The Goodman B4022700 is a genuine OEM 3-inch in-shot gas burner built for the ADSS800603AXAD furnace and compatible Goodman/Amana models. Each in-shot burner directs the gas/air mixture into a heat exchanger tube for smooth, quiet ignition and even flame distribution. Replacing burnt, rusted, or clogged burners restores clean combustion and prevents delayed ignition and rumbling.
The OEM Goodman B4022700 is stamped and slotted to factory spec so the flame carries correctly across the burner rack and lights reliably from the igniter. Generic substitutes frequently mismatch the venturi or port pattern, causing rough ignition, flame roll-out, or nuisance flame-sensor lockouts. For a combustion component, OEM accuracy matters.
Moderate (2/5). Shut off gas and power. Remove the burner assembly access, slide the old burner off its mounting slot, and seat the new B4022700 in the same position aligned to the igniter and flame sensor. Confirm flame appearance and cycle the furnace after install. Order one burner per tube for a full set.
Compatible with Goodman ADSS800603AXAD furnaces. Genuine OEM part with fast shipping.
