The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for GDS81155CXA gas furnaces. It sits in the burner flame and confirms ignition by conducting a tiny microamp current back to the control board. When the rod oxidizes or cracks, the board can't prove flame and shuts the gas valve within seconds — the classic symptom is a furnace that lights then shuts off repeatedly (short-cycling).
The Genuine Goodman OEM sensor uses the correct rod alloy, length, and insulator so the control board reads a stable, in-spec flame signal. Generic rods often produce a weak microamp signal, leading to nuisance lockouts even when clean. For reliable ignition, choose OEM.
Easy – DIY friendly (★☆☆☆☆). Shut off power, remove one mounting screw, unplug the sensor wire, and install the new rod — handle the ceramic insulator carefully and avoid touching the metal rod with bare fingers. About 10 minutes with a 1/4" nut driver.
