The Goodman/Amana 10716005 Natural Gas Orifice (spud) is a genuine OEM burner component for the AMEC801005CNAA gas furnace and compatible Goodman and Amana models. The orifice threads into the manifold and precisely meters the flow of natural gas into each burner. Its factory-drilled bore diameter sets the furnace's BTU input, so using the correct orifice is essential for clean combustion, proper flame appearance, and safe, efficient heating.
OEM vs. Generic: Orifice bore size is measured in thousandths of an inch, and the genuine OEM 10716005 is drilled to the exact specification for your furnace's rated input. A generic orifice with even a slightly different bore can over- or under-fire the burner, causing sooting, delayed ignition, or a safety lockout. For a combustion component, always match the OEM part.
Install difficulty: Moderate (3/5). Shut off gas and power, remove the burner assembly or manifold as needed, unthread the old orifice, and thread in the replacement (do not overtighten — brass threads strip easily). After installation, verify flame quality and check for leaks with a soap solution. Gas work should be performed by a qualified technician where required by local code.
