Congratulations. Hope all goes well
Thanks all for the advice. Update, took the cleaned old bin sensors (not installed) and plugged them into the controller. Secured them facing each other on top of the machine. The machine started up and completed a cycle making ice and has continued to work. So as was suggested there must be an alignment problem with the new installed sensors or they were faulty. Now I will check the original control board to see if that was the original problem. Thanks again for the input.

You havent mentioned if you programmed the new control
Is it worth pulling the bin sensors out and positioning them toward each other while plugged in to see if they see each other? Has anyone tried this? Better yet I will try this with the old sensors since they are out and easy to check.
The first thing I did was pull out and clean the eyes with ice machine cleaner using a tooth brush. there was scale on them but they cleaned up good, no visable cracks. I thought at the time this would solve the problem, but new eyes and control board later still the same bin full light on. It is possible the new eyes were faulty. I will put the old eyes back in today and see if anything changes.
yes it is clocked to 0 per the model cme506 per instructions. Bin full light is on and it does the same as with the old eyes and controller.
Maybe the sensors you installed aren't matching properly. I would suggest you go back to all the original parts and simply wash the original sensors with a tooth brush and soap. Then reinstall them with the original controller. Best of luck.
Is the controller programmed for that machine?
No, the front panel is the only part off. I reinstalled both side panels after installing the new eyes, after that didnt work removed only the left panel to install the new controller.
Is the top off while your running the machine ?

It does exactly the same as before, unplug let reset plug in machine it starts up goes into freeze mode compressor runs for about a minute then shuts down. Bin full light is on continually.

Yes I did install the universal (blue) control unit. It is exactly like the original controller and part #. Both eye units are seated with the deflector in the correct place.

It's strange that you have not been able to resolve this issue. I came across this similar problem multiple times and thanks to the experts in this forum i was able to get things right either by washing the sensors or, in some cases, by replacing them.
Did you install the universal controller ?
Hi all newby here. I have been reading thru the forum and have not found a solution. I am working on a CM3 506AE with the so it seems common full bin light on. I cleaned the sensors as described with ice machine cleaner light still on. Replaced the eyes/sensors and still light on. Next replaced the control module and still light on. what are your thoughts? Thanks
