Product review (5 stars): cheap fix to get your ice maker working again.
A cheap replacement component that saved hundreds of dollars versus calling a repairman. If you need to test whether it's the laser or something else preventing you ice from being made, make a jumper out of coated copper wire, trim just the tips about a half inch, and bridge the third and fourth holes from the bottom. Do that with the power off. You could electrocute yourself if you are touching the metal when you insert into the holes.

If it makes ice with the jumper, all you need is this part and your Frigidaire is back in service. Though you might want to compare the circuit board to the photo.
