Sounds like a sticking relay. Call for service. The control system is very complex.

Greetings, when this occurs, please add some salt to the idea in order to stop the ice from sticking together as much. That's the temporary fix. For any other machine, I would think this was an oil issue. That's the parts that create the ice stop-up due to friction caused by a lack of oil. I'm guessing that every time you clean the machine, you decrease the friction between its parts due to the water/soap that you use, but then the oily soap residue gets used up, and the issue returns. Please test out my idea. Thank you.

I didn't think their smaller units had a curtain, but it is referring to the plastic shield that hangs in front of the ice making grid or evaporator. This must be closed for the unit to run and there is a magnetic reed switch located on the bottom right hand corner of the curtain to prove that it is closed. Actually the magnet is in the curtain and the reed switch is snapped into the side of the grid. Make sure the curtain is in place and the magnet has not broken off. If that is in tact look to see if the reed switch is in tight. IF YOU DO NOT HAVE A CURTAIN... some units had a small plastic flapper at the bottom of the grid that was activated whenever ice dropped. Same system though with a magnet and reed switch. The magnets on some of these curtains and flappers were just surface mounted with some kind of adhesive and others have it captured inside of a plastic pocket made into the curtain. So if you don't see a magnet look for a spot where it used to be. If you want to prove this is the problem just get a magnet and hold it up to that spot for about 10 seconds and see if the unit cycles on. You will then have to order a new curtain or flapper or attach a magnet to the broken spot somehow.

If it doesn't run at all open the front panel and peer inside of the control box. See if there are any indicator lights on the control board lit or blinking. Check the plastic water curtain on the machine and make sure that the magnet is in place on the bottom right. Will need more information as to what lights are lit. Printed on the board next to each light is its corresponding function or response.

You're bridge thickness is set to high, lower the bridge on the sensor located when you open the front door behind the water curtain on the top. If the sensor is scaled badly replace it.

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.

is it plugged into a new or older outlet,and is it plugged in by itself,with no other appliances effecting its power

Possible un defrost cycle

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.

Machine dirty If you need further help, I’m available over the phone at https://www.6ya.com/expert/jerry_8a145f1328fa119f

High Pressure warning. Usually overheating of compressor. Check that ventilation is not blocked.

Fan is not operating properly (if air-cooled model) or No cooling water (if water-cooled model) or coils dirty (overheating)

Sounds like the refrigerant leaked out.
