In-shot burners deliver the fuel-air mixture into each heat exchanger tube, producing the clean blue flame the furnace relies on for efficient, safe heating.\u003c\/p\u003e\u003cp\u003eBurners can corrode, rust, or become clogged with lint and debris, which causes rough ignition, yellow or lazy flames, delayed light-off, and rumbling. A furnace uses one in-shot burner per heat exchanger cell, so replacing a damaged unit — or the full set — restores smooth, quiet ignition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003ePart Type: In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (convertible per furnace kit)\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated\/aluminized steel\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMS80704BXA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM burners are matched to the furnace's orifice size and manifold pressure, ensuring the correct flame profile and safe combustion. Off-brand burners may differ in port geometry, which can affect flame stability and trip the flame sensor or rollout switch. Because this part is combustion-critical, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires shutting off gas and power, removing the burner box, and carefully aligning the new burner with its orifice and igniter. After installation, verify a clean blue flame and proper flame-sensor reading. If you are not comfortable working with gas components, have a licensed HVAC technician perform the repair.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057691509107,"sku":"GOODMAN-6936","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-inch-in-shot-burner-for-ams80704bxa-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
