Replaces / Cross-Reference Part Numbers

• Replaces any oval-shaped 5 MFD capacitor with either a 370VAC or 440VAC rating.
• Compatible replacement for CBB65 type capacitors with matching specifications.
• Interchangeable with capacitors from brands such as Aerovox, TEMCo, ClimaTek, and others meeting the same MFD and voltage ratings.

Compatibility & Fitment

• Designed for continuous duty in single and three-phase AC motor applications.
• Commonly used in:
• Air conditioner condenser fan motors
• Furnace blower motors
• Heat pumps
• Pool and spa pumps
• Compressors
• Physical Dimensions: 2.0 in Width x 2.5 in Height x 1.25 in Depth (approximate case size).

When to Replace

• Motor produces a humming sound but fails to start.
• The capacitor case is visibly swollen, bulging, or leaking fluid.
• Capacitance measures outside the rated tolerance (below 4.75 uF or above 5.25 uF) when tested with a multimeter.

Installation Tips

• Disconnect all electrical power to the equipment before beginning work.
• Safely discharge the existing capacitor by shorting the terminals with a resistor or an insulated tool.
• Confirm the uF (MFD) rating and voltage of the new capacitor match the component being replaced.
• Note the wiring configuration before disconnecting the old part.
• Ensure all electrical connections are tight and secure after installation.
