1. Introduction
This manual provides essential information for the safe and effective use of the BOJACK CBB65 30uF 450V AC Motor Run Capacitor. This capacitor is designed for starting and running AC motors in various applications, including air conditioners, compressors, and general-purpose motors operating at 50 Hz/60 Hz frequencies. Please read this manual thoroughly before installation and operation.
2. Safety Information
WARNING: Electrical components can store dangerous charges even when power is disconnected. Always exercise extreme caution when handling capacitors.
- Always disconnect power to the appliance or motor before attempting any installation, replacement, or maintenance.
- Discharge the capacitor completely before touching its terminals. Use a properly insulated screwdriver with an insulated handle to short the terminals, or use a resistor designed for capacitor discharge.
- Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses.
- If you are not confident in performing electrical work, consult a qualified electrician or HVAC technician.
- Ensure the replacement capacitor matches the original specifications (Microfarad/MFD and Voltage) or is a suitable upgrade as described in this manual.

4. Setup and Installation
This capacitor is typically used as a replacement part in HVAC systems, motors, and other appliances. Follow these general steps for installation:
- Disconnect Power: Turn off the main power supply to the appliance or motor at the circuit breaker or fuse box. Verify power is off using a voltage tester.
- Locate Old Capacitor: Open the access panel of the appliance and locate the existing capacitor. Note its position and wiring connections.
- Discharge Old Capacitor: Carefully discharge the old capacitor using a properly insulated tool. Short the terminals together to release any stored electrical charge.
- Disconnect Wiring: Take a photo or draw a diagram of the wiring connections before disconnecting the wires from the old capacitor. Carefully remove the wires.
- Remove Old Capacitor: Unmount the old capacitor from its bracket.
- Install New Capacitor: Mount the new BOJACK CBB65 capacitor securely in the same location.
- Connect Wiring: Reconnect the wires to the new capacitor terminals according to your diagram or photo. Ensure all connections are tight and secure.
- Close Access Panel: Securely close the access panel of the appliance.
- Restore Power: Turn the main power supply back on.
- Test Operation: Test the appliance or motor to ensure it is functioning correctly.
Compatibility Note: A 450V capacitor can be used to replace a 370V capacitor because it is built to handle higher voltage, providing a safety margin. However, a 370V capacitor cannot be used to replace a 450V capacitor.
5. Operating Instructions
The BOJACK CBB65 capacitor is a passive component designed to assist in the starting and continuous running of AC motors. Once correctly installed, it operates automatically as part of the motor's electrical circuit. No user interaction is required for its operation.
Its primary function is to create a phase shift in the motor windings, providing the necessary torque for the motor to start and run efficiently. Ensure the motor is operating within its specified voltage and frequency ranges for optimal capacitor performance and longevity.
6. Maintenance
Capacitors are generally maintenance-free components. However, periodic inspection can help identify potential issues before they lead to motor failure.
- Visual Inspection: Annually inspect the capacitor for any signs of swelling, bulging, leaks, or corrosion around the terminals. These are indicators of capacitor failure.
- Cleanliness: Ensure the capacitor and its terminals are free from dust, dirt, and debris, which can affect heat dissipation and lead to premature failure.
- Secure Connections: Check that all wire connections to the capacitor terminals are secure and free from looseness.
- Replacement: If the motor exhibits symptoms of a failing capacitor (e.g., humming but not starting, slow start, reduced efficiency), consider testing and replacing the capacitor. Always replace with a capacitor of the correct specifications.
7. Troubleshooting
If your motor or appliance is not functioning correctly, a faulty capacitor might be the cause. Here are some common issues and potential solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Motor hums but does not start | Failed start capacitor (open circuit) | Test capacitor with a multimeter. Replace if faulty. |
| Motor starts slowly or runs sluggishly | Weak run capacitor (reduced capacitance) | Test capacitor with a multimeter. Replace if capacitance is significantly lower than rated. |
| Motor overheats | Incorrect capacitor value or failing capacitor | Verify capacitor specifications. Replace if faulty or incorrect. |
| Visible bulging or leaking from capacitor | Catastrophic capacitor failure | Immediately disconnect power and replace the capacitor. |
Always ensure power is disconnected and the capacitor is discharged before performing any troubleshooting or replacement.
