MARS 12964 Run Capacitor

The MARS 12964 is a professional-grade 20/15 MFD 370V dual run capacitor designed for high-demand HVACR applications. This oval motor run capacitor provides a dual-capacitance solution, delivering 20 microfarads for the compressor and 15 microfarads for the fan motor in a single, space-efficient housing. Built for reliability in the field, it ensures stable voltage and current regulation for both starting and continuous operation. As a direct replacement for MARS 12064, this unit is engineered for compatibility with various condenser units and blower motors that require a 370VAC rating. The rugged, oil-filled design dissipates heat effectively, preventing premature failure in extreme ambient temperatures. For technicians performing preventative maintenance or emergency repairs, the MARS 12964 dual capacitor offers a precise microfarad tolerance, ensuring the motor operates at peak efficiency without excessive heat build-up or amperage draw. This HVAC dual run capacitor is an essential stock item for service trucks to restore system performance quickly and reliably.

• Dual-Action Performance: Simultaneously supports both the compressor (20 MFD) and the fan motor (15 MFD) using a single 370 VAC oval run capacitor.
• Enhanced Thermal Dissipation: The oil-filled oval metal case design efficiently manages internal heat for stable performance during high-load cycles.
• Broad Compatibility: Serves as a standard 20/15 microfarad capacitor replacement for numerous residential and light commercial HVAC brands.
• Compact Footprint: The oval profile is specifically designed to fit into tight electrical cabinets where round capacitors may not have sufficient clearance.

• Can I use a 440V capacitor to replace this 370V model? Yes, a higher voltage rating is acceptable as long as the microfarad (MFD) ratings match exactly (20/15 MFD).
• How do I know if my 20/15 MFD capacitor has failed? Look for signs such as a bulged or rusted top, or a motor that hums but fails to start. Testing with a multimeter for actual MFD output is the recommended professional method.
• Is the MARS 12964 an exact replacement for the MARS 12064? Yes, the 12964 is the current iteration designed to replace the legacy 12064 model with identical electrical specifications.
