The Goodman B4022700 is a genuine OEM 3-inch in-shot burner for the Goodman/Amana AMH80604BNBA gas furnace. In-shot burners direct a precise jet of air-gas mixture into the heat exchanger tubes, where the crossover igniter lights the first burner and flame carries across the bank. Rusted, clogged, or misaligned burners cause delayed ignition, roll-out, sooting, and uneven heating.
The OEM B4022700 has the exact port diameter and venturi geometry Goodman engineered for correct flame shape and BTU input. Aftermarket burners can vary in orifice alignment, leading to poor flame carryover and lazy/yellow flames. Replace the full burner set together for even performance.
Moderate (3/5). Requires removing the burner assembly, gas manifold access, and correct realignment with the igniter and flame sensor. A combustion check is recommended after service. Best performed by an HVAC professional. Always shut off power and gas first.
