60+10 uF 60/10 MFD ±5% 370V/440 VAC Volts CBB65 Dual Run Circular Start Capacitor

Key Features

  • Capacitance: 60 + 10 Microfarad (MFD)
  • Voltage Rating: 370V / 440V AC
  • Tolerance: ±5%
  • Frequency: 50 / 60 Hz
  • Shape: Round
  • Case Material: Aluminum, oil-filled
  • Terminals: 3-terminal (C, HERM, FAN) with 1/4 inch male quick-connects
  • Operating Temperature Range: -40 °C to +70 °C
  • Safety Standard: Meets EIA-456-A requirements

Replaces / Cross-Reference Part Numbers

  • Replaces any dual round motor run capacitor with matching 60/10 MFD and 370 VAC or 440 VAC specifications.
  • Direct replacement for capacitors from brands including Titan, Supco, and Packard.
  • Commonly replaces parts with numbers such as P291-6014R, CBB65, and USA2236.

Compatibility & Fitment

  • Designed for HVAC applications including air conditioners, heat pumps, and condensing units.
  • Powers two electric motors, such as a compressor motor (HERM) and a fan motor (FAN).
  • Fits units from major manufacturers such as Trane, Carrier, Goodman, Lennox, Rheem, and others that specify a 60/10 MFD capacitor.

When to Replace

  • Compressor or fan motor hums but fails to start.
  • Motor starts and runs intermittently or with low power.
  • Visible bulging, swelling, or fluid leakage from the capacitor case.
  • Capacitance measures outside the ±5% tolerance when tested with a multimeter.

Installation Tips

  • Disconnect all electrical power to the equipment before servicing.
  • Safely discharge the old capacitor using a resistor or an insulated tool across the terminals.
  • Verify the MFD (uf) and voltage ratings of the old capacitor. The MFD rating must match exactly. The voltage rating of the replacement must be equal to or greater than the original.
  • Note the wire placement on the old capacitor terminals (C, HERM, FAN) before disconnecting.
  • Ensure the new capacitor is secured with the original mounting strap or bracket.

FAQ

This is a dual-run capacitor, meaning it houses two capacitors in one unit. The 60 uF side is designed to power the main compressor motor, while the 10 uF side powers the fan motor. It is essential that your replacement matches these exact microfarad (uF) ratings to ensure your motors start and run at the correct torque.
Yes. A capacitor rated for 440 VAC is fully compatible with systems originally requiring 370 VAC. The voltage rating indicates the maximum voltage the capacitor can handle; using a 440 VAC unit in a 370 VAC application provides a higher safety margin and often results in a longer service life.
The most common signs include the AC unit humming but failing to start, the fan motor struggling to spin or requiring a push to get moving, or the system blowing warm air because the compressor is not engaging. If you notice the top of the capacitor is domed or bulging, it has failed and requires immediate replacement.
Installation is generally straightforward and takes about 15–30 minutes. You will need a screwdriver to remove the AC service panel and a pair of insulated needle-nose pliers to disconnect the wires. Always ensure the power to the unit is completely shut off at the breaker before beginning, and use an insulated screwdriver to safely discharge the old capacitor by touching the terminals before handling it.
Capacitors are heat-sensitive components and naturally degrade over time due to constant exposure to high temperatures and electrical stress. Before installing the new part, inspect the contactor for pitted or burnt points, as a failing contactor can cause premature capacitor failure. Additionally, ensure your condenser coils are clean to prevent the system from running at excessively high pressures, which puts extra strain on the capacitor.
