D. Thermistor Check
To check thermistor resistance, follow the steps below.
1) Move the control switch to the "OFF" position.
2) Unplug the appliance.
3) Remove the control box cover.
4) Remove the thermistor from the evaporator.
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 and check the resistance between
thermistor leads. Normal range is 5.5 to 6.5 kΩ. If outside the normal range, replace
the thermistor. See "IV.B. Important Notes for Component Replacement." If within the
normal range, continue to the next step.
7) Replace the thermistor in its correct position. See "IV.B. Important Notes for Component
Replacement."
8) Reconnect the thermistor connector to CB.
9) Replace the control box cover in its correct position.
