Bin thermistor is out-of-range (temperature

From Service Manual 167790, p.42:

1.Test the bin thermistor resistance and compare to Table C in Section 5.2. Replace if out of specification.

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.
