Light was blinking on the Electronic Control Boards. Ordered replacement (emitter and receiver)and installed, and now it's working.
Some note: 1 year ago, the board started to blinks (meaning it's bad) but it was still making ice. This gave me a false error when it really failed, took the risk and ordered the replacement parts and all is well now.
One more thing to pay attention to , and it may only be on my model of refrigerator, but the wires harness that connect to the receiver board (big board) have large and stiff wire. With limited space where the board and the wire are seat at, it put lots of pressure on the pressure on the board's connector. This pressure, over time, will cause the right angle connector's solders to crack and may be a contributor to the failure. If you're installing the new board, try to re-inforce the connector with some rubber heat glue and also relieve pressure from the connector's end, which I hope will prolong your board.
