The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component for the Goodman GCH950453BXAB gas furnace and compatible models. This precisely machined orifice (spud) meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and correct BTU output. A worn, corroded, or incorrectly drilled orifice can cause poor combustion, sooting, or inefficient heating — restoring the factory orifice returns the furnace to spec.
Orifice drill size directly controls gas flow and BTU input. The OEM Goodman orifice is bored to the manufacturer's exact specification. Generic or mis-sized orifices risk over- or under-firing the furnace, which can damage the heat exchanger or produce dangerous combustion. Always use the correct OEM part for the fuel type.
Difficulty: Moderate (3/5). Requires removing the burner assembly and threading the orifice to spec. Shut off gas and power first. Because this involves the gas train, we recommend a licensed HVAC technician verify manifold pressure after installation.
