Electrical control system operation
The wiring diagrams that follow illustrate the circuitry of these Follett ice machines used with ice dispensers. Both
normal operation of the ice machine (Stages 1–6) and non-normal diagnostic sequences showing torque-out
(Stages 7–10) for use in troubleshooting ice machine problems are shown.
Circuitry notes
When the ice machine is used with a dispenser it receives power from the main power supply. Disconnect the
power source before performing service. When performing electrical service, always use a meter to determine
whether or not the components being serviced are energized.
§ High pressure cutout opens at 425 PSIG (2930.3 kPA) and closes at 287 PSIG (1978.8 kPA)(auto reset).
§ The bin signal input to the control board in the 414A ice machine must only be initiated by contact closure. Do not
supply power. To run the ice machine in the workshop, use the bin signal jumper (P/N 01069095).
