The 10716003 is a genuine OEM Goodman natural gas burner orifice (spud) and a direct-fit replacement for the GKS90703BXAH gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and firing rate. A worn, corroded, or debris-clogged orifice produces weak, uneven, or sooty flames and can knock the furnace out of its rated input — making this an inexpensive but important part to keep in spec.
Orifice drill size directly controls the BTU input, so precision matters. The OEM 10716003 is drilled to the exact factory bore for the GKS90703BXAH at natural-gas pressures. A generic or mis-sized orifice can over- or under-fire the furnace, causing poor efficiency, sooting, or a safety hazard. OEM guarantees the correct bore and thread.
Moderate — gas work. Roughly 15–30 minutes: shut off gas and power, remove the manifold or burner as needed, unthread the old orifice, and install the new spud finger-tight plus a snug turn — do not over-torque brass. After reassembly, leak-test every joint with soap solution and confirm a clean blue flame. Because this involves the gas train, professional installation is strongly recommended.
Always shut off gas and power before servicing.
