The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification sensor built for the GKS90905DXAD gas furnace and compatible GKS90 series models. It confirms the presence of a burner flame within seconds of ignition; if it cannot detect flame, the control board closes the gas valve for safety. A dirty, cracked, or worn flame sensor is one of the most common causes of furnace short-cycling and intermittent no-heat calls.
This genuine OEM sensor delivers the correct rod length, bracket geometry, and micro-amp signal the Goodman control board expects. Generic sensors can produce weak or inconsistent flame-current readings, causing the board to nuisance-trip even when the burner is lit. For a reliable, code-correct flame-proving signal, OEM is the safest choice.
Easy (2/5). Cut power at the disconnect, remove the single mounting screw, unplug the sensor wire, install the new sensor, and reconnect. The job typically takes 10–15 minutes. If the furnace continues to fault after replacement, have a licensed technician inspect the control board and ignition circuit.
