Lennox 23V89 Motor

The Lennox 23V89 Motor Replacement Kit, part number 607421-31, is a pre-programmed ECM constant-torque blower motor designed for compatible Lennox furnace and HVAC blower applications. The motor is rated at 1/2 HP, 115 VAC, single phase, 60 Hz, with five speeds and an operating range of approximately 550–1300 RPM.

The programmed ECM design provides the operating characteristics required for specific Lennox equipment applications. This motor uses a 48 frame, horizontal mounting position with belly-band mounting, ball bearings, and CCWLE rotation. The shaft measures approximately 1/2 inch x 4.5 inches.

Because the 607421-31 is a programmed motor, contractors should verify the complete furnace model and serial number before replacement rather than matching horsepower and voltage alone. Confirm the original motor number, programming, mounting configuration, rotation, shaft dimensions, electrical requirements, and blower application before installation.
