The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for the AMS80403AXAD 80% AFUE gas furnace and compatible Goodman/Amana models. The sensor confirms to the control board that the burner has actually lit; if it cannot detect a stable flame current, the board shuts the gas valve within seconds as a safety measure. A dirty or failed flame sensor is the single most common cause of a furnace that lights briefly and then shuts off (short-cycling) or locks out on ignition fault.
OEM sensors use the correct rod length, alloy, and bracket geometry so the flame envelope covers the rod for a strong, stable signal. Generic sensors often sit at the wrong depth and produce a weak micro-amp reading that trips the board intermittently. OEM is recommended for reliable ignition.
Easy (1/5). One of the simplest furnace repairs: kill power, remove the single mounting screw, unplug the wire lead, and install the new rod. A common five-minute fix for no-heat calls. Verify a full, stable heat cycle after installation.
