2 pulses on my Whirlpool Ice Maker

Optics are blocked or defective; infrared beam path between emitter and receiver is obstructed or the optics boards have failed.

First step

Clear the optics path (clean dirt/frost from lenses, check ice bin alignment, check ice level below notched openings), then repeat the optics diagnostics procedure. Replace both emitter and receiver boards if necessary.
