Control board fault diagnosis

From Tech Sheet W10810403, p.8:

1.Access the service diagnostic mode using the tech sheet procedure. Record all stored fault codes from the error history, not just the most recent active code.

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 board for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
