After researching a number of sites for a diagnosis I tended to think the culprit was going to be the ice maker thermostat. Checking pricing and availability of the thermostat prices were very close at $40 BUT wait now you have to but the thermo mastic at another $35-$40. And after some continued research the factory ice maker in a $3000 msrp 4 door refrigerator was/is known to be defective long after warranty period expires. So it only made intelligent sense to buy the entire icemaker at a cost of $115 with tax and shipping plus only took 3 days with the holiday (Christmas) on a Saturday fed ex delivered it on Sunday morning with standard shipping. Most sites were questioning water valve but I had water from the dispenser with great pressure so I figured at most I'd have the worst done and a simple $75-$80 part to put on after. Now I'm not overly mechanically inclined, I can change my own oil in my car and change out an outlet or switch but it took an hour and a half between removing wiring and installing the unit and watching a youtube video from AppliancePartsPros.com. After plugging connectors together I heard unit attempt to cycle but no water in it. A bit frustrated I figured I'd check for plug the next, but low and behold about 12 hours later I heard the worst crash, whole ice cube tray emptying in the empty ice bin. Working like a charm since, actually best it's worked since we got fridge. Unit always had issues sometime a whole solid piece of ice or quarter pieces moons, now it's all uniform.
