Keep your furnace burning clean and efficiently with the genuine Goodman B4022700 3-inch in-shot burner, a direct-fit replacement for the GDT115-5B gas furnace. Over time burners corrode, clog, or misalign, causing rough ignition, delayed light-off, and flame rollout. This factory burner restores a crisp, even flame and proper flame travel across the burner rack.
The OEM B4022700 is precision-formed to match Goodman's burner geometry and orifice alignment, ensuring correct gas-air mixing and a stable flame at the sensor. Generic burners can sit at the wrong depth or angle, leading to poor flame sensing and lockouts. For multi-burner furnaces, replace all burners as a set for even performance.
Easy to Intermediate. Shut off gas and power, remove the burner assembly, slide out the old burner, and seat the replacement. Verify flame sensor alignment on reassembly. Roughly 20–30 minutes.
