Amana-Goodman B4059000S Inducer Motor Assembly

The Amana-Goodman B4059000S Inducer Motor Assembly is a critical OEM replacement component designed for high-efficiency draft induction in residential furnaces. This assembly, which serves as the direct cross of 66590, features a high-performance 115V draft inducer motor operating at 3000 RPM with a 1.4 to 1.5 FLA rating. Engineered for precise compatibility with units such as the GMT, GDT, and GPD series, the B4059000S ensures the vent system maintains the necessary static pressure for safe combustion gas transition. The motor utilizes a ball bearing design and Class B insulation for thermal protection and consistent cooling undercover air-over conditions. This furnace vent blower motor is built with a sturdy metal housing to withstand the demanding duty cycles of modern HVAC systems. When replacing a failed draft inducer assembly, this 1/35 HP unit provides the exact CWLE rotation and fitment required to restore sequence of operation and prevent pressure switch trip-outs.

• OEM Compatibility: Exact replacement for Goodman furnace inducer motors and Amana draft blowers, ensuring no-drill installation.
• Enhanced Durability: Equipped with precision ball bearings to reduce mechanical friction and extend the service life of the draft inducer assembly.
• Safety Compliance: Features internal thermal protection to prevent motor burnout during restricted vent or high-heat conditions.
• Drop-in Replacement: Directly replaces multiple part numbers, including 66590, 7002-3036, and J238-112-11258.

Is the mounting gasket included with this inducer assembly?
Yes, the B4059000S typically includes the necessary gasket to ensure a combustion-tight seal against the collector box.

Will this motor fix my furnace if it is stuck on a pressure switch error?
If your draft inducer blower is seized or failing to reach 3000 RPM, it will not create enough vacuum to close the pressure switch; replacing the assembly is the standard solution.

Can I use this to replace a Fasco or Jakel motor in my furnace?
As long as your original part crosses to B4059000S or 66590, this OEM assembly is the correct technical replacement regardless of the original motor manufacturer.
