The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered for the AMH80704BXCB gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, directly controlling the furnace's BTU input, flame quality, and combustion efficiency. Using the correctly drilled orifice is essential for safe, clean-burning operation and to avoid sooting, delayed ignition, or overheating.
The OEM 10716003 is drilled to Goodman's exact orifice diameter for this furnace's rated input. Generic orifices may have a slightly different bore, altering the gas rate and producing an improper flame. For combustion components, matching the OEM specification is critical for safety and warranty compliance.
Moderate (20–30 minutes). Shut off the gas supply and power. Remove the burner assembly or manifold, thread out the old orifice, and install the replacement — do not overtighten. Verify flame appearance and, ideally, check manifold pressure after install. Gas-line work should be performed by those comfortable working with gas connections.
