Lennox 40C98 Motor

When replacing a critical condenser fan motor on Lennox CHA series and similar commercial units, the Lennox 40C98 is the technician's choice for a direct-fit OEM solution. This 1/2 HP motor is engineered for high-voltage 460V single-phase applications, delivering a steady 1075 RPM to maintain optimal head pressure and heat dissipation across the condenser coils. Built on a standard 48 frame with a belly band mount design, it facilitates a clean, vertical installation in demanding rooftop or ground-level environments. The ball bearing construction ensures lower friction and extended run-times in high-ambient conditions, while the CCW rotation (lead end) matches the original factory fan blade pitch to maintain specified CFM. For optimal performance and motor longevity, always verify the 12.5 MFD 370 VAC capacitor during installation to ensure proper torque and amperage draw.

• Direct OEM replacement motor ensures exact physical dimensions and electrical compatibility without mounting modifications.
• Designed for 460V 1-phase power supplies common in commercial HVACR systems.
• High-grade ball bearings support vertical shaft-up or shaft-down orientations while resisting environmental contaminants.
• The 1/2 inch diameter by 4 inch shaft provides a secure mate for standard blower wheels and fan blades.

What is the correct capacitor for the Lennox 40C98?
This motor requires a 12.5 MFD 370V capacitor for proper starting and running performance. Using a mismatched capacitor can lead to overheating or premature winding failure.

Can I use this motor to replace a 230V model?
No. The Lennox 40C98 is specifically wound for 460V. Applying 230V will result in insufficient torque and motor stall, while higher voltages will destroy the internal insulation.

Does this motor include the mounting bracket?
This is a 48 frame motor intended for belly band mounting. The existing bracket should be reused, or a compatible 48-frame band must be sourced separately.
