Okay guys, I'm back at square one again. I replaced the ice maker as well and that did not fix the problem. The tray pretty immediately filled with water and made an initial batch of ice, however the ice sat there for ~10 hours while the fingers were at about 2:00 without doing anything further. I still get the two blinks followed by a one second pause. I put the old infrared boards back in to test them with the new ice maker and still no dice. I then went back to old faithful and jumpered the black and black/white on the receiver side and immediately the ice making cycle began with the new ice maker. As best I can tell the ice maker and the infrared boards are what people replace in these scenarios. What could be going on here? Did my old ice maker short out the new infrared board?
