Description
The Lennox 72W39 is a round dual run capacitor rated at 75/10 microfarads and 440 volts AC, engineered to keep your air conditioning system running at peak efficiency. Dual run capacitors serve two motor circuits simultaneously — supporting both the compressor and the condenser fan motor from a single, compact component. This reduces wiring complexity and saves valuable space inside the unit cabinet.
Key Features
- Dual run capacitor supports compressor and condenser fan motor simultaneously
- 75/10 microfarad (MFD) dual capacitance rating
- 440VAC voltage rating for broad compatibility across residential and light commercial systems
- Round housing design for straightforward installation and secure mounting
- Genuine Lennox OEM replacement part (SKU: 72W39)
Why Dual Run Capacitors Matter
Run capacitors maintain a continuous phase shift in the motor windings to keep the motor running smoothly and efficiently after startup. A failing capacitor is one of the most common causes of compressor and fan motor problems, leading to hard starts, overheating, and premature motor failure. Replacing a worn capacitor with a properly rated OEM unit restores full motor performance and extends equipment life.
Application
- Designed as an OEM replacement for compatible Lennox air conditioning and heat pump systems
- Suitable for residential and light commercial HVAC applications
- Always verify system nameplate data and existing capacitor ratings before installation
