The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for the Amana/Goodman AMEH801005CXAA gas furnace. In-shot burners deliver a precise, consistent flame into each heat-exchanger tube for efficient, even heating. Rust, scale, or a distorted burner face causes rough ignition, flame roll-out, and reduced efficiency — making timely replacement important.
This OEM burner is manufactured to Goodman's exact orifice alignment and flame geometry for proper ignition carryover and safe combustion. Aftermarket burners can misalign with the orifice or heat exchanger, causing delayed ignition and roll-out. For a combustion component, OEM is the safe choice.
Moderate — Requires shutting off gas and power, removing the burner assembly, and verifying flame carryover and orifice alignment after install. Recommended for a qualified HVAC technician.
