Replaces / Cross-Reference Part Numbers

• Replaces any round dual run capacitor with matching 70/10 MFD and 370V or 440V specifications.
• Commonly replaces capacitors in CBB65 and similar series.

Compatibility & Fitment

• Designed for HVAC applications including air conditioners, heat pumps, and condenser units.
• Powers a compressor motor (HERM terminal) and a fan motor (FAN terminal).
• Verify specifications (uF, VAC, and physical dimensions) of the original capacitor before ordering.

When to Replace

• The fan motor runs but the compressor does not start.
• The compressor or fan hums but does not start.
• The unit starts but then shuts off intermittently.
• Visible signs of damage, such as a bulging or leaking capacitor case.
• Capacitance measures outside of the ¬±5% tolerance range when tested.

Installation Tips

• Disconnect all electrical power to the HVAC unit before servicing.
• Safely discharge the existing capacitor by shorting the terminals with an insulated screwdriver.
• Photograph or note the wire placement on the C, HERM, and FAN terminals before removal.
• Ensure the new capacitor is physically secured with the original mounting strap or bracket.
• Professional installation is recommended for those unfamiliar with HVAC electrical systems.
