The Goodman B4022700 3-inch In-Shot Burner is a genuine OEM replacement designed for AMVC801005CNAB and compatible Goodman/Amana gas furnaces. This in-shot burner delivers the precise flame pattern the manufacturer engineered your furnace around, ensuring quiet ignition, clean combustion, and efficient heat transfer into the heat exchanger.
Over time, burners can accumulate rust, scale, or debris that distorts the flame and causes rough ignition, delayed lighting, or a loud whoosh on startup. Replacing a worn burner restores smooth, even firing and helps your furnace run at rated efficiency.
This is a genuine OEM burner, built to the exact port geometry and flame-retention spec of your furnace. Generic aftermarket burners may vary slightly in port size or seating, which can cause uneven flame or ignition problems. For a furnace, exact combustion geometry matters — we recommend OEM.
Easy to Moderate. Most DIYers can replace a burner in 20–30 minutes with basic hand tools. Always shut off gas and power first. If replacing one, inspect the full burner rack. When in doubt, use a licensed HVAC technician.
