Each burner directs a metered stream of gas and primary air into the heat exchanger tube for clean, quiet, and efficient combustion. Over years of firing cycles, burners can warp, rust, or develop misaligned flame patterns that cause delayed ignition, roll-out, or short cycling — replacing them restores a crisp, blue flame and reliable heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eBurner tube diameter: 3 inches\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (LP with proper orifice)\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VMS80403AXAA and compatible 80% gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 is manufactured to Goodman's exact port spacing, air-shutter geometry, and heat-exchanger alignment, ensuring a factory-correct flame and warranty-safe repair.
