The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-proving rod for the ADSH800804BXAC gas furnace. The sensor uses flame rectification — a small microamp current that flows only when the rod is engulfed in flame — to confirm to the control board that ignition succeeded. If no flame signal is detected, the board closes the gas valve within seconds, preventing raw gas from entering the combustion chamber. A weak or dirty flame sensor is one of the most common causes of short-cycling and ignition lockout.
OEM vs. Generic: The OEM 0130F00010S uses the correct rod length, alloy, and mounting geometry so it sits properly in the flame and produces a strong, stable signal. Generic sensors may read a marginal microamp value that works when new but drops below the lockout threshold as it ages, causing intermittent no-heat faults. For reliable flame proving, the OEM rod is recommended.
Install difficulty: Easy (1/5). Shut off power, remove one mounting screw, disconnect the wire, and swap the sensor. Handle the ceramic insulator carefully and avoid touching the rod. After installation, verify the flame-sense microamp reading is within Goodman's specification.
