The 0130F00010S is a genuine OEM Goodman flame sensor (flame rod) for the WFD18045S3AXCB furnace and compatible Goodman/Amana models. The sensor uses flame rectification to prove that the burner has actually ignited: it passes a small microamp signal through the flame back to the control board. If no flame is detected, the board closes the gas valve — a core safety function. A dirty or failed flame sensor is one of the most common causes of a furnace that lights briefly then shuts off (short-cycling).
The OEM 0130F00010S has the exact rod length, mounting bracket, and terminal that your control board expects, delivering a stable microamp signal. Generic sensors can sit at the wrong depth in the flame or give a weak signal, causing intermittent lockouts. For reliable ignition proving, the genuine part is the better choice.
Easy (2/5). Shut off power and gas, remove one mounting screw, disconnect the single spade wire, and install the new sensor. Avoid touching the rod with bare fingers. This is a common, low-cost repair that often restores a short-cycling furnace to normal operation.
