OEM Goodman 3" In-Shot Burner for AMH81005CNBB — B4022700

Goodman B4022700 In-Shot Burner (3")

Genuine OEM Goodman/Amana 3-inch in-shot burner, part B4022700. This is a direct-fit combustion burner for the AMH81005CNBB and many other Goodman, Amana, and Daikin 80%/90% gas furnaces. In-shot burners meter the gas/air mixture into the heat exchanger tubes; rusted, cracked, or clogged burners cause uneven flame, delayed ignition, roll-out, and sooting. Furnaces typically use one burner per heat-exchanger cell — replace as a matched set for best results.

OEM vs. Generic

The OEM burner matches the factory port pattern and length for correct flame carryover and heat-exchanger alignment. Our generic equivalent fits the same rack and orifice spacing and offers solid value when replacing a full burner set.

Install Difficulty: Moderate (3/5)

Shut off gas and power, remove the burner-assembly bracket, slide the old burner off its orifice, and align the replacement over the orifice into the heat-exchanger inlet. Verify flame carryover and check for proper ignition after reassembly. About 30–45 minutes for a full set.
