Bin and Evaporator sensor are both open or

From Service Manual 704808, p.20:

1.Ohm both the bin and evaporator thermistors to check if they are within the expected resistance range.

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.
