Trane Service First SFCAP70440R Round Run Capacitor | 70 MFD 370/440V


The Trane Service First SFCAP70440R is a genuine OEM single-run capacitor designed to serve as the electrical "brain" and power stabilizer for high-demand HVAC motors. Engineered specifically for Trane and American Standard systems, this component provides the critical electrical boost and phase shift required for reliable compressor motor torque and efficiency. By maintaining stable energy flow, it prevents the overheating and "stalling" that lead to premature motor failure in various furnace-connected air handlers and condensing units. 


Key Features:

  • True OEM Specification: The SFCAP70440R is a factory-authorized replacement part built to the exact specifications of Trane HVAC equipment for a guaranteed fit and dependable performance.
  • Single Run Capacitance: Features a dedicated 70 MFD microfarad rating, optimized for supporting standard motor run performance in large-scale residential and commercial systems.
  • Resolves Motor Efficiency Issues: Designed to fix specific startup lags and humming by providing consistent electrical energy to compressor and fan motors.
  • Advanced Safety Protection: Constructed with a built-in UL-recognized safety pressure interrupter designed to interrupt up to 10,000 amps of fault current (AFC).
  • Heavy-Duty Construction: Encased in a hermetically sealed aluminum case with stainless steel cover, engineered to withstand extreme temperatures from -40°F to 158°F. 


Product Details:

  • Brand: Service First / Trane / American Standard
  • Manufacturer: Trane Technologies
  • Part #: SFCAP70440R (Replaces CPT01233)
  • Shipping Weight: Approximately 1.0 lb
  • Voltage: 370/440 VAC
  • Capacitance: 70 MFD
  • Shape: Round
  • Operating Life: 60,000 Hours 


🛠️ HVAC Depot Pro Tip:

Before beginning installation, ensure the furnace or outdoor unit power is completely disconnected at the breaker or service switch. Always discharge the old capacitor by shorting the terminals with an insulated-handle screwdriver to avoid high-voltage shocks. Take a Picture First of the wiring leads on the original unit; even single-run capacitors can be wired in complex series configurations within larger air handlers. During your diagnostic check, inspect the top of the aluminum can for any doming—a bulged top confirms the internal safety interrupter has tripped and the part must be replaced.
