Lennox 98M39 Motor

The Lennox 98M39 ECM Condenser Fan Motor (Model #100016-02) is a high-efficiency OEM replacement motor manufactured by Regal Beloit for Lennox, Armstrong, and Ducane equipment. This 1/3 HP variable speed motor operates at 208-230V and is designed for NEMA 48-frame applications, specifically within high-performance Lennox XC21, XP17N, XP19, XP21, and XPG20 condensing units. As an electronically commutated motor, it features an integrated control module—non-serviceable once failed—to manage airflow precisely between 0 and 820 RPM, optimizing head pressure and increasing seasonal energy efficiency ratings.

For field replacement, this motor features a 1/2-inch by 3.92-inch shaft and is intended for vertical mounting with its ball bearing system support. The rotation is CCW from lead end (CCWLE), and it includes electronic protection to safeguard the internal windings against common voltage fluctuations. This unit directly replaces older Lennox 85M48 and 100016-01 part numbers, ensuring a drop-in installation for veteran technicians servicing premium residential and light commercial heat pumps.

Key Benefits for Contractors:

• Direct OEM Integration: Built by Regal Beloit specifically for Lennox, eliminating the need for mounting bracket modifications or wiring harnesses often required with universal ECMs.
• Enhanced Durability: Equipped with ball bearings and Class B insulation rated for continuous air-over duty in harsh outdoor environments.
• Precision Performance: The integrated control module dictates specific ramping profiles to match original system specifications for noise reduction and cooling efficiency.
• Simplified Maintenance: Replaces 100016-01 and 85M48, providing a standardized part for multiple generations of XC and XP series air conditioners.

Common Questions:

Is the control module available separately?
No, the Lennox 98M39 comes with the control module permanently factory-installed at the end of the motor; it is not sold as a separate component.

What is the correct rotation for this motor?
This ECM condenser fan motor is balanced for CCW rotation when viewed from the lead end (CCWLE).

Can this be used in 460V applications?
No, this motor is strictly rated for 208-230V single-phase 60Hz power supplies. Using higher voltage will result in immediate module failure.
