RFF2500 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
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.
