In-shot burners deliver the gas\/air mixture into the heat exchanger for combustion. Over time, burners can rust, clog with debris, or develop uneven flame patterns that cause delayed ignition, sooting, or flame-sensor faults. Installing fresh OEM burners restores a clean, blue, evenly distributed flame across every tube.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch in-shot burner\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GMPN100-4 (and select Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eType: Single-port in-shot gas burner\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry directly affects flame quality and combustion safety. Generic burners may have slightly different port sizing or orifice alignment, leading to rollout, poor ignition, or incomplete combustion. The \u003cstrong\u003egenuine OEM B4022700\u003c\/strong\u003e matches the factory bore, length, and mounting exactly, so flames light instantly and carry over cleanly between tubes.

Always shut off gas and power first. Because combustion and gas safety are involved, we strongly recommend a licensed HVAC technician for this repair.
