The in-shot (monoport) burner directs the gas\/air mixture into the heat exchanger tube, where it is lit by the hot surface ignitor. Cracked, rusted, or clogged burners cause delayed ignition, uneven flames, and rollout — replacing the burner restores clean, quiet combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBurner style: In-shot (single-port)\u003c\/li\u003e\n\u003cli\u003eBurner tube diameter: 3 inches\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADV80703BXA furnace\u003c\/li\u003e\n\u003cli\u003ePart number: B4022700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e burner matches the factory port geometry and orifice alignment exactly, so flame characteristics and BTU output remain to spec. Generic universal burners often require re-drilling or shimming and can throw off the air-to-fuel ratio, leading to sooting or nuisance lockouts. For a furnace, we recommend OEM for safe, code-compliant combustion.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5).\u003c\/strong\u003e Requires shutting off gas and power, removing the burner assembly bracket, and swapping the individual burner.
