The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for AMVC81005CXBD and compatible Goodman/Amana two-stage gas furnaces. Each in-shot burner directs and shapes the gas flame into the heat exchanger tube for clean, efficient combustion. Because Goodman and Amana share the Daikin manufacturing platform, this burner is a direct fit across many AMVC/GMVC-series furnaces.
This is the factory OEM burner — dimensions, port spacing, and flame geometry match the original exactly, protecting flame-sensor and igniter alignment. Generic burners are cheaper but often mis-shape the flame, causing sooting, delayed ignition, or flame-rollout faults. For a combustion component, OEM is the safe choice.
Moderate. Requires shutting off gas and power, removing the burner assembly, and swapping the burner while keeping port alignment. Budget 30–45 minutes; professional installation recommended if you are not comfortable working with gas components.
