The in-shot burner directs the gas-air mixture into the heat exchanger tube, where it ignites to produce the heat your system delivers to the home. A cracked, rusted, or sooted burner causes rough ignition, delayed light-off, yellow flame, and rollout faults — replacing it restores a clean, even blue flame and reliable starts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: 3\" in-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADS81155CNA gas furnace\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel with corrosion-resistant finish\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace burner assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a true \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e burner machined to factory port and flame-rod geometry, so flame sensing and ignition timing stay within spec. Aftermarket burners often vary in port size and length, which can throw flame-sense errors or uneven heating. For combustion components we recommend OEM for safety and a clean light-off.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — burners are accessed behind the gas manifold and typically replaced as a set.
