The Goodman 0163F00018 Natural Gas Orifice is a genuine OEM burner spud that meters the precise volume of natural gas into each burner of the AMVC80604BNAA furnace and other compatible Goodman/Amana models. The drilled orifice size is matched to the furnace's input rating and manifold pressure for clean, efficient, and safe combustion.
Orifice drill size directly controls the BTU input to each burner. The genuine OEM 0163F00018 is bored to the factory specification for this furnace, so flame quality and input stay within rating. An incorrect generic orifice can cause overfiring, sooting, or CO production—use OEM.
Easy (2/5). Threads into the manifold after removing the burner. Turn off gas and power, and leak-check all connections with soap solution on restart. Confirm flame appearance and, ideally, manifold pressure with a licensed technician.
