The genuine Goodman B4022700 3-Inch In-Shot Burner is a factory replacement burner for the AMVC800603BXAA variable-speed 80% gas furnace. In-shot burners direct the gas/air mixture into the heat exchanger tubes for clean, efficient combustion. Over time, burners can rust, clog with debris, or develop misaligned flames that cause delayed ignition, sooting, or short cycling. Installing a fresh OEM burner restores crisp ignition and even, blue-flame combustion across the manifold.
This genuine Goodman OEM burner matches the original venturi geometry and mounting slot for correct flame projection into the heat exchanger. Generic burners can alter the air-fuel mixture, producing lifting or rollout flames that trip the flame sensor and rollout switch. For safe, code-compliant combustion, the OEM in-shot burner is the reliable choice. Replace all burners as a set for uniform flame characteristics.
Moderate. Requires shutting off gas and power, removing the burner box/manifold, and sliding the burner off the orifice rail. Roughly 30–60 minutes with hand tools. Because this is a combustion component, a licensed HVAC technician should verify flame, ignition, and gas pressure after installation.
