Ice maker not making ice. No water getting to the ice maker. Checked water source - ok, checked supply line - not plugged or frozen.

I disasembled the solenoid valve but couldn't tell anything from that. Reassembled solenoid and reinstalled. Still no water to the icemaker. I don't know if it is the actual solenoid or some other electonics not communicating with the solenoid. I noticed that there is a red light at the infared sensor on the upper right side of the freezer door that flashes a series of two quick flashes. Not sure if that means anything. Anyone got any ideas?
