[Lifetime Warranty] 70 uF MFD 370/440 VAC ±5% Round Run Capacitor 50/60 Hz AC Electric Replacement

[Lifetime Warranty] 70 uF MFD 370/440 VAC ±5% Round Run Capacitor 50/60 Hz AC Electric Replacement

70/5 uF MFD 370-440 VAC Round Dual Run Capacitor

Key Features

  • Capacitance Rating: 70 + 5 Microfarad (uF/MFD)
  • Voltage Rating: 370 or 440 Volts AC (VAC)
  • Tolerance: ±5%
  • Frequency: 50 / 60 Hz
  • Shape: Round
  • Construction: Aluminum case with metallized polypropylene film
  • Terminals: Three terminals labeled C (Common), HERM (Compressor), and FAN
  • Operational Life: Tested for up to 60,000 hours of service life
  • Operating Temperature: -40°C to +70°C

Replaces / Cross-Reference Part Numbers

  • Replaces any round dual run capacitor with matching 70/5 uF MFD and 370V or 440V specifications.
  • Suitable replacement for parts from brands such as JARD, MARS, TEMCo, ClimaTek, Titan Pro, and others.
  • Common part numbers include: C3705R, TRCFD705, 97F9895, P291-7054R, CBB65-R.
  • Always verify physical dimensions (diameter and height) for proper fit.

Compatibility & Fitment

  • Designed for use in HVAC systems, including air conditioners and heat pumps.
  • Provides starting and running torque for a compressor motor (70 uF side) and a fan motor (5 uF side) in a single unit.
  • Compatible with units from major manufacturers provided the capacitance, voltage, and physical size specifications match the original part.

When to Replace

  • The compressor or fan motor hums but will not start.
  • The outdoor condenser unit fan spins slowly or requires a manual push to start.
  • Visible signs of failure on the existing capacitor, such as a bulging top, swelling, or oily residue leaking from the case.
  • The AC system is running but not blowing cold air.

Installation Tips

  • Warning: Disconnect all electrical power to the HVAC unit at the breaker panel and service disconnect before handling.
  • Safely discharge the old capacitor by shorting the terminals with a resistor or an insulated-handle screwdriver.
  • Note or photograph the wire connections to the C, HERM, and FAN terminals before disconnecting.
  • Install the new capacitor, ensuring it is secured by the original mounting bracket.
  • Connect the wires to the corresponding terminals on the new capacitor.
