Each in-shot burner directs the air\/gas mixture into its heat-exchanger tube, where it ignites into a clean, controlled flame. Over years of firing cycles, burners can rust, clog with debris, or distort — causing noisy ignition, delayed lightoff, sooting, or uneven heating. Replacing worn burners restores crisp, efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 3\" burner throat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant OEM aluminized\/coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Slots onto burner rack \/ manifold, direct OEM fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \u0026amp; Amana AMS80905CXA and related 80% gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry controls flame shape, position, and combustion quality.

Generic burners can misdirect the flame, cause flame impingement or rollout, and reduce efficiency. For a combustion component, OEM fit is strongly recommended — and replace all burners as a matched set for even firing.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Shut off gas and power. Remove the burner-compartment door, disconnect the igniter\/flame sensor as needed, and slide the burners off the rack. Install the new burner in the same position, ensuring proper alignment with the orifice and heat-exchanger tube. Recommended for experienced DIYers or an HVAC technician — verify a clean blue flame and correct combustion after service.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eRestore clean, efficient heat with a genuine Goodman B4022700 in-shot burner.\u003c\/em\u003e\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057709269363,"sku":"GOODMAN-7119","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-ams80905cxa-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
