The 10716005 is a genuine OEM natural-gas burner orifice (spud) for the Amana/Goodman AMVC800603BXAA gas furnace. The orifice meters the precise volume of natural gas into each in-shot burner, setting the air-fuel ratio for clean, efficient combustion. A worn, enlarged, or debris-clogged orifice causes over/under-firing, sooting, poor flame color, and lost efficiency. Installing the correct OEM orifice restores rated BTU input and a proper blue flame.
The OEM orifice is bored to the exact drill size your furnace was certified for at its rated manifold pressure. Using a generic or wrong-size orifice changes the firing rate and can create dangerous over-firing or incomplete combustion. For safety and correct BTU input, OEM is essential — and never substitute an LP orifice for natural gas.
Rating: Moderate (3/5). Requires gas off, removing the manifold, and threading in the new orifice, then verifying manifold pressure and flame after install. Combustion adjustment should be confirmed by a licensed HVAC technician.
Tip: Replace as a full matched set for even firing across all burners. Verify your model and fuel type (natural gas vs. LP) before ordering.
