This OEM Goodman 10716005 natural gas orifice is a genuine precision-drilled burner spud for the Amana/Goodman AMH80803BNBC gas furnace. The orifice meters the exact volume of natural gas fed into each in-shot burner, setting the gas-air ratio that determines BTU input and flame quality. A worn, oversized, or debris-clogged orifice throws off firing rate, causing sooting, lazy flames, or insufficient heat.
Orifice bore diameter is calculated for this furnace's manifold pressure and rated input — even a few thousandths of an inch changes the firing rate. The OEM 10716005 is drilled to the factory specification for safe, efficient combustion. Generic or re-drilled orifices risk over- or under-firing the heat exchanger. Never substitute an LP orifice on a natural gas furnace; use the correct genuine part.
Roughly 20–30 minutes. Shut off gas and power, remove the burner panel, and unthread the old orifice from the manifold with a properly sized nut driver — avoid distorting the brass. Thread the new orifice in snugly without over-tightening, reassemble, and leak-check the manifold. Verify manifold pressure and clean blue flames on the next heat cycle.
