The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM brass spud for the AMS80704BXAA and compatible Goodman/Amana gas furnaces. Threaded into the burner manifold, it meters the exact volume of natural gas fed to each in-shot burner, establishing the furnace's rated BTU input and a stable, clean-burning flame.
Over time orifices can clog with debris or corrode, disrupting the fuel-air mixture and causing yellow flames, sooting, delayed ignition, or safety lockouts. Replacing a damaged or incorrectly sized orifice with the factory part restores correct firing rate and efficient, safe operation.
Because orifice bore size directly sets gas flow and combustion safety, genuine OEM is the recommended choice. Goodman machines this spud to the precise diameter its manifold pressure requires; generic substitutes may over- or under-fire the furnace. Do not attempt to enlarge or improvise an orifice.
Moderate (2/5). Turn off gas and power, remove the burner assembly for manifold access, and unthread the old orifice with a correctly sized socket, taking care not to damage the soft brass. Install the new spud, reassemble, and verify a clean blue flame on restart. Best handled by an experienced DIYer or licensed HVAC technician.
