The Trane KIT2588 Combustion Blower Kit is a critical OEM replacement assembly designed for 80-135 MBH gas furnaces. Engineered as a high-performance draft inducer motor, this kit ensures the precise extraction of flue gases through the heat exchanger, maintaining the pressure switch circuit and preventing ignition failure. This comprehensive furnace inducer blower assembly replaces legacy part numbers including KIT02588, FAN01890, and FAN02162. Operating at a nominal 3500 RPM, the motor is specifically calibrated to handle the static pressure requirements of Trane and American Standard residential units. The kit provides a complete mechanical solution, featuring the centrifugal blower housing, inducer motor, integrated sight glass, and the necessary gaskets to ensure a gas-tight seal upon installation. For technicians troubleshooting noisy bearings or high-limit trips, this combustion blower assembly restores factory-spec airflow and combustion efficiency without the need for field modifications or bracket fabrication. Key Benefits Direct OEM Compatibility: Ensures exact fitment for Trane and American Standard 80-135 MBH furnaces, eliminating the need for universal motor adapters. Complete Installation Package: Includes the combustion fan, motor, motor-to-housing gaskets, and sight glass for a comprehensive professional repair. Specific RPM Calibration: Fixed 3500 RPM operation provides the consistent negative pressure required to close the furnace pressure switch. Durable Construction: Built to withstand high-temperature flue gas environments, preventing housing warping and premature motor failure. Common Questions Is the KIT2588 a direct replacement for my older FAN01890 motor? Yes, the Trane KIT2588 is the current manufacturer-designated replacement for many legacy part numbers, including FAN01890 and KIT02588. It provides the same mounting footprint and electrical specifications. Does this kit include the gasket required for the transition to the flue pipe? The kit includes the internal gaskets for the blower assembly; however, we recommend verifying the condition of the collector box gasket during installation to ensure a total exhaust seal. How do I confirm if this inducer motor matches my furnace tonnage? This kit is specifically designed for furnaces in the 80 to 135 MBH range. Check your furnace data plate for the BTU rating and cross-reference with the KIT2588 specifications before field installation. This item is not eligible for free shipping.
