THERMISTORS
Condenser Thermistor
The condenser thermistor senses the refrigeration system “high side” temperature. This is used in conjunc- tion with the control board to determine the length of the freeze and harvest cycles.
Thermistors generally fail due to moisture or physical damage.
Refrigeration Thermistor
The refrigeration thermistor monitors refrigerator temperature and determines refrigerator cycles. This ther- mistor can also affect ice production, since the refrigeration cycle will take precedence over the ice pro- duction to protect perishables. The thermistor is placed in a sealed stainless steel well tube to protect it from moisture and is located on the inside wall of the refrigerator.
Bin Level Thermistor
The ice machine
To view actual thermistor reading:
1.Press “WARMER” momentarily and the far left LED (1) will come on and the display will show refrigerator temperature.
2.Press “COLDER” and hold until the middle LED (2) comes on, the liquid line temperature will be displayed.
3.Keep holding “COLDER” down and the right LED (3) will come on, showing the ice bin thermistor temperature. If you continue pressing the “COLDER” button, the display will alternate between bin and liquid line temperature.
