The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM replacement for the AMES800603AXAA gas furnace. This precision-drilled brass spud threads into the gas manifold and meters the exact fuel flow into each in-shot burner. Because orifice bore size sets the firing rate, a worn, damaged, or incorrectly sized orifice causes over- or under-firing, poor flame quality, sooting, and lost efficiency.
The genuine OEM orifice is drilled to the precise bore this furnace was certified with, guaranteeing the correct input BTU rating. Generic orifices may deviate in drill size, throwing off the firing rate and combustion. For gas-metering components, OEM sizing is essential to safe, code-compliant operation — confirm this is a natural gas (not LP) application before installing.
Easy to Moderate — unthread the old orifice from the manifold and thread in the replacement; match the count across all burners. 20–30 minutes. Shut off gas and power, then leak-test connections and verify the flame after installation.
