The Goodman B4022700 is a genuine 3-inch in-shot burner designed for AMS80904BNAA gas furnaces and compatible Goodman/Amana models. The in-shot burner delivers gas into the heat exchanger and anchors the flame for clean, efficient combustion. Corroded, clogged, or damaged burners cause rough ignition, delayed light-off, and uneven heating — installing a factory burner restores a crisp, blue flame and reliable startup.
This is the genuine Goodman burner engineered to the exact orifice alignment and flame-carryover spacing your furnace's manifold requires. Generic burners may be close dimensionally but can shift the flame pattern, causing flame-sensor dropout or lazy ignition. For heat-exchanger safety and code compliance, the OEM burner is the recommended choice.
Easy–Moderate (2/5). Requires shutting off gas and power, removing the burner assembly, and swapping the burner while keeping orifice alignment. Most furnaces use a full burner set, so inspect all burners together. Verify the flame pattern after startup. If you're unsure about gas connections, consult a licensed HVAC technician.
