Trane BLW1334 Blower

The Trane BLW1334 is a dual-stage inducer blower assembly designed for high-efficiency gas furnaces. This centrifugal draft inducer is critical for maintaining correct static pressure and ensuring proper combustion byproduct venting. Operating on 115V, this 2-speed blower motor utilizes a precision-balanced wheel to minimize harmonic vibration and prevent premature bearing failure. As a direct OEM replacement part, it ensures seamless integration with the existing furnace control board and pressure switches. Field technicians frequently rely on the BLW01334 to resolve inducer motor noise or 102 fault codes associated with RPM fluctuations. The assembly includes the motor and blower housing, allowing for a standard bolt-on installation. Proper draft inducer performance is essential for secondary heat exchanger longevity, making this high-output blower a staple for Trane furnace repair and seasonal maintenance cycles.

• Optimized Airflow: Engineered for two-stage heating systems to provide precise CFM delivery during low and high fire modes.
• Direct Fit Compatibility: Eliminates the need for field modifications, ensuring OEM specifications for flange alignment and wiring harnesses are met.
• Enhanced Durability: Constructed with high-temperature grade materials to withstand corrosive flue gases and thermal cycling.
• Reduced Operational Noise: Dynamically balanced impeller wheel lowers decibel levels during the pre-purge and post-purge cycles.

Common Questions

Is the BLW1334 compatible with single-stage furnaces?
No, this is a 2-speed inducer motor specifically designed for multi-stage gas valves. Using this on a single-stage system will result in communication errors with the integrated furnace control.

Does this assembly include the pressure switch?
This product is the inducer blower motor and housing assembly. Existing pressure switches should be inspected for calibration and moved to the new housing or replaced separately if they fail to close.

What are the symptoms of a failing Trane inducer blower?
Watch for bearing seized warnings, high-pitched screeching during the start-up sequence, or the furnace failing to ignite due to the pressure switch not detecting sufficient vacuum.
