Replaces / Cross-Reference Part Numbers

  • Direct replacement for any CBB61 capacitor with a 4.5µF capacitance rating.
  • Can replace capacitors with a voltage rating of 450V or lower.

Compatibility & Fitment

  • Designed for starting and operating single-phase motors.
  • Commonly used in ceiling fans, wall fans, and stand fans.
  • Suitable for other small motor applications requiring a 4.5µF capacitor.
  • Verify physical dimensions to ensure proper fit within the motor housing.

When to Replace

  • Fan blades rotate at a slower than normal speed.
  • Fan motor hums but does not start.
  • Fan requires a manual push to start rotating.
  • Fan speeds are not changing or are limited to one speed.

Installation Tips

  • Disconnect all power to the fan before beginning installation.
  • Take a photograph of the original wiring configuration for reference.
  • The capacitance value (µF) must match the original capacitor exactly.
  • The voltage rating of the new capacitor can be the same or higher than the original, but not lower.
  • The two wires are non-polarized and can be connected in any order.

FAQ

If your ceiling fan is struggling to start, hums without spinning, or runs significantly slower than usual, the capacitor is likely failing. If you have to give the blades a manual push to get them moving, it is a clear sign that the capacitor can no longer provide the necessary torque to start the motor.
It is important to match the microfarad (μF) rating as closely as possible to your original part. While a small variance of ±5% is generally acceptable, using a capacitor with a significantly different rating can cause the motor to overheat, run inefficiently, or fail to start entirely.
Yes, this 450V capacitor is compatible with ceiling fans originally equipped with 250V, 300V, 350V, or 400V capacitors. The voltage rating on a capacitor indicates the maximum voltage it can handle; using a higher-rated replacement is safe and will not damage your fan.
Installation is straightforward and typically takes 15 to 30 minutes. You will need a screwdriver to access the fan's housing and wire nuts or electrical tape to secure the connections. Always ensure the power is turned off at the breaker before beginning.
No, this is a non-polarized capacitor. You can connect either of the two wires to the fan's motor leads without concern for orientation.
Ceiling fan capacitors are exposed to heat generated by the motor and the environment. Over time, the internal film degrades, leading to a loss of capacitance. This is a common wear-and-tear issue and does not necessarily indicate a problem with the fan motor itself.
