The Goodman B4022700 3-Inch In-Shot Burner is a genuine OEM combustion burner for the AMS80704BXA and related Goodman/Amana 80% AFUE gas furnaces. In-shot burners deliver the fuel-air mixture into each heat exchanger tube, producing the clean blue flame the furnace relies on for efficient, safe heating.

Burners can corrode, rust, or become clogged with lint and debris, which causes rough ignition, yellow or lazy flames, delayed light-off, and rumbling. A furnace uses one in-shot burner per heat exchanger cell, so replacing a damaged unit — or the full set — restores smooth, quiet ignition.

Specifications

OEM Part Number: B4022700
Part Type: In-shot (single-port) burner
Length: 3 inch
Fuel: Natural gas (convertible per furnace kit)
Material: Coated/aluminized steel
Compatible Model: AMS80704BXA

OEM vs. Generic

Genuine OEM burners are matched to the furnace's orifice size and manifold pressure, ensuring the correct flame profile and safe combustion. Off-brand burners may differ in port geometry, which can affect flame stability and trip the flame sensor or rollout switch. Because this part is combustion-critical, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Requires shutting off gas and power, removing the burner box, and carefully aligning the new burner with its orifice and igniter. After installation, verify a clean blue flame and proper flame-sensor reading. If you are not comfortable working with gas components, have a licensed HVAC technician perform the repair.
