The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the Amana/Goodman AMH81155CNAB gas furnace. This small brass fitting meters the exact amount of gas delivered to each in-shot burner, setting the furnace's firing rate and BTU input. A worn, corroded, or incorrectly drilled orifice causes weak flames, poor efficiency, or over-firing — making the correct OEM spud essential for safe operation.
Orifice bore diameter directly determines BTU input, so precision matters. The OEM 10716003 is drilled to Goodman's certified specification for this furnace at its rated altitude. Generic or hand-drilled orifices risk incorrect gas flow, sooting, and unsafe combustion. Always match the OEM spud number.
Easy (2/5). The orifice threads into the manifold and is removed with a socket or wrench. Shut off gas and power first, verify the correct size, and leak-check all joints with soap solution after reassembly. When in doubt, consult a licensed technician.
