Hello and thank you for the opportunity to help you.
If you look at the icemaker, where are the white fingers pointing. Using the ice mold tray as a reference, are they pointing slightly above this or are the white fingers down in the ice mold itself?
I can squeeze it pretty easy
One flash every second means the ice maker is in harvest mode or the optics are faulty. Have your ice maker fingers stayed in the same position or are they down now?
Ok. I'm going to suggest you replace your optics boards. They come together. Very easy to install. I asked you to unplug your refrigerator because this will sometimes "reboot" the control boards. The red LED was a red flag. Pardon the pun. It should have been solid green. The other tasks I've asked of you seem normal. I hope this information helps.
