Compatibility & Fitment

  • Designed for single-phase motor starting applications.
  • Commonly used in HVAC units, air conditioners, compressors, and water pumps requiring a capacitor with matching specifications.

When to Replace

  • Motor hums but fails to start or starts slowly.
  • Capacitor shows physical damage such as bulging, cracking, or leaking fluid.
  • Multimeter test shows capacitance reading outside the 216-259 uF range.

Installation Tips

  • Disconnect all electrical power to the unit before servicing.
  • Safely discharge the existing capacitor by shorting the terminals with an insulated screwdriver.
  • Verify that the voltage and uF/MFD ratings of the new capacitor match the original component.
  • Note the wire placement on the old capacitor terminals before disconnecting.

    FAQ

    This capacitor is generally used as a start capacitor in single-phase electric motors that require a CD60 round capacitor rated at 216-259 microfarads (uF/MFD) and 110-125 VAC. It may be found in some AC motor, fan, compressor, blower, or heat pump applications, but fitment depends on matching the original capacitor's microfarad range, voltage rating, case style, and terminal configuration. The safest match is by the numbers printed on your old capacitor and the equipment model.
    216-259 uF and MFD both refer to capacitance; uF and MFD are commonly used to mean the same thing in this context. The 110-125 VAC rating is the capacitor's voltage class. CD60 is a common designation for a motor start capacitor, typically used briefly during startup rather than continuously during normal operation.
    Common signs of a failed start capacitor include a motor that hums but does not start, hard starting, slow startup, intermittent tripping of overload protection, or a fan/compressor that needs a manual push to begin turning. In some cases the capacitor may look swollen, cracked, leaking, or have a burnt smell, but capacitors can also fail with no visible damage.
    The microfarad rating should match the original capacitor's specified range as closely as possible. A significant mismatch can cause poor starting performance or motor damage. The voltage rating should not be lower than the original. If your old part shows 216-259 uF and 110-125 VAC with a similar round CD60 style, this is the type of match you want to confirm.
    Based on the CD60 designation, this is a start capacitor. Start capacitors are designed to assist the motor during startup and are usually taken out of the circuit by a relay or switch once the motor reaches speed. They are not the same as continuous-duty run capacitors, so you should verify your original part type before ordering.
    First disconnect power completely and discharge the old capacitor safely, since capacitors can hold a dangerous charge. Verify the old capacitor's microfarad rating, voltage rating, shape, and terminal layout. It is also smart to inspect related components such as the start relay, potential relay, centrifugal switch, wiring terminals, and the motor itself, because a weak capacitor may be a symptom of another electrical problem.
    For someone familiar with electrical repairs, replacement is usually straightforward and often takes about 15 to 30 minutes. Typical tools include screwdrivers, needle-nose pliers, and a camera or phone to record wire positions before removal. If you are not comfortable working around stored electrical charge or line-voltage equipment, installation is best left to a qualified technician.
