Introduction
This manual provides essential information for the safe and effective use of the YWBL-WH CBB60 Run Capacitor. This component is designed to facilitate the start-up and continuous operation of single-phase AC motors, commonly found in air conditioners, air compressors, and other motor-driven equipment. Please read this manual thoroughly before installation and operation to ensure proper function and safety.
Safety Information
WARNING: Electrical components can cause serious injury or death. Installation and maintenance should only be performed by qualified personnel. Always disconnect power before working with electrical circuits.
- Ensure the power supply is completely disconnected and locked out before attempting any installation, removal, or maintenance.
- Verify that the capacitor's voltage and capacitance ratings match the requirements of your motor and system.
- Avoid touching the capacitor terminals or wires when power is connected. Capacitors can store an electrical charge even after power is disconnected.
- Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses.
- Do not use the capacitor if it shows signs of physical damage, leakage, or swelling.
- Dispose of old capacitors according to local regulations.

Setup and Installation
Proper installation is crucial for the safe and efficient operation of your motor. Follow these steps carefully:
- Disconnect Power: Before beginning any work, ensure the main power supply to the motor or appliance is completely disconnected and secured to prevent accidental re-energization.
- Identify Old Capacitor: Locate the existing run capacitor in your motor system. Note its physical dimensions and electrical ratings (µF and VAC) for comparison.
- Discharge Old Capacitor: Capacitors can store a dangerous electrical charge. Safely discharge the old capacitor using an insulated screwdriver with a resistive load or a specialized capacitor discharge tool. Do not short the terminals directly.
- Remove Old Capacitor: Carefully disconnect the wires from the old capacitor. Note the wiring configuration (e.g., which wire connects to which terminal).
- Install New Capacitor: Connect the wires from your motor system to the leads of the new YWBL-WH CBB60 capacitor. Ensure connections are secure and properly insulated. The CBB60 capacitor typically has two leads; connect them according to the motor's wiring diagram.
- Secure Capacitor: Mount the new capacitor securely in its designated location, ensuring it is not exposed to excessive vibration or heat.
- Verify Connections: Double-check all wiring connections to ensure they are correct and tight.
- Restore Power: Once installation is complete and verified, restore power to the motor system.

Operation
The CBB60 run capacitor is a critical component in single-phase AC motors. It provides a phase shift to the auxiliary winding, creating a rotating magnetic field necessary for motor start-up and efficient continuous operation. Once installed, the capacitor operates automatically as part of the motor's electrical circuit. It helps maintain a stable current flow and improves the motor's power factor and efficiency during its running cycle.
Maintenance
Run capacitors are generally maintenance-free components. However, periodic inspection can help identify potential issues before they lead to motor failure.
- Visual Inspection: Periodically inspect the capacitor for any signs of physical damage, such as swelling, bulging, cracks, or leakage. These are indicators of capacitor failure.
- Temperature Check: Ensure the capacitor is operating within its specified temperature range. Excessive heat can shorten its lifespan.
- Cleanliness: Keep the area around the capacitor clean and free from dust and debris to ensure proper heat dissipation.
- Professional Check: If the motor exhibits signs of reduced performance (e.g., slow start, humming, overheating), have a qualified technician check the capacitor's capacitance value with a multimeter.
Troubleshooting
If your motor is not functioning correctly, the run capacitor might be a contributing factor. Here are some common issues and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor hums but does not start | Failed run capacitor, incorrect wiring | Disconnect power, discharge capacitor, test capacitance. Replace if faulty. Verify wiring. |
| Motor starts slowly or runs weakly | Degraded run capacitor, incorrect capacitance | Disconnect power, discharge capacitor, test capacitance. Replace if value is significantly lower than rated. |
| Capacitor is visibly swollen or leaking | Internal failure, overheating, overvoltage | Immediately disconnect power. Safely remove and replace the capacitor. Investigate cause of failure (e.g., power supply issues). |
| Motor overheats | Faulty run capacitor, motor overload | Check capacitor. Ensure motor is not overloaded. |
If troubleshooting steps do not resolve the issue, consult a qualified electrician or appliance repair technician.
