Lennox 19J24 – 35/5 MFD Dual Run Capacitor, 440V Round
The Lennox 19J24 is an OEM-grade dual run capacitor engineered to keep your air conditioning system running at peak efficiency. With a 35/5 MFD dual rating and a 440-volt design, this round capacitor supports both the compressor and the condenser fan motor from a single, compact component — simplifying installation and reducing the number of parts needed in the electrical panel.
Key Features
- Dual capacitance rating: 35 MFD (compressor) / 5 MFD (fan motor)
- Rated voltage: 440V AC
- Round form factor for easy drop-in replacement
- Supports simultaneous compressor and condenser fan motor operation
- OEM Lennox replacement part — SKU 19J24
- Designed for reliable, long-service-life performance in residential and light commercial HVAC applications
Why Dual Run Capacitors Matter
A failing run capacitor is one of the most common causes of air conditioner breakdowns. The dual run capacitor maintains the correct phase relationship between the run and start windings of both the compressor and fan motor, ensuring efficient motor operation, reduced energy consumption, and extended equipment life. Replacing a worn capacitor promptly prevents compressor damage and costly system failures.
Application
- Direct OEM replacement for compatible Lennox air conditioning systems
- Suitable for residential and light commercial split-system air conditioners and heat pumps
- Replaces dual run capacitors in condenser units requiring 35/5 MFD at 440V
