In-shot burners fire a precise gas\/air mixture into each heat-exchanger tube; a corroded, clogged, or misaligned burner causes rough ignition, delayed light-off, flame rollout, or uneven heat. Replacing worn burners restores clean, quiet, on-demand ignition and proper flame geometry.\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 burner (single)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMEC800403ANAA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Directs gas\/air mix into the heat exchanger for ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually — order one per burner position\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM B4022700 is built to the exact venturi diameter and port pattern the furnace was engineered around, so flame carry-over and burner-to-orifice alignment stay correct. Generic burners can shift the flame profile and trigger flame-sensor or rollout faults.

Shut off gas and power, remove the burner assembly bracket, slide out the old burner, seat the new burner over the orifice with correct alignment, and reassemble. Inspect flame sensor and igniter while apart. Plan on 30–60 minutes; verify a crisp blue flame and no rollout after restart.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057132749171,"sku":"GOODMAN-B4022700","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-in-shot-burner-for-amec800403-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
