Amana-Goodman B2589342 Orifice

Maintain peak combustion efficiency with the Amana-Goodman B2589342 Orifice, a high-precision #42 burner orifice designed for specific gas furnace manifolds. This genuine HVAC OEM replacement part is critical for regulating the manifold pressure and gas flow rate across the burner assembly. As a veteran-grade component, the B2589342 is engineered for a perfect fit in Amana and Goodman gas furnaces, ensuring the correct BTU output and preventing soot accumulation or delayed ignition caused by improper fuel-to-air ratios. This brass gas orifice features a standard #42 drill size, providing the durability needed to withstand high-temperature environments without corroding or losing its calibrated diameter. Whether you are performing a seasonal tune-up or a corrective furnace burner repair, using this factory-spec heating system component ensures the appliance operates within its original safety parameters. Always verify the heating capacity and altitude requirements to ensure a #42 orifice meets the specific manifold pressure specs for your installation site.

• Precise Gas Regulation: Calibrated #42 drill size ensures consistent fuel delivery to the burner for stable flame patterns.
• OEM Compatibility: Specifically designed for Goodman and Amana furnace manifolds, including GMP, GMPE, and GPD series units.
• Durable Construction: High-grade brass material resists corrosion and thermal expansion, maintaining the integrity of the orifice diameter.
• Combustion Optimization: Helps prevent common issues like "lazy flames" or excessive carbon monoxide production by maintaining the correct gas velocity.

• Which furnace models use the B2589342 orifice? This part is primarily used in Goodman GMP, GMPH, and PGB series furnaces. Always check your specific model’s parts list to confirm it requires a #42 orifice.
• Can this be used for LP (Propane) conversions? Orifice sizing is fuel-specific. A #42 drill size typically corresponds to Natural Gas; always refer to the manufacturer’s conversion kit instructions for Propane (LP) sizing.
• How do I know if my orifice needs replacing? Clogged or damaged orifices can cause uneven heating or burner failure. If the orifice is corroded or the opening is enlarged from improper cleaning, it must be replaced.
