Electrical system
Normal control board operation
The PC board indicator lights provide all the information necessary to determine the machine’s status. Green
indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions;
Red indicators generally represent alarm conditions, some of which will lock the machine off.
A green light labeled POWER indicates power to the machine. A flashing green light labeled CPU is normal and
indicates that the Central Processing Unit “heart beat” is working. All other normal operation status indicators are
covered as follows:
1. Ice machine is making ice.
2. Ice machine is not making ice.
3. Ice machine is not making ice.
1. Normal running.
2. Normal time delay. When the bin fills with ice, the LOW BIN
light goes out and the refrigeration and auger drive systems
immediately shut down. The TIME DELAY light comes on,
initiating the time delay period. When the time delay expires,
the machine will restart provided that the LOW BIN light is on.
3. Normal purge indicator. After a selected period of ice
making time has elapsed (2 or 6 hours), the ice machine will
automatically self-flush. The refrigeration system will shut
down but the gear motor will continue to run. After the flush is
complete the machine will refill and start without a time delay.
