From Service Manual 621050, p.22:

1.Check if the connector for the relevant room is inserted well; measure resistance at both sensor terminals (check for 0 ohm or infinite ohm).

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.
