Replaces / Cross-Reference Part Numbers

  • Replaces any round motor start capacitor with matching capacitance and voltage specifications.
  • Compatible with generic type CD60 capacitors.

Compatibility & Fitment

  • Designed for intermittent duty in single-phase AC motor starting circuits.
  • Common applications include HVAC units, air compressors, well pumps, and other electric motors.

When to Replace

  • Motor hums but fails to start or starts slowly.
  • Circuit breaker trips at motor startup.
  • Capacitor shows physical damage such as bulging, cracking, or leaking fluid.
  • Capacitance measures outside of the 189-227 uF range when tested with a multimeter.

Installation Tips

  • Disconnect all electrical power to the equipment before servicing.
  • Safely discharge the existing capacitor by shorting the terminals with an insulated screwdriver or appropriate tool.
  • Ensure the replacement capacitor's uF/MFD rating matches the original component.
  • The voltage rating of the new capacitor must be equal to or greater than the original.
  • This is a non-polarized capacitor; wires can be connected to either terminal.

FAQ

If your pool or well pump motor is humming but failing to start, or if the motor takes an unusually long time to reach full speed, the start capacitor is likely failing. You may also notice the motor overheating or tripping the circuit breaker upon startup.
This is a universal CBB60 round start capacitor designed for single-phase motors requiring a 189-227 uF rating at 125 VAC. It is commonly used in pool pumps, well pumps, HVAC systems, and air compressors. Always verify that your existing capacitor matches these exact electrical specifications before installation.
This unit replaces various OEM motor start capacitors, including MARS 11915 and BMI 092A189B125AC1A. It is a suitable replacement for any motor start application requiring a 189-227 uF, 110-125 VAC specification.
Installation is straightforward and typically takes 15-20 minutes. You will need a screwdriver to remove the capacitor housing cover and a pair of needle-nose pliers to disconnect the spade terminals. Ensure the power is completely disconnected from the pump before beginning. It is recommended to discharge the old capacitor with an insulated screwdriver across the terminals before handling.
Before installing the new unit, inspect the motor for signs of seized bearings or debris that could cause high starting torque, as these conditions can cause a new capacitor to fail prematurely. Additionally, ensure the wire connections are clean and tight; loose or corroded terminals can lead to arcing and poor electrical contact.
