The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering spud for the GMH950703BXAD gas furnace and compatible Goodman 96% AFUE models. The orifice precisely regulates natural-gas flow into each burner, setting the furnace's rated BTU input and ensuring a clean, correctly proportioned flame. A worn, corroded, or incorrectly drilled orifice causes poor combustion, sooting, or off-rating heat output.
Orifice drill size directly sets the firing rate. The OEM 10716003 is machined to Goodman's exact bore diameter and thread spec for this model, guaranteeing correct BTU input and safe combustion. Generic or mislabeled orifices risk over- or under-firing the furnace — a safety and efficiency hazard. For a gas-metering component, always use the factory part.
Moderate (3/5). Requires shutting off the gas supply, removing the manifold or burner assembly, and threading in the new orifice, then leak-testing. Best performed by a qualified HVAC technician; verify manifold pressure and check for leaks after service.
