I have a Scotsman ice machine that I've been working on. It has the Auto IQ Controller with no fault codes. Only issue is the bin full indicator light is staying lit when the machine is not even producing ice at the moment. The machine won't even run. If I turn it off and power it back on it will attempt the harvest cycle for about 1-2 minutes and shuts down. I cleaned the bin sensors with ice machine cleaner and the bin full light is still lit. Is there a way to test the sensors or how exactly do you check them? I know they are supposed to be replaced together. Thanks for any help.
