The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMEC960403ANAA gas furnace and compatible Goodman/Amana models. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's rated BTU input. Correct orifice sizing is critical: too large over-fires the furnace (sooting, overheating, high-limit trips), while too small starves the burners and drops heating capacity.
Orifice bore diameter is machined to a tolerance measured in thousandths of an inch, and that bore determines gas flow and combustion quality. The OEM Goodman 10716005 is drilled to the exact factory specification for this furnace and altitude rating. Generic or mis-marked orifices can shift the BTU input outside safe combustion limits. Always match OEM for correct, safe firing.
Moderate (3/5). Turn off gas and power. Remove the burner assembly to access the manifold, thread out the old orifice, and install the new spud with the correct torque — do not overtighten brass threads. A gas-leak (bubble) test and combustion check are required after service. Best performed by a qualified technician; typical time 30–45 minutes.
Keep your furnace firing to spec with the genuine Goodman 10716005 natural gas orifice.
