The Goodman 0130F00010S is a genuine OEM flame sensor (flame-rectification rod) for the GDH80403AXBC gas furnace and compatible Goodman/Amana models. The flame sensor confirms to the control board that the burners have actually lit; if it fails to detect flame within the trial-for-ignition window, the board closes the gas valve for safety. A worn, corroded, or cracked sensor is the single most common cause of furnace short cycling and hard lockouts during heating season.
The OEM 0130F00010S uses the correct rod length, angle, and alloy to sustain a stable microamp signal in your specific burner flame. Generic sensors are often bent to fit and can sit too far from the flame, producing a weak signal that trips the board even when the burner is lit. Genuine OEM restores the microamp reading the control expects and preserves reliable ignition.
Rating: Easy (2/5). Replacement is a one-screw job: cut power, disconnect the single wire, remove the old rod, and install the new sensor — typically under 15 minutes. Avoid touching the rod with bare fingers, and if short cycling persists, have a technician verify flame-signal microamps.
