The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for the GMP125-5 gas furnace and compatible models. It uses the microamp current that flows through the flame to prove ignition to the control board. When the rod oxidizes or cracks, the board can't sense flame and shuts the gas valve within seconds — producing short cycling, repeated ignition attempts, and hard lockouts. A fresh OEM sensor restores a strong, stable flame signal.
This OEM sensor uses the correct rod length, alloy, and insulator so the flame signal reads within the board's expected microamp range. Generic rods may sit at the wrong depth in the flame and read low, causing the same lockouts you're trying to fix. OEM is recommended.
Easy (1/5). Disconnect power, remove one mounting screw, pull the spade terminal, and install the new rod — don't touch the rod with bare fingers. Verify a steady flame signal after startup.
