The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for the AMVC80603BXCA 80% AFUE variable-speed gas furnace. The in-shot design meters gas into the heat-exchanger tube for a stable, quiet blue flame, ensuring efficient combustion and dependable heating each cycle. Replacing a warped, rusted, or crossover-fouled burner restores proper flame carryover and prevents delayed ignition and rollout faults.
Our OEM Goodman burner matches the factory flame profile, port geometry, and carryover slot alignment exactly — critical for passing flame sensing and limit checks. Generic burners often vary in port depth and mounting hook length, causing rough ignition, sooting, or nuisance lockouts. For safety-critical combustion parts, OEM is the reliable choice.
Difficulty: Easy (2/5). Shut off gas and power, remove the burner box cover, slide the old burner off its rack, and seat the replacement so the carryover slot aligns with neighboring burners. Cycle and verify a clean blue flame. Typical time: 15–20 minutes. Professional installation recommended for gas work.
