Each burner mixes gas and air and delivers the flame into one section of the heat exchanger. Rust, scale, or a warped port can cause rough ignition, delayed flame roll-out, or poor flame sensing on one tube — replacing the affected burner restores clean, even combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) burner, 3-inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana GMN080-4 (80,000 BTU) furnaces\u003c\/li\u003e\n\u003cli\u003eSold individually — order one per burner slot as needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is dimensioned to seat correctly against the manifold orifice and heat-exchanger port, so the flame lands where the sensor and igniter expect it. Generic burners vary slightly in length and venturi shape, which can misalign the flame. For a combustion component, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — about 15–20 minutes.
