Very unusual for one of these to not stop. There is a magnetic proximity switch located on the bottom right side of the water curtain that serves to both cancel a harvest/drop and to shut the unit down on a full bin. When a drop occurs the control board sees a open and then close of the switch and restarts a freeze mode. If the ice drops and the bin is full the curtain is blocked by the ice behind it from closing again and the unit shuts down on a full bin indication. If the curtain does not open and close after 3 hours it would lock the unit out. Therefore I assume that the switch and the board are working. Most likely you either have the unit on a non-Manitowoc bin or are missing a deflector plate in the Manitowoc bin and the ice is falling out of a service door.

First, this us a very old system and probably needs to be replaced if it really is an R12 system. The unit is probably at least 40 years or more old since they stopped producing R12 about 1970's. If your manitowac ice machine is usable still, it probably has lost its charge and will need to be refilled with a suitable refrigerant. I actually still have a jug of R12, but I generally charge systems with the only substitute still available R420 if you can find someone who still sells it. I saw that both refrigerant were being phased out and purchased a couple of jugs and only have a little left. My suggestion if you want this ice machine in operation again take it to an ice machine repairman and have him repair it. Good luck.
