Replaces / Cross-Reference Part Numbers

• Replaces capacitors with markings such as CBB65.
• Direct substitute for parts from brands including Genteq, Packard, Titan, and Mars with matching specifications.

Compatibility & Fitment

• Designed for continuous use in single-phase motor applications.
• Commonly used in HVAC systems, air conditioners, heat pumps, condenser units, compressors, and other electric motors.
• A 440V capacitor can safely replace a 370V unit with the same MFD rating.
• Ensure the physical dimensions (diameter and height) match the available space in your equipment.

When to Replace

• The motor hums but does not start or requires a manual push to start.
• Visible damage to the old capacitor, such as a bulging or swollen case, or fluid leakage.
• The fan or compressor in an HVAC unit fails to turn on.
• Capacitance reading on the existing capacitor is outside its rated tolerance (e.g., below 33.25 MFD or above 36.75 MFD for a ±5% unit).

Installation Tips

• Warning:Capacitors can store a dangerous electrical charge. Disconnect all power to the unit before servicing.
• Safely discharge the existing capacitor by shorting the terminals with an insulated-handle screwdriver.
• Note or photograph the wire connections before removing the old capacitor to ensure correct installation.
• Connect the wires to the corresponding terminals on the new capacitor. Polarity is not a concern for AC motor run capacitors.
• Secure the new capacitor with the original mounting bracket.
