The Goodman 0130F00010S is a genuine OEM flame sensor (flame rod) for the WFD18070S3AXCB furnace. The flame sensor sits in the burner flame and uses flame rectification to confirm to the control board that the burners have lit. If the board does not detect a valid microamp signal within seconds of ignition, it closes the gas valve as a safety measure. A dirty or failed sensor is one of the most common causes of a furnace that lights briefly then shuts off.
The OEM 0130F00010S delivers a clean, stable flame signal matched to your furnace's control logic. Generic sensors sometimes use different rod alloys or lengths that produce a weaker signal, leading to intermittent lockouts. For consistent, trouble-free flame proving, the genuine part is the reliable choice.
Easy (1/5). One of the simplest furnace repairs — remove a single mounting screw, disconnect the spade terminal, and swap in the new sensor. It takes about 10 minutes with a nut driver. Always disconnect power first. Avoid touching the rod with bare fingers, as skin oils can contaminate the sensing surface.
