LIQUID LINE THERMISTOR
Function
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
10,000 Ohms ± 2% at 25°C (77°F)
CAUTION
Use only Manitowoc thermistors.
Check Procedure
Verify that the thermistor resistance is accurate and corresponding to the high and low temperature ranges.
1.Disconnect the thermistor at the control board. Connect the ohmmeter to the isolated thermistor wire leads.
2.Using a temperature meter capable of taking readings on curved copper lines, attach the temperature
IMPORTANT
Do not simply “insert” the sensing device under the insulation. It must be attached to and reading the actual temperature of the copper liquid line.
3.With the ice machine running, verify that the temperature of the discharge line (step 2) corresponds to the thermistor resistance reading (step 1) as stated in the temperature/resistance chart.
