Software configuration / program mismatch —

From Service Manual 889347, p.39:

1.Rotary: Replace cycle selector switch and retry; if problem persists, replace main board. Push button: Replace Electronic Control Board.

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.
