Low Temperature Safety Thermostat
The low temperature safety thermostat protects the ice
machine evaporator from damage caused by freeze ups.
Freeze ups are usually caused by a buildup of scale on the
surface of the evaporator. Additional causes would be any
problems that result in the motor, gear motor or auger
slowing down.
NOTE: The low temperature thermostat is not used on all
versions of CNF0201/CNF0202 model ice machines.
1. Allow the evaporator to thaw.
2. Throughly descale the evaporator. Refer to “Heavily
Scaled Procedure” on page 32.
3. While the evaporator is soaking test the operation
of the low temperature thermostat. Refer to “Low
Temperature Thermostat” on page 89 for test
procedures.
4. Perform a “Detailed Descaling/Sanitizing Procedure”
on page 34 and test run the ice machine.
