Hi Gene-

It sounds like you are the Ice Maker King!

Model: KSRG25FKSS03

Symptoms: Ice Maker does not fill with water.

I have verified that the water line is NOT frozen and not blocked. If I switch the ice maker and water connections, water will come out at ice maker fill tube when the "chilled water" flap is pushed.

LED results:
If door is open: Blinks 2 times then off and repeats.
If door is open with left side flap closed: Constant on/red
If door is open with door shut trigger closed: No light

Thanks
