The board is not seeing the ice maker switch

From Tech Sheet W16577713, p.45:

1.Unplug the IM from the door harness while in the HOME position. Using your meter, test between the Yellow and Blue wire on the IM for continuity (IM switch should be closed).

2.Measure door lock assembly resistance across the PTC terminals. Expected: ~200 ohms cold, rising sharply once energized.

3.Inspect strike and latch alignment. A warped door or misaligned strike prevents the switch stack from closing in the correct sequence.
