The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner orifice (spud) for the Amana/Goodman AMVC951155DXBA gas furnace. The orifice meters the exact volume of natural gas delivered into each burner, setting the input rate and ensuring a clean, blue, correctly-sized flame. A worn, corroded, or wrong-size orifice causes poor combustion, sooting, delayed ignition, or an out-of-spec input rate. Using the factory-drilled orifice keeps the furnace firing at its rated BTU input for safe, efficient heating.
Orifice sizing is safety-critical. The OEM 10716003 is precision-drilled to the exact diameter Goodman specifies for this furnace's manifold pressure and BTU rating. Generic or mismatched orifices can over- or under-fire the unit, producing carbon monoxide or nuisance lockouts. OEM guarantees the correct bore, thread, and seat.
Moderate (2/5). Shut off gas and power, back out the old orifice from the manifold with a nut driver, thread in the OEM replacement, and leak-check with soap solution before relighting. About 15–20 minutes. Gas work should be performed by a qualified technician where required by local code.
