Replaces / Cross-Reference Part Numbers

• Commonly replaces CBB65A and CBB65B series capacitors
• Compatible with standard industry part numbers rated for 30 uF at 370V or 440V
• Suitable replacement for various generic HVAC motor run capacitor specifications

Compatibility & Fitment

• Designed for use in HVAC systems, including air conditioners, heat pumps, and condenser fan motors
• Suitable for general-purpose motor run and start-up applications
• Compatible with equipment requiring a 30 uF capacitor rating
• Verify diameter and height requirements against your current unit for proper physical fitment

When to Replace

• Visible bulging, swelling, or leaking on the top or sides of the capacitor
• Motor fails to start or struggles to reach operational speed
• Humming or buzzing sounds coming from the motor unit
• System performance decrease or frequent tripping of circuit breakers
• Measured capacitance falls outside the ±5% tolerance range when tested with a multimeter

Installation Tips

• Ensure power is completely disconnected from the HVAC unit before service
• Safely discharge the capacitor using an insulated screwdriver across terminals before handling
• Take a photograph of existing wiring configurations before removal to ensure correct reconnection
• Ensure terminals are clean and secure to prevent arcing and heat buildup
• Always match the microfarad (uF) rating exactly; the voltage rating must be equal to or greater than the original component
