The B4022700 is a genuine OEM in-shot burner engineered for Goodman and Amana 80% AFUE gas furnaces, including the AMVC80805DXBD. Each burner delivers a stable, correctly shaped flame that fires cleanly into the heat exchanger, protecting efficiency and preventing sooting, delayed ignition, and roll-out faults. Furnaces typically use one burner per manifold port, so inspect all burners when replacing one.
The OEM B4022700 is dimensionally matched to the factory manifold and orifice spacing for a precise flame pattern and safe ignition timing. Generic burners may seat improperly or alter the flame geometry, risking flame-sensor and roll-out issues. For furnaces, we strongly recommend OEM.
Easy (2/5). Shut off gas and power, remove the burner assembly, swap the burner, and verify flame carry-over. Basic hand tools; 20–30 minutes for a qualified DIYer. Have a licensed HVAC technician verify combustion if unsure.
