Overview

The Goodman B4022700 is a genuine OEM 3 inch in-shot burner built for the WFM18045S3AXCB furnace. In-shot burners inject a precise gas/air mixture into each heat-exchanger tube, where it ignites into a stable inner cone that transfers heat efficiently and burns cleanly. Over years of cycling, burners can rust, clog with scale, or develop erratic flames that cause delayed ignition, roll-out, or a flickering flame-sense signal. Replacing worn burners with the correct OEM part restores smooth light-off and even, quiet combustion across the burner rack.

Specifications

Type: in-shot (single-port) gas burner
Length: 3 in
Fits: Goodman WFM18045S3AXCB furnace
OEM part number: B4022700

OEM vs. Generic

The OEM Goodman burner is drilled and ported to the exact venturi geometry Goodman engineered for this furnace, so the flame profile and BTU delivery match spec. Generic burners may vary in port size and length, which can shift the air-fuel mixture and cause sooting or ignition faults. For safe, in-spec combustion, OEM is strongly recommended.

Install Difficulty

Moderate. Requires removing the burner assembly, transferring or replacing each burner, and verifying alignment with the igniter and flame sensor. Plan 30–45 minutes. Shut off gas and power first, and check flame quality after startup.
