Internal generator error, sync in the 2 cook
From Service Manual 518155, p.47:
1.Test cables and connections on right generator circuit board. Replace the right side generator circuit 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.
