4. THERMISTOR
A thermistor (semiconductor) is used as a harvest control sensor and anti-slush sensor.
The resistance varies depending on the suction line temperatures.
During the harvest cycle, the thermistor detects the evaporator outlet temperature
and starts the harvest completion delay timer (Setting 1: 0 to 210 seconds) when the
temperature reaches the harvest completion temperature (Setting 16: 6 to 12°C).
During the freeze cycle, the thermistor detects the evaporator outlet temperature and
momentarily stops the pump motor to prevent slushing in accordance with the anti-slush
control (Setting 12: 0 to 2) and the slush ice control (Setting 62: -5 to 20°C).
No adjustment is required. If necessary, check for resistance between thermistor leads,
and visually check the thermistor mounting, located at the evaporator outlet.
