The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM burner for Goodman and Amana gas furnaces, including the ACVC80803BXBC. In-shot burners direct the gas/air mixture into each heat-exchanger tube for clean, efficient combustion. Replacing a corroded, cracked, or rust-clogged burner restores proper flame quality and prevents rollout, sooting, and uneven heating.
The OEM B4022700 delivers the exact orifice alignment and flame geometry the furnace was designed for. Generic burners can alter the air/fuel mix, causing poor ignition, flame rollout, or excess carbon monoxide — a safety risk. For a combustion component, OEM is strongly recommended.
Moderate — Requires removing the burner assembly and matching burner-to-orifice alignment. Best performed by a licensed HVAC technician. Shut off gas and power, replace burners as a matched set when possible, and verify flame appearance and CO levels after service.
Confirm fitment against your furnace's parts diagram before ordering.
