Compatibility & Fitment

  • Designed for intermittent duty in single-phase AC motor starting circuits.
  • Universal replacement for capacitors with a 270-324 MFD capacitance and a 330 VAC or higher voltage rating.
  • Suitable for various motor-driven applications including HVAC, pumps, compressors, and machinery.

When to Replace

  • Motor hums but does not start or struggles to start.
  • Start cycle is slow or requires manual assistance.
  • Circuit breaker trips repeatedly during motor startup.
  • Visible damage to the existing capacitor, such as bulging, cracking, or fluid leakage.

Installation Tips

  • Disconnect all electrical power to the unit before performing any service.
  • Safely discharge the existing capacitor by shorting the terminals with an insulated tool.
  • Verify the uf/MFD and VAC ratings of the new capacitor match the component being replaced.
  • Ensure connections are secure and the capacitor is mounted properly.
  • Professional installation is recommended for those unfamiliar with electrical work.

FAQ

A failing start capacitor often presents as a motor that hums but fails to reach full speed, or one that trips the breaker upon startup. If you notice a clicking sound, a burning smell, or if the top of the capacitor appears domed or swollen, it is likely faulty and requires replacement.
This is a universal-style start capacitor designed for use in various electric motor applications, including air conditioner condensers, heat pump systems, and general-purpose HVAC motors requiring a 270-324 uF rating at 330 VAC.
Yes, as long as the electrical specifications match. This unit cross-references with common part numbers such as 092A270B330CE7A, CON-270-330, 11970, and 61B7D330270NCMS. Always ensure your original capacitor has the same microfarad (uF/MFD) range and voltage rating (VAC) before installing.
Installation typically takes 15 to 30 minutes. You will need a screwdriver to remove the access panel and a pair of insulated needle-nose pliers to disconnect the terminals. Always ensure the power is completely disconnected at the breaker before beginning.
Before removing the old part, take a photo of the wiring configuration to ensure the new capacitor is connected correctly. Because capacitors store an electrical charge even when the power is off, you must safely discharge the old capacitor by touching the terminals with an insulated screwdriver before handling it.
This round capacitor measures approximately 1.75 inches in diameter and 3.38 inches in height. Please verify that you have sufficient clearance in your motor housing for these dimensions before purchasing.
