It is a direct-fit replacement for the \u003cstrong\u003eAMS81405DNBC\u003c\/strong\u003e gas furnace and is used across many single- and multi-stage Goodman and Amana furnaces. Rusted, warped, or carbon-clogged burners cause rough ignition, flame rollout, and poor flame-sensor readings — replacing worn burners restores clean blue-flame lighting across the manifold.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (venturi) burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003ePrimary Fit: Goodman AMS81405DNBC furnace\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify orifice sizing for LP conversions)\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine \u003cstrong\u003eOEM\u003c\/strong\u003e burners are stamped to the correct venturi throat and port pattern so the flame carries evenly from burner to burner.
