T1 temperature sensor out of range

From Service Manual 456526, p.18:

1.Check T1 sensor; system switches to T3 but still uses set point from T1 and turns on fan constant, making the cabinet run as single zone.

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.
