice. As a word of caution, do not put you hand under the icemaker when it is plugged in, if the heater is on it will burn you.
