Each in-shot burner delivers a precisely shaped flame into the heat exchanger tube for efficient, even combustion. Burners that are rusted, cracked, or clogged with debris cause rough ignition, delayed light-off, or a noisy 'whoosh' on startup — replacing worn burners restores clean, quiet, reliable heating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurner size:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary fit:\u003c\/strong\u003e GDH80403ANAA gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (LP with proper conversion)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM burner\u003c\/strong\u003e is manufactured to the exact port geometry and venturi dimensions your furnace was engineered around, so flame carry-over, ignition timing, and CO output stay within spec. Generic burners may vary in port size or throat diameter, which can cause uneven flame, sooting, or nuisance flame-sensor faults. For a combustion component, OEM is the safe choice.
