In-shot burners deliver a precise fuel-air jet into the heat exchanger tubes for clean, efficient ignition. Over time, burners rust, warp, or clog with debris, causing rough ignition, delayed lightoff, uneven flames, or lockouts. Installing the correct OEM burner restores a crisp blue flame and reliable heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) combustion burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WGFM28070V4BXAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM burner\u003c\/strong\u003e is stamped with the factory port size and venturi geometry that matches the furnace's gas orifice and manifold pressure. Generic burners with a slightly different port can shift the air-fuel mixture, causing sooting or noisy ignition.
