Troubleshooting
SELF-CONTAINED AIR-COOLED
Normal Operation
When the toggle switch is placed in the ON position the
following controls must be in the closed position before
the ice machine will start:
A. Bin Thermostat
B. High Pressure Cut-out Switch
C. Ice Chute Safety Switch
D. Low Pressure Switch
E. Low Water Level Switch
NOTE: Placing the toggle switch in the ON position starts
the gear motor. After 8 minutes of correct rotation the
time delay ends and the compressor starts. The ice
machine will continue to make ice until ice contacts the bin
thermostat. The ice machine remains off until ice no longer
contacts the bin thermostat.
