The Goodman B4022700 3" In-Shot Burner is a genuine OEM single-port burner for AMH80805CXBD and compatible Goodman/Amana 80% AFUE gas furnaces. In-shot burners deliver the gas/air mixture directly into the heat exchanger tubes for efficient, quiet, and stable ignition. Furnaces use one burner per heat-exchanger cell, so match your quantity to your BTU input rating.
Genuine OEM burners are stamped and drilled to factory tolerances, so the flame carryover ports, venturi throat, and mounting alignment match the heat exchanger exactly. Generic burners can shift flame pattern or create rollout — not worth the risk on a combustion component. We recommend OEM here.
Moderate (3/5). Requires shutting off gas and power, removing the burner assembly bracket, and sliding the burner off its manifold orifice. Verify flame seating and check for rollout after reassembly. Best handled by an experienced DIYer or licensed HVAC tech. Approx. 30–45 minutes.
Compatible with Goodman and Amana furnaces. Confirm burner count and fuel type before ordering.
