Description
The Mars 12739 is a 40/3 Microfarad, 370VAC round dual run capacitor engineered to deliver dependable starting and running performance for residential and light commercial HVAC systems. Dual run capacitors combine two capacitors in a single compact housing, simultaneously supporting both the compressor and the condenser fan motor — simplifying installation and reducing the number of components in the electrical panel.
Key Features
- Dual run capacitor rated at 40/3 Microfarad (MFD)
- Operating voltage: 370VAC
- Round housing for easy, space-saving installation
- Supports both compressor and condenser fan motor simultaneously
- Designed as a direct replacement for failed or degraded OEM capacitors
- Compact, round form factor fits most standard capacitor brackets
Applications
- Central air conditioning compressors
- Condenser fan motors
- Residential and light commercial HVAC equipment
- Heat pump systems
Why Replace Your Dual Run Capacitor?
A failing run capacitor is one of the most common causes of HVAC system problems, including hard starting, reduced efficiency, motor overheating, and complete system shutdown. Replacing a worn capacitor with a quality Mars unit restores proper motor operation, extends equipment life, and helps prevent costly compressor failures.
