Restore reliable ignition with the genuine Goodman 0130F00010S Flame Sensor, built for the Goodman/Amana DMP125-52AB furnace. The flame sensor confirms the burner has lit by measuring the tiny microamp current that flows through an established flame (flame rectification). When the rod becomes oxidized or cracked, the control board can't verify flame and shuts the gas valve — causing short cycling, repeated ignition attempts, or a no-heat lockout. Replacing it is one of the most common furnace repairs.
OEM vs. Generic: The OEM 0130F00010S uses the correct rod length, alloy, and ceramic insulator so the flame signal reads within the board's expected range and the mounting bracket lines up exactly. Generic sensors may have weaker signal output or a mismatched bend, leading to nuisance faults. For dependable flame verification, choose OEM.
Install difficulty: ⭐ Easy. Typically a single mounting screw and one spade connector. Shut off power and gas, remove the old sensor, install the new one, and reconnect. A 10-minute repair for most DIYers — no calibration needed.
