its a Kenmore 106.52552100
Yep, Whirlpool made.
No water in ice maker tray. Fill tube is not frozen. Optics working according to diagnostic testing. I replaced entire ice maker (2198597). Still no water getting to ice maker. Could my inlet valve be bad?
For no ice or low ice production, always confirm normal (0-5 Deg F) freezer temperatures before beginning diagnostic checks. The ice maker is designed not to run if the freezer in not in this temperature range.
If your freezer is cold enough and you are sure the optics are working then I would go ahead and replace the water valve.
Optic TestingThe water dispenser works.
This only tells you that there is running water to the refrigerator.
The water in the door uses a different part of the valve then the ice maker.
Change the water valve and let us know how it goes.
