I fixed the ice maker today. Somehow, it was not filling and making ice. Before calling a professional, I thought I would at least try to troubleshoot. You know how it is when you're Googling along, and you get just enough of a hint to convince you that the answer is just another click away... then, next thing you know an hour has passed. Or more. That was how it was this afternoon.
Finally, I found the service manual here and here. Unfortunately, this is a PDF that cannot be published on Google Documents (yet). Look for Whirlpool manual R-92, JOB AID Part No. 4322658A. The part number for the ice maker is actually 4322658A, for both Whirlpool and KitchenAid models. The manual's foreword, p. ii:
This Job Aid, “Whirlpool & KitchenAid In-Door Ice System,” (Part No. 4322658A), provides the technician with information on the operation and service of the Whirlpool & KitchenAid In-Door Ice System. It is to be used as a training Job Aid and Service Manual. For specific information on the model being serviced, refer to the “Use and Care Guide,” or “Tech Sheet” provided with the Refrigerator/Freezer.
If all else fails, I cut and pasted the two sections that I used from the manual into a Word file.
Various components of the ice maker can be found fairly easily online at sites like this one. Model number of our fridge is KitchenAid KSCS23INSS00. Curiously, Whirlpool is the origin of the KitchenAid fridge. I wonder if one manufacturer makes the parts that are used in different brands? Probably.
In all of my browsing to try to find the answer to the problem, something that is inordinately time-consuming and frustrating, I realized that I could very easily have used my cynical go-to plan: if all else fails, hit it with a hammer. But, that would only make me feel better for just a little while.
None of this will make sense unless you actually unplug the fridge from the wall, take the ice maker out of the freezer, and remove the cover first.
Don't force any part of the ice maker, no matter how tempting it would be. Not to worry. If, like me, you pass the optical test and the electrical bypass with the jumper wire on the T & H little holes in the side test, and then you power off, power back on, open the door, and pass the LED blink test, you will be rewarded with the specific results you are hoping for. The electronics of the ice maker will cycle a few times and will set the ejector into the "home" position with the blades at 2:00. Now, I am waiting to be sure the thing is cycling properly on its own.
