In-shot burners deliver a precise fuel-air jet into the heat exchanger for clean, quiet, efficient combustion. Rust, scale, or spider\/insect blockage inside a burner causes rough ignition, delayed light-off, sooting, and roll-out faults — replacing worn burners restores smooth, even flame carryover across the manifold.\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \u0026amp; Amana AMS80603AXAA and compatible 80% gas furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Meters fuel-air mixture into the heat exchanger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Single burner (order one per burner position)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM B4022700 matches Goodman's exact orifice alignment, venturi geometry, and flame characteristics, so light-off and carryover are correct out of the box. Generic burners can misalign with the manifold spuds and produce uneven or noisy flames. For safe, reliable combustion, use the OEM burner and replace as a matched set when possible.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Moderate (3\/5). Shut off gas and power, remove the burner cover and manifold, slide out the old burner, and seat the new one over the correct orifice with proper carryover alignment. Typically 30–45 minutes. Because this is a gas combustion component, a qualified HVAC technician should verify flame, gas pressure, and roll-out safety after installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057686266227,"sku":"GOODMAN-6789","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-inch-in-shot-burner-for-ams80603axaa-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
