Replaces / Cross-Reference Part Numbers

  • Replaces any start capacitor with the same capacitance and voltage ratings.
  • Commonly replaces parts with CD60 or 11919 model numbers.
  • Compatible replacement for capacitors from brands such as Jard, Titan, TEMCo, and Appli Parts with matching specifications.

Compatibility & Fitment

  • Designed for single-phase AC motor starting circuits.
  • Suitable for applications including HVAC units, air compressors, well pumps, and other electric motors requiring a start capacitor.
  • Ensure the Mfd/uF and VAC ratings match the original equipment manufacturer's specifications.

When to Replace

  • The motor hums but fails to start.
  • The motor starts slowly or requires manual assistance.
  • The capacitor case is bulging, cracked, or leaking fluid.
  • Capacitance measures outside the specified range when tested with a multimeter.

Installation Tips

  • Disconnect all electrical power to the equipment before servicing.
  • Safely discharge the existing capacitor by shorting its terminals with a properly insulated tool.
  • Verify the wire connections before removing the original part.
  • Install the new capacitor, ensuring a secure connection to the terminals. Start capacitors are non-polarized.

FAQ

If your pool or well pump motor hums but fails to start, or if the motor struggles to reach full speed, the start capacitor is often the culprit. Other signs include the motor tripping the circuit breaker immediately upon activation or the capacitor casing appearing swollen, leaking, or showing signs of heat damage.
This is a universal-style motor start capacitor rated for 270-324 uF and 110-125 VAC. It is compatible with many single-phase AC motors used in pool pumps, well pumps, and HVAC compressors. Always verify that your existing capacitor matches these exact microfarad (uF/MFD) and voltage (VAC) ratings before installation.
The MFD (Microfarads) rating must be within the specified range (270-324 uF) to provide the correct torque for your motor to start. The VAC rating indicates the maximum voltage the capacitor can handle. You should always replace a capacitor with one that matches the original MFD rating and has a voltage rating equal to or greater than the original.
Replacing a start capacitor is a straightforward task that typically takes 15 to 30 minutes. You will generally need a screwdriver to remove the pump housing and a pair of needle-nose pliers to disconnect the 1/4" male terminals. Ensure the power is completely disconnected and the capacitor is safely discharged before touching the terminals.
Before installing the new part, inspect the motor for signs of mechanical binding or seized bearings, as these can cause a capacitor to fail prematurely. Additionally, ensure the mounting area is clean and dry, and verify that the electrical connections are tight and free of corrosion to prevent future performance issues.
This round motor start capacitor measures approximately 1-7/16 inches in diameter and 2-3/4 inches in height. It features standard 1/4-inch male terminals for easy connection to your motor's existing wiring.
