The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud precision-drilled for the Goodman GCH90905DXAB gas furnace. Each orifice meters the exact gas flow required for clean, efficient combustion at the rated BTU input — a critical safety and efficiency component of the burner assembly.
OEM Goodman orifices are drilled to a factory-verified diameter that matches the furnace's designed BTU rating and manifold pressure. Generic orifices may have inconsistent bore sizes, causing over- or under-firing, sooting, or nuisance lockouts. Because orifice sizing directly affects combustion safety, OEM is strongly recommended.
Moderate (2/5). Threads into the burner manifold with a wrench; verify manifold pressure after replacement. Shut off gas and power first, and confirm the correct orifice size for your altitude and fuel type.
