The Goodman B4022700 is a genuine OEM 3-inch in-shot burner built for VMES800805CXAA gas furnaces and compatible Goodman/Amana models. Each in-shot burner directs a precise gas/air mixture into the heat exchanger tube for clean, efficient, and reliable ignition across the burner array.
This genuine OEM Goodman burner is manufactured to the exact orifice alignment and venturi dimensions your furnace was engineered around. Aftermarket burners can alter the flame pattern, cause flame rollout, or produce incomplete combustion. For safe, spec-correct heating, the OEM burner is strongly recommended.
Replace burners that are rusted, cracked, or clogged, or if you experience a lazy/yellow flame, delayed ignition, or noticeable flame rollout. Replacing the full set is best practice when one has failed.
Moderate (3/5). Requires shutting off gas and power, removing the burner assembly, and aligning the new burner to the orifice and flame sensor. Budget 30–45 minutes. If you're not confident working with gas components, use a licensed HVAC technician.
