Replaces / Cross-Reference Part Numbers

  • Direct replacement for any round motor start capacitor with the same capacitance, voltage, and frequency specifications.

Compatibility & Fitment

  • Designed for single-phase AC electric motor starting applications.
  • Commonly used in air conditioners, heat pumps, compressors, pool pumps, and other electric motors.
  • Verify physical dimensions for proper fit in the mounting bracket and housing.

When to Replace

  • Motor hums but fails to start or starts slowly.
  • Circuit breaker trips when the motor attempts to start.
  • Visible signs of damage on the old capacitor, such as bulging, cracking, or leaking fluid.

Installation Tips

  • Disconnect all electrical power to the equipment before servicing.
  • Safely discharge the existing capacitor before handling to avoid electrical shock.
  • Note or photograph the original wire connections before disconnecting the old capacitor.
  • Ensure the replacement capacitor's voltage rating is equal to or greater than the original.
  • Match the capacitance range (145-175 MFD) of the original capacitor.

FAQ

Common symptoms include the motor humming or buzzing without turning, the motor struggling to reach full speed, or the equipment tripping the circuit breaker upon startup. If the capacitor casing appears bulging, leaking, or shows signs of burn marks, it has failed and requires immediate replacement.
This capacitor is designed for single-phase AC motor applications operating at 50/60 Hz. It is commonly used in pool pumps, well pumps, air compressors, pressure washers, HVAC systems, and various industrial electric motors requiring a 145-175 uF start rating.
No, you must match the MFD (microfarad) rating specified by your motor's nameplate. Using a capacitor with a significantly different MFD rating can prevent the motor from starting correctly or cause permanent damage to the motor windings.
This is a non-polarized capacitor, meaning it can be connected in either direction. However, ensure the terminals are securely fastened and the capacitor is mounted in a dry, well-ventilated area away from direct heat sources to extend its service life.
Always disconnect the power supply to the equipment before beginning. Even when unplugged, capacitors can hold a dangerous electrical charge. Use an insulated screwdriver to short across the terminals to safely discharge any stored energy before handling the unit.
This unit measures approximately 1.44 inches in diameter and 3.38 inches in height. Ensure you have sufficient clearance in your motor housing or capacitor box before installation.
