Each in-shot burner meters and directs the gas\/air mixture into a single heat-exchanger tube, so a cracked, corroded, or misfiring burner leads to rough ignition, delayed light-off, and uneven heating. Replacing it with the correct factory part restores clean, quiet combustion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (monoport) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal size:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e AMS80904BXAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas \/ LP (per furnace configuration)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Coated steel for corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the factory Goodman burner, built to the exact orifice alignment and flame geometry the AMS80904BXAA was certified with. Generic universal burners are cheaper but often require re-shimming and can shift flame position enough to trip the flame sensor or rollout switch. For a furnace-grade combustion part, we recommend the OEM unit to preserve safe, in-spec operation.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy\u003c\/strong\u003e for an experienced DIYer. Shut off gas and power, remove the burner assembly bracket, slide out the old burner, and seat the replacement in the same orientation. Verify orifice-to-burner alignment before restoring power. If you are not comfortable working near a gas manifold, use a licensed HVAC technician.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCompatibility tip: confirm your furnace uses 3-inch in-shot burners and count how many your unit requires — many 80% furnaces use one burner per heat-exchanger tube.\u003c\/em\u003e\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057707073907,"sku":"GOODMAN-7095","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-ams80904bxaa-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
