  • Replaces parts from brands such as BMI, Appli Parts, and others sharing the same MFD, voltage rating, and physical size.
  • Common model type: CD60

Compatibility & Fitment

  • Designed for intermittent duty in AC motor starting circuits.
  • Suitable for single-phase electric motors requiring a start capacitor for initial torque.
  • Commonly used in well pumps, HVAC units, air compressors, refrigeration systems, and other motor-driven equipment.
  • Verify physical dimensions to ensure a proper fit within existing mounting brackets or enclosures.

When to Replace

  • Motor hums but fails to start or struggles to reach full speed.
  • Circuit breaker trips upon motor startup.
  • Capacitor shows physical damage, such as bulging, cracking, or leaking fluid.
  • Capacitance measures outside the 145-175 MFD range when tested with a multimeter.

Installation Tips

  • Disconnect all electrical power to the equipment before beginning installation.
  • Safely discharge the old capacitor by shorting the terminals with a resistor or an insulated tool.
  • Confirm the voltage rating of the new capacitor is equal to or greater than the original.
  • Ensure the MFD (uf) range of the new capacitor matches the manufacturer's requirement for the motor.
  • Note the wiring configuration before disconnecting the old capacitor to ensure correct installation.

    FAQ

    Match the electrical specifications on your original capacitor exactly where required: this part is rated 145-175 uF (MFD), 110-125 VAC, 50/60 Hz, and uses a round start-capacitor form factor. It is typically used on motors that require a start capacitor in that exact microfarad range and voltage class. The safest match is to compare the old capacitor's uF/MFD rating, VAC rating, shape, and terminal style to the replacement before ordering.
    145-175 uF is the capacitor's capacitance range, sometimes printed as MFD or microfarads. For a start capacitor, that range is critical to motor starting performance. In most cases, you should replace it with the same microfarad rating range listed by the equipment manufacturer or printed on the original capacitor. Using the wrong capacitance can cause hard starting, overheating, humming, or failure to start.
    Common signs include the motor humming but not starting, the fan or motor needing a manual push to begin turning, intermittent starting, tripped breakers, overheating, or a burnt electrical smell. A failed start capacitor may also show visible swelling, leakage, or a ruptured case, but some bad capacitors fail with no obvious exterior damage.
    It can be used on equipment that specifically calls for a round start capacitor with a 145-175 uF rating and 110-125 VAC rating. That may include certain AC condenser fan or electric motor applications, but compatibility is determined by the original capacitor specifications and the motor's design, not by equipment type alone. Always verify the rating on your existing part or wiring diagram.
    Replacement is usually a straightforward electrical repair for someone familiar with safely servicing motors. Typical tools include a screwdriver or nut driver to open the access panel, needle-nose pliers for terminals, and a multimeter or capacitance meter for testing. Many replacements take about 15 to 30 minutes, but power must be disconnected first and the capacitor must be safely discharged before handling.
    Inspect the wiring terminals for corrosion or heat damage, confirm the motor shaft spins freely, and look for causes of hard starting such as worn bearings, low supply voltage, a stuck relay, or excessive mechanical load. If the old capacitor failed from overheating, also check airflow, dirt buildup, and the motor's start circuit components so the new capacitor does not fail prematurely.
    A start capacitor provides a high burst of capacitance to help a motor begin turning, then it is typically removed from the circuit by a relay or switch. A run capacitor stays in the circuit during operation and usually has a much lower microfarad rating. This part is a start capacitor, so it should only be used where the equipment is designed for a start-capacitor application.
