Application
The Lennox 89M89 is ideal for use as a direct OEM replacement in Lennox air conditioning and heat pump systems. Run capacitors are critical components that maintain a continuous phase shift in the motor windings, enabling smooth, efficient motor operation. A failing run capacitor is one of the most common causes of compressor and fan motor failure — replacing it promptly with a quality OEM part like the 89M89 protects your investment and restores system performance.
Installation Notes
- Always discharge the capacitor before handling
- Match terminal labels (HERM, FAN, COM) carefully during installation
- Verify voltage and MFD ratings match the original capacitor before installation
- Consult equipment documentation or a qualified HVAC technician for proper installation procedures
