The control and display sensor is open circuit

From Service Manual 600768, p.20:

1.Check if the connector of sensor is properly inserted into the control panel PCB. If persists, turn off the refrigerator and wait for 5 minutes.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
