The Goodman 0130F00010S flame sensor is the genuine OEM flame-rectification rod for your AMSS921004CNAA gas furnace. After ignition, the control board sends a micro-amp signal through this rod to confirm a flame is present; if the current drops too low, the board closes the gas valve as a safety measure. A dirty, corroded, or cracked flame sensor is the single most common reason a furnace lights and then shuts off after a few seconds, repeatedly cycling and eventually locking out on flame loss.
This genuine Goodman OEM sensor uses the correct rod length, alloy, and ceramic insulator for reliable micro-amp signal on your board. Generic rods can sit at the wrong depth in the flame or degrade quickly, causing repeat flame-loss faults. For a dependable, one-and-done repair, choose OEM.
Easy (1/5). One mounting screw and one push-on wire connector — usually a 10-minute job. Disconnect furnace power first. Tip: gently clean the burners and inspect wiring while you're in there.
