I did troubleshooting, such as verifying a water line was in place to the ice maker. There was water in the door that worked fine. Also replaced the water filter, and tried adjusting the wire arm (bale), but nothing worked.
So I found your ice maker replacement video on YouTube, ordered part # W10190965, and followed directions to remove the old and install the new part.
There was partial, immediate success: water flowed into the ice cube tray and froze.
I had trouble with the bale staying in the up position, which caused some ice dams to form, and water to overflow a couple of times, and so did additional research online.
I tried adjusting the water flow, but taking off the front, white cover, and turning the plastic screw a half turn clockwise. This helped the ice dams, but did not automate ice making.
The real problem was that I had to re-use the old bale - the wire arm that tells the freezer when to stop producing ice - and it was too tight. The plastic receptacle in the back of the ice maker was also different, which contributed to the tight fit.
So I had to manually lower the bale every time ice was ready, or it wouldn't flip out and refill the tray with water.
I read online that you could pull the bale out of the back slot, and keep the front in.
This worked great!! The ice maker is totally automatic now.
One word of caution - don't remove the bale from the front portion, as that's the timer mechanism that tells the ice maker when cubes are frozen and ready to flip.
As a 50-something woman who is pretty handy, this was still a challenge to troubleshoot.
Removing the old icemaker and installing the new one was actually the easy part!
The videos were very helpful.
