The B4022700 In-Shot Burner is a genuine Goodman 3-inch gas burner engineered for the ADSS801005CXAC furnace and many other Goodman/Amana induced-draft furnaces. Multiple in-shot burners sit in a manifold row and fire directly into the heat exchanger tubes, mixing gas and air for efficient, stable combustion. Over time burners can corrode, rust, or clog with lint and scale, producing lazy yellow flames, delayed ignition, rollout, or sooting. Replacing worn burners restores clean blue-flame ignition and rated heating output.
The OEM Goodman B4022700 is stamped to the correct venturi geometry and port pattern for proper flame carryover and combustion calibration. Generic burners can alter the air/fuel mix, causing rough ignition or CO issues. OEM is strongly recommended for safe combustion.
Moderate (3/5). Requires shutting off gas and power, removing the burner assembly, and aligning the new burner to the manifold orifice. Best performed by an HVAC professional; verify flame and ignition after install.
