The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the WGFM28090V5CXAB gas furnace. Each orifice meters the precise volume of natural gas delivered to a single burner, and its drilled bore size directly sets the furnace's BTU input. Using the correct OEM orifice keeps combustion clean, efficient, and within the manufacturer's rated firing rate — critical for safe heat exchanger operation and proper flame appearance.
Orifice sizing is unforgiving — a bore even a few thousandths off changes the firing rate and can cause sooting, delayed ignition, or over-firing. The OEM 10716003 is precision-drilled and thread-matched to the WGFM28090V5CXAB manifold, eliminating the guesswork and safety risk of a mismatched generic spud.
Rating: Easy–Moderate (2/5). Threads into the gas manifold and typically requires removing the burner assembly for access. Shut off gas and power first, and always leak-check with soap solution after reassembly. Note: never re-drill an orifice to change capacity — replace with the correctly sized part.
