The B4022700 is a genuine OEM 3-inch in-shot burner for Goodman ADSH800603AXAC gas furnaces and compatible models. Each in-shot burner directs a precise gas/air mixture into its heat-exchanger tube for clean, efficient combustion. Furnaces of this class use one burner per exchanger cell, so worn, rusted, or sooted burners cause uneven flame, delayed ignition, and reduced heating output — replace as a matched set for best results.
The OEM Goodman burner is stamped to the exact orifice alignment and venturi geometry this furnace is tuned for, delivering the correct flame pattern and manifold pressure. Generic burners can misalign with the flame sensor and igniter, causing rollout or flame-sense faults. We recommend OEM for reliable ignition.
Rated 3/5. Requires removing the burner assembly and aligning each burner to its orifice and heat-exchanger tube. Shut off gas and power, replace burners as a set, and verify flame color and ignition after service. If unsure, use a licensed HVAC technician.
