Troubleshooting
QUIETQUBE REMOTE AIR-COOLED MODELS WITH
REMOTE CONDENSING UNIT
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
Placing the toggle switch in the ON position starts the
gear motor. After the rotation speed sensor verifies 10
minutes of correct rotation the time delay ends and the
liquid line solenoid valve opens.
• When the refrigerant pressure is high enough to close
the low-pressure control the contactor coil energizes
and the compressor starts.
• The refrigerant pressure will increase and close the
fan cycling pressure control and the condenser fan
motor starts.
The ice machine will continue to make ice until ice
contacts the bin thermostat and the liquid line solenoid
valve closes and the refrigeration system pumps down.
• The refrigerant pressure drops and the fan cycling
pressure control opens stopping the condenser fan
motor.
• When the refrigerant pressure is low enough to open
the low pressure control, the contactor coil is de-
energized and the compressor stops.
NOTE: The ice machine remains off until ice no longer
contacts the bin thermostat.
