The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for GCH950703BXAD gas furnaces and compatible Goodman/Amana models. It confirms the burner has lit by sensing the micro-amp flame-rectification current; when the rod becomes coated, cracked, or weak, the control board can't verify flame and shuts the gas valve — producing short cycling, ignition lockout, or a furnace that lights briefly then quits.
The OEM 0130F00010S uses the correct rod length, bend, and mounting so it sits properly in the flame envelope for a strong, stable signal. Generic flame sensors cost less and often physically fit, but variations in rod position or alloy can yield a marginal micro-amp reading that causes intermittent lockouts. For a furnace you rely on through winter, the OEM sensor delivers the most dependable flame signal.
Roughly 15 minutes. Cut furnace power, remove the single mounting screw, unplug the sensor wire, and install the new 0130F00010S — handling the rod by its base only, never touching the sensing element. Restore power and confirm the burner stays lit through a full cycle. Tip: if you're troubleshooting short cycling, always try cleaning or replacing this sensor first — it's the single most common cause.
