The 10716003 is a genuine OEM Goodman/Amana natural gas burner orifice (spud) for the AMH81005CXAA gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas into each in-shot burner, setting the furnace's firing rate and flame quality. A damaged, clogged, or incorrectly sized orifice can cause under- or over-firing, sooting, delayed ignition, or flame-sensor faults. This exact-fit OEM spud restores the factory-rated gas input for clean, efficient combustion.
The OEM 10716003 is drilled to the precise diameter Goodman specifies for this model's BTU rating and manifold pressure. Generic or mis-sized orifices change the firing rate, risking incomplete combustion, elevated CO, or a tripped limit. For a fuel-metering component, OEM is the safe, code-correct choice.
Easy (2/5). Shut off gas and power, thread out the old spud from the manifold, and install the replacement — do not over-tighten. Verify manifold pressure and flame after restart. Typically 15–20 minutes; combustion verification recommended for a professional.
Fitment guaranteed. Need LP orifices instead? Contact info@nationalhvacparts.com.
