The Goodman 0130F00010S Flame Sensor is a genuine OEM replacement designed for the Goodman GMT070-3A gas furnace and compatible models. The flame sensor is a critical safety component that confirms the burner has ignited and signals the control board to keep the gas valve open. A dirty, cracked, or worn flame sensor is one of the most common causes of a furnace that lights briefly and then shuts down (short cycling on flame failure).
This is the factory-specified OEM sensor, machined to the exact rod length, mounting bracket, and terminal spec of your furnace — no bending, adapting, or guesswork. Aftermarket generics can vary in rod geometry and micro-amp signal strength, which may lead to intermittent flame-loss faults. For a safety-critical part like flame sensing, OEM is the recommended choice.
Easy (1/5). Typically a single mounting screw and one wire connector. Shut off power and gas, remove the old sensor, install the new one, and restore power. Most DIYers complete this in 10–15 minutes with a nut driver.
