The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component built for the Goodman GKS90904CXAE gas furnace. This precision-drilled brass orifice (spud) meters the exact volume of natural gas delivered to each burner, ensuring clean, efficient combustion and the correct BTU input rating. A clogged, corroded, or incorrectly sized orifice leads to poor flame quality, sooting, delayed ignition, or reduced heat output.
The OEM Goodman orifice is bored to the precise drill size specified for this furnace's rated BTU and gas type — a difference of one drill number changes the firing rate and can create unsafe combustion. Generic orifices may not match the exact bore, so we strongly recommend OEM for any gas-metering part.
Moderate (2/5) — Requires shutting off gas and power, removing the burner assembly, and threading in the new orifice with a nut driver. Recommended for experienced DIYers or an HVAC technician. Verify manifold pressure after install. Typical time: 20-30 minutes.
