Troubleshooting
Diagnostic troubleshooting for the ice machine
involves following flowcharts that are dependent on
symptoms of the failed machine.
Follow the flowcharts for the failure symptom and
model you are working on.
NOTE: Refer to the sequence of operation to
determine where in the sequence the ice machine has
failed. An example would be an ice machine that
energizes the gear motor, but the compressor does
not energize. Following the electrical flowchart will
quickly and easily eliminate non issues.

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. Low Evaporator Temperature Thermostat
C. Low Water Level Switch
NOTE: Placing the toggle switch in the ON position
starts the gear motor and refrigeration system. The
float valve controls the water inlet valve and water
level. The freeze cycle ends when ice contacts the bin
thermostat. The ice machine will restart when ice no
longer contacts the bin thermostat.
