The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for the ADVC81005CNAA furnace and other compatible Goodman and Amana gas furnaces. In-shot burners deliver the fuel/air mixture directly into the heat exchanger tubes for efficient, quiet combustion. Replacing a corroded or rust-flaked burner restores smooth ignition and consistent flame carryover across the burner rack.
The OEM B4022700 is calibrated to Goodman's exact orifice spacing and flame-carryover geometry. Generic burners can shift the flame pattern, cause delayed ignition or roll-out, and trip safety limits. Replace burners as a full matched set for best results.
Moderate (3/5). Requires shutting off the gas, removing the burner assembly, and confirming proper flame alignment on restart. Best performed by a qualified HVAC technician.
