The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for the Amana/Goodman AMEH800805CXAA gas furnace. Each in-shot burner delivers a precisely shaped gas/air flame into its corresponding heat-exchanger tube for efficient, complete combustion. Rust, cracking, or a distorted flame pattern are signs a burner should be replaced to restore clean ignition and even heating.
A genuine OEM Goodman in-shot burner is dimensioned and ported to match the furnace's orifice size and heat-exchanger geometry, ensuring the correct flame length and stable ignition. Generic burners can misfire, cause flame rollout, or trip the flame sensor. Combustion components should always be OEM.
Moderate. Requires gas shutoff, removal of the manifold, and correct burner alignment to the orifice and igniter. Recommended for a licensed HVAC technician; verify flame quality and leak-test after installation. When replacing one burner, inspect the full set.
Confirm the part number and burner length before ordering.
