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. Key Benefits 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. Common Questions 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.
