The Goodman B4022700 is a factory OEM 3-inch in-shot burner engineered for Goodman and Amana 80% AFUE gas furnaces, including the AMH80804BXAA. Each in-shot burner mixes gas and primary air and directs the flame into the heat exchanger tube. Furnaces typically use one burner per heat-exchanger cell, so order the quantity that matches your model. Replacing corroded, rust-flaked, or misaligned burners restores a crisp blue flame, quiet ignition, and full rated heat output.
The genuine OEM B4022700 matches factory flame geometry and orifice alignment exactly, preventing flame rollout, delayed ignition, and sooting that generic burners can cause. Aftermarket burners may cost less but often require re-shimming and can trip the flame sensor or rollout switch.
Moderate (2/5). Requires shutting off gas and power, removing the burner assembly, and swapping the burner. Basic hand tools; 20–30 minutes. Always verify flame appearance and check for gas leaks after service. If unsure, hire a licensed HVAC technician.
