The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GDT070-3 gas furnace. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner, controlling flame size, BTU input, and combustion efficiency. A damaged, clogged, or incorrectly drilled orifice can cause poor flame, sooting, delayed ignition, or unsafe combustion — making the exact factory orifice essential.
Because the orifice's drilled bore directly sets gas input, the genuine Goodman OEM part guarantees the correct, safety-tested metering for this furnace. Do not substitute a differently sized or field-drilled orifice — an incorrect bore alters BTU input and can create hazardous combustion. OEM only for this part.
Moderate — gas work. Replacement requires shutting off the gas, removing the burner/manifold access, and swapping the orifice, followed by a leak check and flame verification. Because gas is involved, we recommend a licensed HVAC professional.
