Trane Service First SFCAP70D75440R Dual Run Capacitor 70+7.5 MFD 370/440V Round


The Trane Service First SFCAP70D75440R is a factory-authorized OEM replacement part engineered to serve as the critical electrical "brain" and power stabilizer for high-capacity condensing units. Designed specifically for high-SEER Trane and American Standard air conditioner and heat pump series, this dual-run component manages the precise energy sequencing required by both the heavy-duty compressor and the condenser fan motor. By facilitating a clean phase shift, it ensures your heating and cooling system initiates cycles efficiently, protecting expensive motor windings from heat-related stress and maintaining your furnace system's overall operational health.


Key Features:

  • True OEM Specification: The SFCAP70D75440R is an official Service First part, ensuring it meets the exact microfarad requirements and safety standards of your original Trane unit.
  • Dual Run Capacity: Features a 70+7.5 MFD configuration to support the simultaneous operation of high-tonnage compressors (HERM) and fan motors (FAN).
  • Resolves Start-Up Failures: Directly fixes specific humming noises and "hard-starting" issues where the motor struggles to turn over under high head pressure.
  • Advanced Safety Interrupter: Equipped with a 10,000 AFC pressure-sensitive internal safety switch designed to disconnect the capacitor in the event of an internal short.
  • Industrial Durability: Rated for 440VAC to handle higher voltage spikes and extreme outdoor heat far more effectively than standard 370V alternatives.

🛠️ HVAC Depot Pro Tip:

Before handling any electrical storage components, disconnect the main power at the outdoor disconnect box and discharge the capacitor by shorting the terminals with an insulated-handle screwdriver. Take a Picture First of the wiring configuration—specifically the colors leading to the "C" (Common), "HERM" (Compressor), and "FAN" (Fan Motor) terminals. During your diagnostic check, ensure the mounting strap is tightened securely to prevent vibration, which can lead to premature terminal failure.
