The genuine Goodman B4022700 3" In-Shot Burner is the OEM combustion burner for the ADVC80603BNBA 80,000 BTU gas furnace. In-shot burners fire natural or LP gas into the heat exchanger tubes; a worn, rusted, or misaligned burner causes rough ignition, flame roll-out, and uneven heating. Replacing the full burner set restores a clean, quiet blue flame across every tube.
OEM vs. Generic: The Goodman burner is stamped with the exact venturi throat and port pattern this furnace was rated with, guaranteeing the correct air/fuel mix and flame carryover between tubes. Generic burners can shift the flame profile, triggering flame-sensor dropouts or nuisance lockouts. OEM keeps combustion within spec.
Install difficulty: Moderate. Requires removing the burner assembly, noting orientation, and confirming smooth flame carryover on relight. Recommended for experienced DIYers or an HVAC technician. Shut off gas and power, and verify flame quality after installation.
