The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM combustion component built for GMPN080-4 gas furnaces. Each in-shot burner directs a precise stream of gas into the heat exchanger, producing the clean, stable flame your furnace needs for efficient, safe heating. Over time burners corrode, clog with debris, or develop uneven flame patterns — replacing them with exact-fit OEM parts restores proper ignition and even heat output.
Generic burners can vary in port size and alignment, causing rough ignition, delayed lighting, or sooting that shortens heat exchanger life. The genuine Goodman B4022700 matches the factory venturi geometry and port pattern exactly, delivering a consistent flame and proper gas-air mixing. For multi-burner furnaces, replace all burners as a set for uniform performance.
Easy to Moderate (2/5). Shut off gas and power, remove the burner assembly bracket, slide out the old burner, and seat the replacement over the orifice. Verify flame quality on startup. Professional installation is recommended for gas-fired equipment.
Keep your GMPN080-4 firing clean and efficient. This OEM in-shot burner ships fast with an exact-fit guarantee.
