Replaces / Cross-Reference Part Numbers

• Replaces any 2-wire CBB61 capacitor with a 5 uF rating.
• This 450V AC rated capacitor can safely replace units with lower voltage ratings such as 250V AC or 300V AC.

Compatibility & Fitment

• Designed for starting and running single-phase motors.
• Commonly used in ceiling fans, electric fans, range hoods, pumps, and small motors.
• Fitment depends on physical dimensions. Verify case size to ensure it fits in the available space.

When to Replace

• Fan blades rotate slowly, even on the highest setting.
• Fan motor hums but does not start or requires a manual push to begin rotating.
• One or more fan speed settings no longer function correctly.
• The original capacitor shows physical signs of failure, such as bulging, cracking, or leaking fluid.

Installation Tips

• Disconnect all electrical power to the fan at the circuit breaker or fuse box before beginning work.
• Safely discharge the existing capacitor before handling.
• Note the wire connections before removing the original part.
• As a non-polarized capacitor, the two wires can be connected to either circuit wire.
• The uF (microfarad) rating must match the original capacitor exactly for proper motor operation.
