A fault code identifies what the control detected, not which part failed. A sensor error can be the sensor, the harness, the connector, or the board reading it. Many Lynx appliances have no diagnostic display at all — mechanical valves, thermocouples and spark ignition report nothing. If yours shows no code, describe the symptom when you call.
