F. Thermistor Check

To check thermistor resistance, follow the steps below.

1)Turn off the power supply.

2)Remove the front panel. Move the control switch to the "OFF" position.

3)Remove the control box cover.

4)Remove the thermistor from the refrigerant tubing.

5)Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 min.

6)Disconnect the thermistor connector from CB K3 connector and check the resistance between thermistor leads. Normal range is 4.7 to 6.2 kΩ. If outside the normal range, replace the thermistor. See "IV.B. Component Service Information." If within the normal range, continue to the next step.

7)Replace the thermistor in its correct position. See "IV.B. Component Service Information."

8)Reconnect the thermistor connector to CB K3 connector.

9)Replace the control box cover in its correct position.

10)Move the control switch to the "ICE" position.

11)Replace the front panel in its correct position.

12)Turn on the power supply.

13)Once the harvest cycle starts (Comp energizes), begin timing the harvest cycle.

14)The harvest timer and harvest cycle should terminate within 2 to 5 min. If the harvest cycle does not terminate within 2 to 5 min., replace CB.
