In-shot burners inject a precise gas\/air mixture into each heat-exchanger tube, where it ignites into a stable inner cone that transfers heat efficiently and burns cleanly. Over years of cycling, burners can rust, clog with scale, or develop erratic flames that cause delayed ignition, roll-out, or a flickering flame-sense signal. Replacing worn burners with the correct OEM part restores smooth light-off and even, quiet combustion across the burner rack.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: in-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 in\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18045S3AXCB furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003cli\u003eFuel: natural gas \/ LP (with matched orifice)\u003c\/li\u003e\n\u003cli\u003eMaterial: corrosion-resistant coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM Goodman burner is drilled and ported to the exact venturi geometry Goodman engineered for this furnace, so the flame profile and BTU delivery match spec. Generic burners may vary in port size and length, which can shift the air-fuel mixture and cause sooting or ignition faults. For safe, in-spec combustion, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate.\u003c\/strong\u003e Requires removing the burner assembly, transferring or replacing each burner, and verifying alignment with the igniter and flame sensor.
