The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) precision-drilled for the GMH950453BXAD 95% AFUE gas furnace and other compatible Goodman and Amana models. The orifice meters the exact volume of natural gas delivered to each burner, ensuring the correct BTU input, clean combustion, and rated furnace efficiency.
Orifice sizing is critical to safe combustion. The OEM 10716003 is drilled to the exact factory specification for this furnace's manifold pressure and input rating. An incorrectly sized generic orifice can cause over-firing, sooting, delayed ignition, or carbon-monoxide risk. Always use the OEM-specified orifice and never redrill a spud in the field.
Moderate (3/5). Requires shutting off gas and power, removing the burner assembly, and threading the orifice to the manifold. Verify manifold pressure and check for gas leaks after installation. Professional HVAC service is strongly recommended for any gas-side work.
