The Goodman B4022700 3-Inch In-Shot Burner is a genuine OEM replacement for the Goodman/Amana ADVC81005CXAA gas furnace. Each in-shot burner mixes gas and primary air and directs a stable flame into the heat exchanger tube. Over time burners can rust, distort, or develop a rough or lifting flame — replacing the affected burner restores clean, quiet, efficient ignition.
OEM in-shot burners are dimensionally matched to the manifold spud spacing and heat-exchanger port on your furnace, ensuring correct flame carry-over and combustion. Generic burners can alter the air-fuel mixture, cause delayed ignition, sooting, or flame roll-out. For a safe, code-compliant repair, factory-original Goodman burners are the recommended choice.
Moderate (3/5). Replacement requires shutting off gas and power, removing the burner box or bracket, and reseating the burner over the manifold orifice with correct alignment. Recommended for HVAC technicians. Verify flame carry-over and inspect for roll-out after service. Replace all burners as a set if others show wear.
Fits Goodman and Amana ADVC81005CXAA furnaces. Confirm burner count and quantity needed for your unit before ordering.
