Goodman a140 Draft Inducer Blower Motor 115V 1/50 Hp

Product Description

The GOODMAN a140 is a replacement draft inducer blower motor designed to restore proper flue gas exhaust in gas furnace systems. Rated at 1/50 horsepower and 115 volts, this shaded pole motor runs at 3400 RPM on a single speed, making it a direct-fit solution for residential heating equipment. The open enclosure and sleeve bearing construction are standard for inducer motor applications in ducted furnace assemblies. Licensed HVAC technicians install this type of motor as part of routine furnace maintenance or when diagnosing induced-draft failure codes. The Class B insulation rating and 40 degrees C temperature rating align with OEM specifications for the replaced units.

This motor fits ducted draft inducer assemblies in gas furnace systems where the original equipment used part numbers B2833001, 7021-9087, or 7021-9000. Draft inducer motors are typically found in mid-efficiency and some high-efficiency residential gas furnaces, positioned at the heat exchanger outlet to pull combustion gases through and exhaust them via the flue. This replacement is suited for service calls where the inducer motor has failed, seized, or is drawing excessive current. Installation requires matching the motor rotation, mounting configuration, and electrical connections to the original assembly.

Key Features

• Shaded pole motor design with single-speed operation at 3400 RPM
• 115-volt rating compatible with standard residential furnace control circuits
• Sleeve bearing construction appropriate for inducer blower duty cycles
• Open enclosure frame for heat dissipation in furnace cabinet environments
• Class B insulation rated to 40 degrees C ambient temperature
• Direct replacement for OEM part numbers B2833001, 7021-9087, and 7021-9000

Compatibility

Designed as a direct OEM-style replacement for Goodman draft inducer blower assemblies originally using part numbers B2833001, 7021-9087, or 7021-9000. Verify motor rotation, mounting orientation, and wiring configuration against the original unit before installation.

Installation Notes

Draft inducer motor replacement is performed by a licensed HVAC technician. Disconnect electrical power at the furnace disconnect and confirm the gas valve is closed before beginning any disassembly. The inducer housing and wheel must be inspected for debris or wear during the motor swap. Ensure the replacement motor shaft and mounting bracket align with the existing inducer housing before securing fasteners and reconnecting wiring.
