Replaces / Cross-Reference Part Numbers

This component is a direct replacement for any round dual run capacitor with matching MFD and voltage specifications. It can replace both 370V and 440V capacitors. Common model types include:

• USA2222A
• CBB65B

Compatibility & Fitment

Used in air conditioners, heat pumps, and condensing units to start and run a compressor motor and a fan motor simultaneously. Compatible with units from major brands that require a 70/7.5 MFD round capacitor.

• 70 MFD side connects to the compressor motor.
• 7.5 MFD side connects to the fan motor.
• Verify physical dimensions for fitment in the existing mounting bracket.

When to Replace

A faulty capacitor can lead to motor failure. Consider replacement if you notice:

• AC unit or fan produces a humming noise but does not start
• Slow or delayed motor start-up
• Compressor or fan motor runs intermittently
• Visible swelling, bulging, or leaking from the capacitor case
• Capacitance measures outside the rated tolerance range

Installation Tips

• Disconnect all electrical power to the HVAC unit before servicing.
• Safely discharge the old capacitor by shorting the terminals with an insulated tool.
• Note or photograph the wire placement on the C, FAN, and HERM terminals before removal.
• Install the new capacitor and ensure it is secured by the mounting strap.
• Reconnect the wires to their corresponding terminals on the new capacitor.
