50. ur distinct functional systems e Refrigeration system e Water system e Harvesting system e Electrical control system These four systems work together to accomplish the production and harvesting of ice A problem in any one of these systems will result in improper operation of the entire ice production cycle When troubleshooting the icemaker it is important to analyze the entire system operation to determine which system is not functioning properly then pinpoint the component within that system that is malfunctioning Determine what corrective action must be taken before making any adjustments or replacing any components The icemaking process The Follett icemaker uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle Water is supplied to the evaporator from the water reservoir where the water level is controlled by a float valve This valve also shuts off the water supply when the icemaker is not running When the icemaker is running a layer of ice forms on the interior surface of the evaporator This ice is continuously removed by a slowly rotating 12 RPM auger The auger carries the ice upward into the cavity formed by the top bearing housing and the compression loop where it is compressed to remove excess water When the ice reaches the desired hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and into the ice transport tube The discharg
