Manitowoc series 400 not making ice water is running what is the problem

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.

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.

Try cleaning the radiator for the ice box compressor it could be tripping it's thermal overload switch, if that doesn't work check to see if the termostat setting is in the range for the compressor to turn on when the ice starts melting.

compressor or condenser fan motor bad, very rear problem, or check wires on physical damage.
