The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM replacement component engineered for Goodman and Amana gas furnaces, including the AMEC800804CXAA model. This in-shot burner delivers a clean, stable flame that mixes gas and air efficiently before ignition inside the heat exchanger, ensuring reliable heating performance and safe combustion throughout the winter season.
Over time, burners can corrode, warp, or accumulate rust and debris that disrupt the flame pattern, leading to rough ignition, delayed lighting, or nuisance lockouts. Replacing a worn burner restores proper combustion and helps your furnace run at peak efficiency.
This is a genuine OEM burner built to exact factory tolerances, guaranteeing correct flame geometry and a precise fit into the burner rack. Generic aftermarket burners are typically 15–20% cheaper but may vary in port sizing and orifice alignment, which can cause uneven flame or reduced efficiency. For safety-critical combustion components, OEM is the recommended choice.
Moderate — Requires shutting off gas and power, removing the burner assembly, and swapping the burner. Best performed by an HVAC professional or an experienced DIYer familiar with gas furnace service.
