Goodman B4022700 3" In-Shot Burner

The B4022700 is a genuine Goodman 3-inch in-shot gas burner, a direct-fit replacement for the GMT045-3B and compatible Goodman/Amana furnaces. In-shot burners deliver the gas/air mixture into each heat-exchanger tube for clean, efficient combustion. Over time burners can rust, clog, or develop poor flame patterns that lead to delayed ignition, flame rollout, or sooting — replacing the affected burner(s) restores a crisp, blue flame and reliable light-off.

Specifications

Type: In-shot (single-port) gas burner
Length: 3 inches
Function: Delivers gas/air mix to one heat-exchanger tube
Fit: Direct OEM replacement for GMT045-3B
Brand: Goodman genuine OEM part

OEM vs. Generic

The genuine Goodman OEM burner matches the exact orifice alignment, venturi geometry, and flame characteristics this furnace was designed around. Generic burners can shift the flame pattern relative to the flame sensor and igniter, causing nuisance lockouts. Replacing all burners as a set with OEM parts gives the most consistent result. Sold individually.

Installation Difficulty

Easy–Moderate (2 of 5). Remove the burner assembly, slide out the old burner, and align the new one to the orifice and igniter. Shut off gas and power first; verify flame quality after install, or have a licensed HVAC technician perform the work.
