The genuine OEM Goodman 0130F00010S flame sensor is the exact factory replacement rod for the WFD195090S4CAA gas furnace. The flame sensor confirms the presence of a burner flame using microamp rectification; when it becomes coated, corroded, or cracked, the control board can no longer verify flame and shuts down the gas valve — causing short-cycling, intermittent heat, or full ignition lockouts.
Generic flame rods often have the wrong rod length, bend, or terminal, producing a weak microamp signal that leads to nuisance lockouts even when the burner is lit. The genuine 0130F00010S delivers the exact rod geometry and material the WFD195090S4CAA control logic expects, restoring a strong, stable flame-sense signal.
Easy (2/5). Shut off power and gas first. Remove the single mounting screw, unplug the sensor wire, and install the new rod — avoid touching the sensing tip with bare hands. Replacement typically takes 10–15 minutes. If short-cycling persists after installation, have a technician verify the microamp reading and burner condition.
Eliminate flame-loss faults on your Goodman furnace with the genuine 0130F00010S flame sensor.
