The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM replacement designed for the Amana/Goodman AMVC80604BXBA gas furnace and compatible 80% AFUE models. This burner directs the air/gas mixture into the heat exchanger for clean, efficient combustion. A cracked, rusted, or misaligned burner causes rough ignition, delayed light-off, and yellow flames — replacing it restores a crisp blue flame and quiet, reliable heating.
Our OEM Goodman burner matches the exact venturi geometry and port pattern of the factory part, ensuring correct flame carryover between burners. Generic burners are budget-friendly but may vary slightly in port sizing, which can affect ignition timing and flame stability. For furnaces under warranty, OEM is strongly recommended.
Easy (2/5). Requires shutting off gas and power, removing the burner assembly bracket, and swapping the burner. Most DIY-capable homeowners complete this in 20–30 minutes. Always verify flame appearance after install and confirm no gas leaks.
