The Goodman B4022700 3-Inch In-Shot Burner is a genuine OEM gas burner designed for Goodman ACVC801005CXAB and compatible high-efficiency gas furnaces. The in-shot design directs a focused, stable flame into the heat exchanger tube for clean, efficient combustion and even heat transfer across the furnace's firing rate.
Burners can corrode, clog, or distort from years of thermal cycling, causing rough ignition, flame rollout, or sooting. Installing a fresh OEM burner restores reliable lightoff and proper flame characteristics.
The OEM B4022700 matches Goodman's exact venturi geometry and mounting tab spacing, which is critical for correct air-fuel mixing and flame alignment with the igniter and flame sensor. Generic burners may differ slightly in port pattern and can cause delayed ignition or flame sensing faults. For safe, consistent combustion, OEM is strongly preferred.
Moderate (3/5). Replacement involves shutting off gas and power, removing the burner box or retaining bracket, swapping the burner, and verifying flame alignment and sensor position on restart. Best handled by an experienced DIYer or HVAC technician. Always confirm proper ignition and check for leaks after service.
