Noisy gear on whirlpool ice maker when the plastic wheel turns against the teeth

SOURCE: ice maker stopped making ice. water works fine

chande the filter

SOURCE: ice machine isn't working

Two things come to mind.

First, the water valve at the bottom rear of the refrigerator may have failed. You didn't mention if there is a water dispenser and whether or not this is still working. This valve pumps water to the icemaker and water dispenser when the control unit of the icemaker calls for water. Also, there could be a blockage in the line which brings the water to the icemaker.

The other possibility is that the part of the icemaker controls which calls for water from the valve has failed. If this has happened, it would likely be more cost effective to replace the icemaker unit.

Testimonial: "Thanks for the advice! I have a service person coming out on Thursday to take a closer look at the ice maker."

I have the same model. This has happened to me several times (usually when the door was kept ajar without notice).
Simply open the door, take a common hairdryer and blow at high speed (hottest also) all around the area of where you can feel the ice in the tray, but hasn't dumped yet. It will usually take about 5-8 minutes of consistently moving back and forth around that area. What has happened is the lines bringing water to the trays have frozen over. When you "thaw" them out, the ice made will dump in about 45 minutes. When you hear the ice fall, you will know it's in working order again. I have NOT heard this is a "flawed" icemaker, only that it is hypersensitive to freezing lines when a door is left ajar. In your case, to prevent this from happening again. If you shut the icemaker off again, make SURE you turn off the source of the water feed BEFORE you turn off the ice maker. By doing this, the lines will empty as it makes it's last tray of water. Try that - very confident it will fix your problem!
