Weight sensor error - value of A is negative as
From Service Manual 787609, p.21:
1.Check if turntable is placed over roller properly; check for foreign substance on weight sensor.
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.
