The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM gas burner engineered for the Goodman/Amana ADVC81005CNBA furnace and compatible models. In-shot burners deliver a precisely shaped gas/air stream into each heat-exchanger tube for clean, efficient, and stable combustion. Over time, burners accumulate rust, scale, and debris that distort the flame pattern and cause rough ignition or delayed light-off; installing fresh OEM burners restores crisp, blue-flame ignition and rated furnace efficiency.
The OEM B4022700 is manufactured to the exact port geometry and orifice alignment this furnace was certified with. Generic burners can alter the flame carryover and air/fuel ratio, leading to sooting, noise, or safety-related flame-sense issues. OEM keeps combustion within factory spec.
Moderate (3/5). Budget 30–60 minutes to replace a full burner set. Gas must be shut off and the burner assembly removed; replace all burners together for an even flame pattern and verify proper seating and cross-lighting on start-up. Because this involves the gas train, a licensed HVAC technician is recommended.
