you can check the infrared optics with your cell phone camera -they will light up on the camera screen.

coin in and coin out optics are different, they can't be swapped,  in a pinch,  i have soldered in extra senders/emitters to a coin drop optic to make it work for coin in.

with older sigmas check connections at the board and the optics/comparitor, usually one is dirty or a pin has pulled out, maybe a broken wire from door being opened a zillion times in its life,  -pull on each wire around hinge, one at a time -you may find a stretchy one.

I've replaced both coin optic with known good ones. I'll check the pins on the door board. If I had to guess there's a problem with a hopper board, but I'm not sure if it has one or if it does what one is it ??

If it's jammed, force it... If it breaks it needed to be replaced anyway...
