Ice maker stopped making ice. Replaced the solenoid, which didn't work, but in the process remedied a low water flow problem by replacing the saddle-type supply valve. Still no ice.

This has the "optical" sensor, and when the door is open, the status LED gives two flashes, a longer pause, two flashes, etc. When I press in the paddle switch on the left side, the LED is on steadily.

The fill tube at the top is not itself frozen, but I can't tell if there is freezing above it.

Any thoughts?

I will have to pull the refrigerator out to get access to it, but I can do that. Do I assume that is the test to see if there is freezing somewhere in the line?

Thanks, very much. I won't be able to try that for a couple of hours, but I will give it a shot and let you know what the result is.

I did what you suggested, and it seemed that, although it was difficult, some air did move through the tube. (I tried the other line first, which is slightly larger diameter, and no air moved through it, so I assume that was the line for the water dispenser.

Any further thoughts?
