The Trane Service First SFCAP50D75440R is a factory-authorized OEM replacement part engineered to serve as the critical electrical "brain" and power stabilizer for high-demand condensing units. Designed specifically for Trane and American Standard air conditioner and heat pump series, this dual-run component manages the precise energy sequencing required by both the 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 air conditioners system's overall operational health. 


Key Features:

  • Genuine OEM Fit: Part number SFCAP50D75440R is a real Trane OEM replacement, built to the exact factory specifications of your original unit.
  • Dual Run Support: Features a 50+7.5 MFD rating to power the primary compressor (HERM) and the fan motor (FAN) simultaneously from a single canister.
  • Resolves Ignition Issues: Specifically engineered to eliminate "hard starts," humming noises, and startup failures caused by weakened legacy capacitors.
  • Advanced Safety Shielding: Equipped with an internal pressure-sensitive safety interrupter designed to disconnect the capacitor in the event of an internal fault.
  • Industrial Durability: Rated for 440VAC to handle higher voltage spikes and extreme outdoor cabinet temperatures far more effectively than standard 370V alternatives.

🛠️ HVAC Depot Pro Tip:

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