In-shot burners deliver the gas\/air mixture into the heat exchanger tubes for clean, efficient combustion. A furnace uses one burner per heat-exchanger tube, so worn, rusted, or clogged burners should be replaced as a matched set for even flame distribution.\u003c\/p\u003e\u003cp\u003eSymptoms of a failing burner include delayed or rough ignition, flame rollout, sooting, uneven heating, or a burner that fails to light. Replacing the burners restores a crisp, blue flame and proper heat transfer.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3-inch (nominal) throat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \u0026amp; Amana AMH81005CNBA and related furnace platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine Goodman B4022700 is stamped and ported to the factory venturi geometry that matches the furnace's gas orifice and manifold pressure. This ensures the correct air\/fuel mixture and a stable flame. Generic burners may have slightly different port patterns or throat depth, causing flame instability, noise, or incomplete combustion. For safe, code-compliant operation, use the OEM burner.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Moderate (3\/5). Requires shutting off gas and power, removing the burner assembly bracket, sliding out the old burner, and aligning the new burner over the orifice and flame sensor path. Basic hand tools needed. If you are not comfortable working around gas connections, have a licensed HVAC technician perform the replacement and verify flame quality afterward.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057637507443,"sku":"GOODMAN-5926","price":16.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-amh81005cnba-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
