The in-shot burner delivers the fuel-air mixture into the heat exchanger, so a clean, correctly seated burner is essential for reliable ignition, quiet operation, and safe combustion. Over time carbon buildup, corrosion, or a warped venturi can cause delayed ignition, roll-out, or short cycling — replacing the burner restores factory performance.\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 (single-port) burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (LP with conversion kit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH80403AXBC and related Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminized steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine OEM burner matches the exact venturi throat diameter and port geometry the furnace was designed around, ensuring proper flame carry-over between adjacent burners. Generic burners are cheaper but often have slightly different orifice alignment, which can cause uneven flames, nuisance flame-sensor faults, and inconsistent heat output. For a combustion component we recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2\/5).\u003c\/strong\u003e Requires shutting off gas and power, removing the burner assembly bracket, and reseating the burner over the orifice. Roughly 20–30 minutes for a competent DIYer. Because this is a gas-carrying part, verify flame appearance and check for leaks with soap solution after install, or have a licensed HVAC technician perform the swap.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057601266035,"sku":"GOODMAN-4985","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-amh80403axbc-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
