OEM Goodman 3 in. In-Shot Burner for AMES800804CXAA — B4022700

Goodman B4022700 3" In-Shot Burner

The B4022700 is a genuine OEM 3-inch in-shot burner for the Goodman/Amana AMES800804CXAA 80% AFUE gas furnace. In-shot burners inject a precisely shaped gas-and-air flame into each heat-exchanger tube for clean, efficient combustion. Rust, scale, or misfiring burners cause delayed ignition, poor flame carryover, and rollout — replacing worn burners restores smooth, safe lighting across the manifold.

OEM vs. Generic

The OEM B4022700 matches the factory burner-port geometry and manifold spacing, so the orifice alignment and flame pattern stay exactly as engineered — critical for proper flame sensing and clean burn. Generic burners can shift the flame position, trip the flame sensor, or seat poorly on the manifold. For safe, code-compliant combustion, install the OEM burner and replace as a matched set when possible.

Installation Difficulty

Moderate (3/5). Requires shutting off gas and power, removing the burner-box cover, disconnecting the manifold, and sliding burners off the manifold pins. About 30–45 minutes; verify flame pattern and check for leaks after reassembly. Professional installation recommended for gas components.
