RF1200R/RFS1200R Troubleshooting

HEAD SECTION FOR RACK REFRIGERATION SYSTEMS

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. Ice Chute Safety Switch
C. 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 and suction solenoid valves energize.
The ice machine will continue to make ice until ice
contacts the bin thermostat and the liquid line and
suction solenoid valves close.
The ice machine remains off until ice no longer contacts
the bin thermostat.
