MARS 12769 Run Capacitor

The MARS 12769 Run Capacitor is a professional-grade 45/5 MFD 370VAC round dual run capacitor engineered for demanding HVACR applications. This dual-purpose component supports both the compressor and the condenser fan motor, ensuring synchronized starting and operational efficiency in residential and commercial condensing units. As a ruggedized 45/5 microfarad 370V dual capacitor, it serves as the direct replacement for D6789031 and the obsolete GE 97F9895 capacitor, providing a seamless field swap for technicians dealing with legacy equipment. Built to withstand high-duty cycles, this HVAC dual run capacitor features a non-PCB, oil-filled design with an internal pressure sensitive interrupter for hardware protection. Whether you are performing a seasonal tune-up or an emergency service call, the MARS 12769 delivers the high-capacitance stability required to maintain optimal motor torque and reduce amperage draw on the circuit.

Key Benefits:

• Universal Compatibility: Engineered as a high-spec 45/5 370V replacement for major OEM brands, including GE, Genteq, and Jard.
• Superior Heat Dissipation: The round aluminum casing is designed for maximum thermal conductivity, preventing premature failure in high-ambient rooftop or pad environments.
• High-Tolerance Engineering: Manufactured to strict industry standards to ensure precise microfarad output within +/- 5% of rated specifications.
• Secure Termination: Features standard 1/4-inch male quick-connect terminals for fast, reliable wiring in tight control boxes.

Common Questions:

Can I use a 440V capacitor to replace this 370V model?
Yes. While you should never undersize the voltage, a 440VAC capacitor can safely replace a 370VAC unit if the physical dimensions allow for a proper fit in the mounting strap. The 45/5 MFD rating must remain identical.

How do I identify the correct terminals on a dual run capacitor?
Most dual capacitors, including the MARS 12769, use standard labeling: "C" for Common, "HERM" for the compressor, and "FAN" for the condenser fan motor.

What are the signs that a 45/5 MFD capacitor has failed?
Common indicators include a domestic AC unit humming but not starting, a "bulged" or swollen top on the capacitor casing, or if a multimeter reading shows a capacitance drop of more than 5% or 10% from the nominal 45 or 5 MFD ratings.
