The 10716003 is a genuine OEM natural gas burner orifice (spud) for the Goodman/Amana AMH80903BNAB gas furnace. This precision-drilled brass jet threads into the manifold and meters the exact volume of natural gas delivered to each burner, setting the firing rate and ensuring clean, efficient combustion. A worn, corroded, or incorrectly sized orifice causes weak flames, sooting, delayed ignition, or an over/under-fired furnace. Each burner requires one orifice sized to the furnace's rated input.
The genuine OEM Goodman orifice is bored to the precise drill size your furnace's input rating and altitude derating require. Gas orifices are a life-safety and efficiency component — an aftermarket spud with the wrong bore can create dangerous over-firing, incomplete combustion, or carbon monoxide. Always match the exact OEM part for this application.
Rated Moderate (3/5). Shut off gas and power, disconnect the manifold, and thread out the old orifice with the correct wrench, then install the new spud snugly without over-torquing. Because this involves the gas supply, we recommend a licensed HVAC technician and a leak test with soap solution after reassembly.
Safety note: Never enlarge or modify an orifice. Verify manifold pressure and flame appearance after replacement.
