What happens & when:

Error Code (if any):
Parts or tests already tried: I replaced the ice maker completely but it still will not make ice. The aquasense receiver is blinking. Should I try to replace the boards there?

This could be a board issue, I am enclosing the tech sheet that has several test to help determine the problem.

Ok, thank you for the sheet! Another question I have is would the ice maker fill and create any ice at all if those sensors are faulty?

Not likely, but I would recommend the tech sheet testing.
