The opto coupler was the next potential issue I was going to look at after ruling out the micro switch. I guess at this point it makes sense to rule out the opto coupler. Looks like a simple repair, unsolder and resolder three pins.
Any chance if you know if there is a certain polarity to the opto coupler pins? I want to avoid installing it incorrectly.
