SUMP WATER THERMISTOR (T1)& LIQUID LINE
THERMISTOR(T2)
Function
The sump water thermistor sensor immersed in water
to detect sump temperature.The value supplied to the
control board is
used to Initiates freeze cycle
The liquid line thermistor senses the refrigeration
system liquid line temperature. This is used in
conjunction with the control board to determine the
length of the freeze and harvest cycles
.
Specifications
The sump water thermostor :
R2.0°C ±0.5°C = 14.75Kohm ±1%
The liquid line thermistor:
R25°C±0.5°C = 10Kohm ±1%
Check Procedure
1. Make sure the thermistor sensors installation
correctly
2. Disconnect thermistor from control board and
measure resistance.
3. Measure temperature at the thermistor.
4. Compare measured resistance/
temperature.Creadings to resistance/temperature
relationship
Within 10% of the published resistance value-
Thermistor is good
