The Goodman B4022700 3" In-Shot Burner is a genuine OEM single burner for the burner assembly on AMEH801005CXAB gas furnaces. In-shot burners direct the air/gas mixture straight into the heat exchanger tubes, where reliable, consistent ignition drives efficient heat transfer.
Rust, cracks, or a distorted flame pattern are signs a burner needs replacing. Installing the correct OEM in-shot burner restores a clean blue flame, proper flame-sensor rectification, and safe combustion.
OEM in-shot burners are engineered with the exact port geometry and orifice alignment for this furnace, ensuring proper flame carryover and combustion. Generic burners can misfire, cause delayed ignition, or fail flame sensing. For a combustion component, OEM is strongly recommended.
Moderate — requires shutting off gas and power, removing the burner assembly, and matching burner orientation to the orifice. Verify flame appearance and sensor current after installation. Best performed by a qualified HVAC technician.
