MARS 12084 Run Capacitor

MARS 12084 Run Capacitor

The MARS 12084 Run Capacitor is a high-performance 75/10 microfarad 370Vac round dual run capacitor engineered for continuous duty in residential and light commercial HVACR systems. Designed to support both the compressor and the condenser fan motor, this dual run capacitor ensures optimal phase shift and torque for permanent split capacitor (PSC) motors. Built with a hermetically sealed aluminum case and a physical pressure interrupter, it provides reliable protection against internal pressure buildup, securing the electrical circuit during peak thermal loads. With a temperature rating of -40°C to +70°C and a 60,000-hour operational life, the MARS 12084 meets EIA-456-A standards and is UL and CUL recognized. This OEM-grade component is a critical HVAC replacement part for technicians troubleshooting humming compressors or failed fan startups, offering the precise capacitance required to maintain energy efficiency and motor longevity in demanding environments.

Key Benefits
  • Dual Capacitance Design: Combined 75 MFD (Herm) and 10 MFD (Fan) ratings allow for a single-component solution in outdoor condensing units.
  • Enhanced Safety: Features a physical interrupter and non-PCB oil-free construction for safe failure modes and vibration resistance.
  • Industrial Durability: Engineered with metallized polypropylene film and housed in a corrosion-resistant aluminum canister.
  • Precise Tolerance: Maintains electrical stability within narrow tolerances to prevent motor overheating and premature winding failure.
  • Universal Round Profile: Standard dimensions ensure compatibility with existing mounting straps in most HVAC cabinets.
Common Questions

How do I identify the terminals on this capacitor?
The MARS 12084 features three clearly marked terminals: 'C' for Common, 'Herm' for the compressor (75 MFD), and 'Fan' for the condenser fan motor (10 MFD). Always verify your wiring against the unit’s schematic before installation.

Can I use a 440V capacitor to replace this 370V model?
Yes, technicians often use 440Vac capacitors to replace 370Vac models as they offer higher voltage resilience. However, you must never replace a 440V capacitor with a 370V model, as the lower voltage rating will lead to immediate failure.

What are the signs that this capacitor needs replacement?
Common diagnostic indicators include a bulging or "mushroomed" top, leaking dielectric fluid, a compressor that hums but fails to start, or if a multimeter reading shows the microfarads have dropped below 10% of the rated 75/10 value.
