The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for the AMVC80804CNBD gas furnace and compatible Goodman and Amana models. This burner delivers the clean, stable flame your heat exchanger depends on, seating precisely into the burner box so flame carryover and ignition timing match factory specifications. When a burner rusts, cracks, or produces a lazy yellow flame, replacing it restores efficient, quiet combustion and eliminates rough ignition and delayed light-off.
Our OEM Goodman burner is machined to the exact port pattern and venturi throat of the original, guaranteeing correct flame carryover and manifold pressure. Generic burners are lower-cost but often vary in venturi geometry, which can cause uneven ignition, sooting, or nuisance flame-sensor lockouts. For a furnace, we recommend the OEM part for a precise, worry-free flame.
Easy (1 of 5). A single burner typically slides out and clips back in after removing the burner assembly bracket. Always shut off gas and power first. Replace all burners as a set if others show wear, and verify a crisp blue flame after restart.
