The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for ADVC80805CXBA gas furnaces and other compatible Goodman/Amana 80% AFUE models. This burner delivers the fuel/air mixture to the heat exchanger for stable, quiet ignition and clean combustion. Over time in-shot burners can distort, rust, or clog with debris, causing rough ignition, delayed light-off, flame roll-out, or a burner that fails to fully carry across. Installing a fresh factory-spec burner restores reliable heating and safe operation.
Our OEM Goodman B4022700 matches the exact port geometry, orifice alignment, and mounting of the original so the flame profile and combustion stay within factory spec. Generic burners are a budget alternative but can differ slightly in port size or length, which may affect ignition reliability and flame stability. For safety-critical combustion components we recommend OEM.
Easy–Moderate. Requires shutting off gas and power, removing the burner assembly, and swapping the burner. Basic hand tools and comfort working around a gas manifold are needed. If you are not confident working with gas, use a licensed HVAC technician.
