I took apart the ice maker before looking for a replacement on Amazon and then I saw this control board mentioned.
Before, the ice maker indicator light would flash twice then pause for a second even when the door flapper was closed. That is the indication that the infrared sensors aren't working since having the flapper closed should result in a solid red light to indicate connection made.
To fix, I only had to replace the smaller side under the flapper. I saved the larger side in case I need to replace that one later.
After a summer of no ice and a couple of attempts at fixing it, my wife and I are so happy that I figured it out... and don't have an ice maker sitting on the counter ;)
