The in-shot burner directs a precise gas\/air mixture into the heat exchanger, delivering clean, efficient combustion and stable flame carryover across the burner rack. Over time, burners corrode, clog with rust flakes, or develop uneven flame patterns that trigger flame-sensor faults and short cycling — replacing the affected burner restores proper ignition and heat output.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eBurner diameter: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas \/ LP compatible furnace platform\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS80703ANA and related 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant aluminized steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 matches the exact port geometry and flame-crossover spacing of your furnace's burner assembly, ensuring correct BTU delivery and clean lightoff. Generic burners may vary slightly in orifice alignment, which can cause delayed ignition, sooting, or flame-sensor dropout. For a heating appliance, the OEM part is the safest and most reliable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eRating: Easy (2\/5).\u003c\/strong\u003e Requires shutting off gas and power, removing the burner-box cover, and sliding the burner off the manifold orifice. Most DIYers complete a single-burner swap in 20–30 minutes. Always verify flame quality and check for gas leaks after installation. If you are uncomfortable working near the gas manifold, consult a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058032755059,"sku":"GOODMAN-9585","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-dms80703ana-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
