The Goodman 0130F00010S Flame Sensor is a genuine OEM flame-rectification rod for the AMH80904BXCA gas furnace. It sits in the burner flame and confirms ignition by carrying a micro-amp rectified signal back to the control board. When the sensor is dirty, cracked, or degraded, the board fails to prove flame and shuts the gas valve — the classic cause of a furnace that lights briefly then short-cycles or drops to a no-heat lockout.
The OEM 0130F00010S uses the correct rod length, insulator, and bracket so it lands precisely in the flame envelope and produces a stable signal your board recognizes. Generic sensors often sit too shallow or deep in the flame, yielding weak or erratic micro-amp readings and repeat lockouts. For reliable flame proving, OEM is the safer buy.
Easy (1/5). One screw and one spade connector — typically a 5-minute swap. Turn off power and gas first. If replacing due to intermittent operation, also inspect the ground path and burner alignment. A good sensor should read roughly 2–6 micro-amps in normal operation.
