Trane BLW1138 1 Stage Inducer Draft Blower

As a seasoned tech, you know that a failing inducer is often the culprit behind pressure switch faults and ignition lockout. This Trane BLW1138 1 Stage Inducer Draft Blower is the direct OEM solution for maintaining precise negative pressure in your furnace's heat exchanger. Engineered as a high-performance replacement for the BLW0863, this assembly features a 115V single-phase motor running at approximately 3200 RPM. It utilizes a durable 3.3-inch frame and ball-bearing construction to ensure reliable venting of combustion byproducts through the flue. Whether you are servicing an American Standard blower motor assembly or a Trane high-efficiency unit, this genuine HVAC draft inducer replacement provides the exact physical fit and electrical parameters needed to restore quiet, efficient operation. Avoid the vibration issues and flange mismatches common with generic parts—this is the professional-grade Trane furnace part required for a clean, code-compliant install.

• OEM Precision: Direct replacement for BLW0863, BLW0518, and BLW0871 ensures mounting hole alignment and electrical connector compatibility.
• Rugged Build: Features a high-speed 3200 RPM motor with ball bearings designed for the high-heat environment of combustion venting.
• System Safety: Restores proper draft to satisfy pressure switches and prevent dangerous flue gas recirculation.
• Efficient Performance: 1.35 Amp draw at 115V provides optimal airflow with minimal power consumption for 1-stage heating systems.

Is this a direct replacement for the BLW0863?
Yes, the Trane BLW1138 is the factory-authorized superseding part for the BLW0863 and several other previous iterations, including BLW00863 and BLW0518.

Does this assembly include the motor and housing?
Yes, this is a complete 1 stage inducer draft blower assembly, including the motor, internal fan wheel, and the housing, ready for bolt-on installation.

How do I know if my inducer blower is failing?
Listen for "bird chirping" or grinding noises (bearing failure) or check for a 115V signal to the motor while the inducer fails to spin, often resulting in a pressure switch open error code.
