The Goodman 0130F00010S flame sensor is a genuine OEM replacement for the GKS90905DXAF gas furnace. The flame sensor confirms that the burners have ignited by generating a micro-amp rectification signal to the control board. When it becomes coated in oxide or fails, the furnace lights briefly then shuts down — the classic short-cycle / no-heat lockout. Replacing this inexpensive part is one of the most common and effective furnace repairs.
This genuine Goodman OEM sensor uses the correct rod alloy and bracket angle for reliable flame proving. Generic sensors may sit at the wrong depth in the flame envelope, producing a weak signal and intermittent lockouts. For dependable ignition, the OEM part is the right choice.
Easy (1/5). Turn off power, remove one mounting screw, unplug the single wire lead, and swap. Takes about 10 minutes. Tip: gently clean the surrounding burner area and never sand a new sensor — handle it by the ceramic base only.
Verify the part number on your furnace nameplate before ordering.
