Trane BLW1137 Draft Blower

The Trane BLW1137 is a genuine OEM 1-stage induced draft blower assembly engineered for high-performance combustion air management in residential and light commercial furnaces. This critical component is the direct replacement for legacy part numbers BLW0862 and D342094P01. As a 1-stage induced draft blower, it functions by creating a controlled vacuum to pull combustion gases through the heat exchanger and expel them safely via the flue vent. This process ensures the pressure switch closes, allowing the furnace to initiate the ignition sequence reliably.

Constructed for high-heat environments, the BLW01137 assembly features a robust housing and a balanced impeller to minimize vibration and bearing wear. When performing a furnace draft inducer motor replacement, using an OEM Trane draft blower ensures the proper CFM and static pressure requirements are met, maintaining the system's combustion integrity and HVAC efficiency. This assembly is designed for exact fitment, reducing field modification time for service technicians and ensuring compatible electrical connectors for standard 115V or specified furnace control boards.

Key Contractor Benefits:

• Direct OEM Fit: Eliminates the need for mounting adjustments or wiring modifications common with universal aftermarket blowers.
• High-Temperature Durability: Engineered with furnace-grade materials to prevent housing warping and premature motor failure.
• Combustion Safety: Provides the precise static pressure required to actuate the pressure switch and prevent dangerous flue gas recirculation.
• Optimized Performance: Maintains the original factory SEER and AFUE ratings by ensuring proper air-to-fuel ratios during the burn cycle.

Common Questions:

Is the BLW1137 compatible with my furnace if my old part is BLW0862?
Yes, the BLW1137 is the official Trane direct replacement for part numbers BLW0862 and D342094P01. It utilizes the same mounting pattern and electrical specifications.

What are the signs that a draft blower needs replacement?
Common indicators include excessive bearing noise (grinding or screeching), a "failed pressure switch" error code on the control board, or the blower failing to spin up despite receiving the correct voltage from the furnace.

Does this assembly include the necessary gaskets?
Most Trane furnace inducer motor assemblies are designed for use with specific high-temp gaskets or silicone sealants to prevent carbon monoxide leaks. Check the existing housing interface during installation.
