Replaces / Cross-Reference Part Numbers

• Direct replacement for any CBB61 capacitor with matching 5uf+5uf capacitance, 4-wire configuration, and a 250V AC or higher voltage rating.

Compatibility & Fitment

• Designed for use in ceiling fans to control start and run speeds.
• Also suitable for other single-phase AC motors found in wall fans, stand fans, and ventilation systems.
• The dual 5uf capacitance values are commonly used for multi-speed fan control.
• Verify capacitance (uf), voltage (V), and physical dimensions for proper fit and function.

When to Replace

• Fan runs at only one speed or fan speeds are incorrect.
• Fan blades rotate slowly or require a manual push to start.
• Audible humming from the motor without blade rotation.
• Original capacitor shows signs of physical damage, such as bulging, cracking, or leaking.

Installation Tips

• Always disconnect power at the circuit breaker before servicing the fan.
• Photograph or sketch the original wiring configuration before removing the old capacitor.
• Match wire functions based on your diagram, as wire colors can differ between manufacturers.
• Ensure the replacement capacitor's voltage rating is equal to or higher than the original part.
• Capacitance (uf) values should closely match the original specification for optimal motor performance.
• Secure all wire connections and mount the new capacitor firmly inside the fan housing.
