In-shot burners deliver the gas-air mixture into the heat exchanger for clean, efficient combustion. Over time, rust, spider webs, or scale can obstruct the burner venturi and cause rough ignition, delayed light-off, or flame rollout — replacing worn burners restores smooth, quiet startup and safe operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal size:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (LP with proper conversion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminized steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80703ANAA and compatible Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is a factory-original Goodman part machined to exact venturi and port tolerances, so the flame pattern matches the manufacturer's heat-exchanger design. Generic burners are cheaper but often vary in throat diameter and orifice alignment, which can shift flame color, increase sooting, or trip the flame sensor. For a furnace safety component, OEM is the recommended choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation difficulty:\u003c\/strong\u003e Easy to Moderate. Replacement typically takes 20–40 minutes with basic hand tools — shut off gas and power, remove the burner assembly, swap the affected burner, and verify orifice alignment before relighting. We strongly recommend a licensed HVAC technician confirm proper flame sensing and combustion after install.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057690100083,"sku":"GOODMAN-6885","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-ams80703anaa-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
