The lining of the ice mold (Whirlpool) started flecking off (black flecks in the ice cubes), so I decided to replace the mold.
Loosen the two 1/4 inch upper nuts and remove the lower nut to remove the ice maker from the freezer. The hardest part was getting it unplugged. I used a small blade screwdriver to release the catch on the connector and pull it out.
Remove the ice maker front cover. If you have a skinny enough phillips screw driver, there are two deep set screws through two holes on the lower portion of the control module (otherwise, remove the three screws on the controller, unlatch the shut-off arm from the control module, and separate the controller to access the mold screws). Unhook the shut-off wire from the end of the tray. Unscrew the two screws holding the mold and remove the mold.
Remove the plastic hardware from the old mold and install on the new mold.
Attach the new mold on to the control module.
WARNING WARNING WARNING!!! The mold I bought already had the alumilastic on it for the contact point to the thermostat. When I installed it and tightened the screws, the alumilastic was dried out, didn't squash down, and dented the bi-metal thermostat on the controller, ruining it. I had to buy a new thermostat. Be sure to check that the alumilastic is pliable. If not, take it off and buy some fresh to put on there.
Re-install the ice maker. It took a while to get the first batch of ice because the ice maker was at room temperature and I had the freezer door open for several minutes. So the freezer had to get cold and the ice maker had to chill down. Once everything got cold, it started making ice again.
