The Goodman 0130F00010S Flame Sensor is a genuine OEM replacement engineered for the WFD195070S4CAA gas furnace and compatible Goodman/Amana models. The flame sensor confirms that a flame is present after ignition; when it fails or becomes coated with oxide buildup, the furnace board drops out the gas valve and locks out. Symptoms of a bad flame sensor include the burners lighting for a few seconds and then shutting off (short cycling), repeated ignition lockouts, and no-heat calls on an otherwise healthy furnace.
This is the factory OEM sensor, built to the exact rod length, mounting angle, and terminal spec Goodman engineered for this furnace — guaranteeing a proper microamp signal to the control board. Generic universal sensors can fit but often require bending the rod or adapting the connector, and a weak signal can cause intermittent lockouts. For a reliable, drop-in repair, OEM is the safe choice.
Easy (1/5). A single mounting screw and one push-on wire connector. Most homeowners can swap it in 10–15 minutes. Always shut off power and gas at the furnace before servicing. Tip: never sand the rod with heavy grit — replacing a worn sensor restores a clean signal far better than cleaning.
