Evaporator thermistor failure detected during
From Tech Sheet W12764560, p.12:
1.Check evaporator thermistor resistance; thermistors are auto-tested after Step 4 (heater off).
2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).
3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
