Fridge defrost error - connector slipped out

From Service Manual 991410, p.22:

1.Disconnect MAIN PCB CN70 and read resistance between Orange and White wire terminals; 0 Ohm = heater short, infinite Ohm = wire cut or blown thermistor

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.
