The Goodman 0130F00010S is a genuine OEM flame sensor engineered for the Goodman GDT045-3A gas furnace and compatible models. This flame-rectification rod sits in the burner flame and confirms to the control board that ignition has actually occurred by conducting a tiny microamp current. If the board doesn't sense flame, it shuts the gas valve within seconds as a safety measure. A dirty, oxidized, or cracked flame sensor is one of the most common causes of a furnace that lights briefly and then shuts off, short-cycles, or locks out — replacing it restores reliable heating.
The OEM 0130F00010S uses the correct rod length, alloy, and bracket geometry to deliver a stable flame signal your specific control board expects. Generic sensors may sit at the wrong depth or produce a weak signal, causing nuisance lockouts. For dependable ignition, OEM is the preferred choice.
Easy (1/5) — Cut power, remove one mounting screw, unplug the wire, and install the new sensor. A quick, common DIY furnace repair completed in minutes.
