The Lennox 23V84 ECM constant torque blower motor (catalog number 23V84, part number 624623-14) is a genuine OEM replacement motor designed for reliable airflow control in Lennox HVAC systems. This pre-programmed ECM motor delivers consistent torque and efficient performance while operating on 115V single-phase, 60 Hz power with a variable speed range of 0 to 1100 RPM.

This motor is rated at 1 HP and features a five-speed programmed ECM design, making it suitable for a wide range of residential and light commercial air handlers and furnaces. The motor uses a standard 48 frame with belly band mounting and is designed for horizontal installation. It includes a 1/2 inch by 3.92 inch shaft, counter-clockwise rotation (CCWLE), and durable ball bearings for long service life.

Important replacement information: Endura Pro constant torque motors are no longer manufactured by the original vendor. As a result, Lennox now supplies Ensite ECM motors as the official replacement. When replacing an Endura Pro motor, the replacement kit includes a programmed Ensite motor along with the required Ensite-to-Endura Pro adapter harness (107246-01), installation instructions, and zip ties. This adapter harness allows the Ensite motor to connect properly to systems originally designed for Endura Pro motors.

Endura Pro motors use a single large 9-pin connector, while Ensite motors use two smaller connectors: a 3-pin connector for line voltage power and a 6-pin connector for low-voltage speed taps. If the existing motor in the unit is an Endura Pro model, the adapter harness must be used. If the existing motor is already an Ensite motor, the adapter harness is not required.

This Lennox 23V84 motor replaces multiple earlier part numbers, including 81W41, 624531-14, 607363-10, and 607421-10, making it the latest approved OEM replacement in this motor family. Designed and approved by Lennox, this motor ensures proper compatibility, correct programming, and dependable operation when installed according to Lennox specifications.

This motor is sold as a complete OEM solution for restoring proper blower performance, airflow consistency, and system reliability in compatible Lennox HVAC equipment.
