Restore clean, even combustion to your Goodman/Amana AMH80803BXBB gas furnace with this genuine OEM B4022700 in-shot burner. Each in-shot burner directs the gas/air mixture into its heat-exchanger tube for ignition; a corroded, cracked, or clogged burner produces uneven flame, delayed ignition, sooting, or a rollout condition. Replacing a damaged burner — or the full set — brings the furnace back to a crisp, blue, well-seated flame.
Burner geometry controls how the flame seats in the heat exchanger. A generic burner with the wrong port size or throat length can shift the flame, causing noise, flashback, or premature heat-exchanger wear. The OEM B4022700 is dimensioned to Goodman's spec for correct flame position and safe, efficient firing. For best results, replace all burners as a matched set.
Shut off power and gas, remove the burner-box cover and igniter/flame-sensor as needed, slide the old burner off its manifold spud, and seat the replacement squarely on the same spud and locating tab. Typical time: 20–40 minutes for one, longer for a full set. If unsure, have a licensed technician verify flame and manifold pressure afterward.
