Each in-shot burner directs a precise fuel-air mixture into a heat-exchanger tube, producing a stable, evenly distributed flame for efficient combustion. Over time burners can rust, clog with debris, or distort — causing rough ignition, uneven flame, delayed light-off, or sooting. Replacing worn burners restores clean, quiet, efficient heating and helps protect the heat exchanger.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eComponent Type: In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eSize: 3-inch\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (80% AFUE two-stage)\u003c\/li\u003e\n\u003cli\u003eFits Model: AMVC81005CNBA\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eNote: Furnaces use one burner per heat-exchanger tube — order the full set for a complete rebuild\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e burner matches the exact venturi, orifice alignment, and slot pattern that Goodman engineered for correct flame characteristics and proper flame-sensor coverage. \u003cstrong\u003eGeneric\u003c\/strong\u003e burners may fit physically but can alter flame shape and combustion tuning.
