The Goodman B4022700 3-Inch In-Shot Burner is a genuine OEM replacement burner for the AMH81155CNAB gas furnace and compatible Goodman/Amana 80% AFUE models. In-shot burners deliver the gas/air mixture into the heat exchanger tubes for smooth, quiet, and efficient ignition. Replace a rusted, sooted, or misfiring burner to restore reliable heat and safe combustion.
This OEM Goodman burner is manufactured to the precise venturi and port geometry your furnace was calibrated for, ensuring correct flame carryover and gas-valve pressure matching. Generic burners can alter the flame pattern, causing flame roll-out, delayed ignition, or lazy yellow flames. For a combustion-critical component, OEM is strongly recommended.
Moderate (2/5). Shut off gas and power, remove the burner-box cover, slide the old burner off its mounting bracket, and seat the replacement so it aligns with the heat-exchanger inlet and igniter. Burners are usually replaced as a matched set — order one per tube. Test for proper flame after install.
All parts are sold new. Verify your model and serial number before ordering.
