The Goodman 0130F00010S is a genuine OEM flame sensor (flame rod) for the GCH90905DXAB gas furnace. This component confirms the presence of a burner flame by conducting a microamp rectification signal back to the control board. When the sensor becomes coated in oxide or cracks, the board fails to prove flame and shuts off the gas valve within seconds — the classic symptom of a furnace that lights then short-cycles. Replacing this sensor is one of the most common no-heat fixes.
OEM Goodman sensors use the correct rod alloy, length, and mounting bracket for an accurate, stable flame signal and exact bolt-up. Generic sensors may sit at the wrong depth in the flame, produce weak microamp readings, and cause intermittent lockouts. For a reliable flame-proving circuit, choose OEM.
Easy to Moderate (2 of 5). Turn off gas and power, remove the single mounting screw, unplug the wire lead, and install the new sensor. Do not touch the metal rod with bare fingers. If your furnace still short-cycles after replacement, have a licensed HVAC technician verify the control board and grounding.
