The Goodman B4022700 is a genuine OEM 3-inch in-shot burner built for the AMVC80803BNCA variable-capacity gas furnace and compatible Goodman/Amana multi-burner assemblies. Each in-shot burner directs a precise gas/air mixture into the heat exchanger for clean, efficient blue-flame combustion. Rust, scale, or spider/insect blockage inside a burner causes lazy yellow flames, delayed ignition, rollout, and rumbling — replacing the affected burner(s) restores reliable, quiet firing.
The OEM Goodman burner matches the factory port pattern and orifice alignment for correct flame carry-over and heat-exchanger targeting. Our generic-equivalent in-shot burner meets the same 3" spec at a lower cost. For best results, replace all burners in the assembly together so combustion stays balanced across the manifold.
Rating: Moderate (3/5). Roughly 30–45 minutes. Shut off gas and power, remove the burner box/manifold, slide out the old burner, seat the new one over its orifice with proper spacing, then reassemble and verify a clean blue flame at startup. Because this is a gas-combustion component, a licensed HVAC technician is strongly recommended.
