Compressor runs over 3 hours when D-Sensor

From Service Manual 568348, p.40:

1.Check for possible sealed system issue; error code resets when D-sensor temperature is under -5°C (23°F) and compressor is off.

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.
