Each in-shot burner directs a precise gas-air stream into a single heat-exchanger tube, where it ignites and produces the clean, blue flame your furnace relies on for efficient heating. Over time burners can corrode, clog with rust and debris, or develop uneven flame patterns that trigger flame-sensor faults and short cycling. Replacing worn burners with the correct OEM unit restores smooth ignition and quiet operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GDH80403AXAA\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas \/ LP (matches furnace orifice)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman burners are stamped to the exact venturi throat, port pattern, and mounting-slot dimensions of your furnace manifold. Generic burners may bolt in but often alter the flame characteristics, leading to lazy flames, sooting, or nuisance lockouts.
