Replaces / Cross-Reference Part Numbers

• Replaces any CBB61 capacitor with matching 4uF+4uF+2.5uF capacitance and a 250V or 300V AC voltage rating. Direct replacement is based on matching electrical specifications, not a specific part number.

Compatibility & Fitment

• Designed for starting and running single-phase motors in 50Hz/60Hz AC power systems.
• Commonly used in 3-speed ceiling fans from various manufacturers.
• Also suitable for other applications requiring these specifications, such as small motors, air movers, water pumps, and ventilators.
• Verify the microfarad (uF) values, voltage, and number of wires on your original capacitor before ordering.

When to Replace

• Ceiling fan blades turn slowly or not at all.
• Fan motor hums but does not start.
• Fan speeds do not change or work correctly.
• The original capacitor shows physical signs of failure, such as bulging, cracking, or leaking oil.

Installation Tips

• Disconnect electrical power at the source (circuit breaker or fuse box) before beginning installation.
• Photograph or draw a diagram of the original wiring configuration for reference.
• Discharge the old capacitor by carefully touching its wire leads together with an insulated screwdriver.
• Connect the new capacitor by matching the wire colors and functions to your original diagram.
• Ensure all electrical connections are secure before restoring power.
