The Goodman B4022700 3" In-Shot Burner is a genuine OEM combustion component for the Amana AMES800603BNAA gas furnace and compatible Goodman/Amana models. In-shot burners deliver a precisely shaped gas flame into each heat-exchanger tube for efficient, quiet, and complete combustion. Corroded, rusted, or clogged burners cause delayed ignition, roll-out, and uneven heating — replacing them restores clean, reliable ignition.
The OEM B4022700 is manufactured to the exact orifice alignment and flame geometry your furnace requires for a safe burn and proper flame-sensor rectification. Generic burners can misalign the flame, causing lazy ignition or nuisance lockouts. OEM ensures a factory-correct burn.
Moderate (2 of 5). Shut off gas and power, remove the burner-box cover, slide the old burner off the manifold orifice, seat the new burner, and reassemble. Replace all burners as a set for even performance — typically 20–40 minutes.
