Restore dependable ignition to your Goodman GMN100-4 gas furnace with the genuine OEM 0130F00010S flame sensor. The flame sensor (flame rod) confirms that the burners have lit and generates the microamp signal the control board needs to keep the gas valve open. When it fails, the furnace typically lights briefly then shuts down on a flame-proving lockout, cycling repeatedly without producing steady heat.
The OEM Goodman 0130F00010S is the factory-specified rod with exact mounting geometry and rod length for correct flame immersion — the safest, longest-lasting choice. Our generic replacement is a lower-cost, functionally equivalent flame sensor that fits the same bracket and works well for budget-minded repairs. Both restore proper flame signal.
Easy (1 of 5). A 15-minute repair for most homeowners: cut power, remove the single mounting screw, unplug the spade wire, and swap the sensor. Lightly clean any new corrosion and avoid touching the rod with bare fingers. Always shut off gas and electrical power before servicing.
