The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the Amana/Goodman AMH81155CXAA gas furnace. The orifice meters the precise volume of natural gas delivered to each in-shot burner, setting the furnace's firing rate and flame quality. A worn, corroded, or incorrectly sized orifice causes improper input, sooting, or lazy flames — this factory part restores exact metering.
Orifice sizing is critical to safe combustion and rated BTU input. This genuine OEM spud is drilled to the exact factory orifice size for the AMH81155CXAA. Using a generic or mis-drilled orifice can over- or under-fire the furnace. For gas metering, always use the correct OEM part.
Moderate — threads into the gas manifold; must be leak-checked after install. Replace as a matched set with other orifices. Recommended for a licensed technician. Shut off gas supply and power before servicing.
