Replaces / Cross-Reference Part Numbers

• Replaces any round start capacitor with the same capacitance range and voltage rating. Verify that the physical dimensions are compatible with your application.

Compatibility & Fitment

• Designed for intermittent duty in single-phase AC motor starting circuits.
• Common applications include HVAC units, air compressors, well pumps, refrigeration systems, and other motor-driven equipment requiring a start capacitor with matching specifications.

When to Replace

• Motor hums but fails to start or struggles to start.
• Circuit breaker trips when the motor attempts to start.
• Visible damage to the old capacitor, such as bulging, leaking fluid, or cracks.

Installation Tips

• Disconnect all electrical power to the equipment before servicing.
• Safely discharge the existing capacitor by shorting the terminals with an insulated tool.
• Confirm the replacement capacitor's specifications match the original component. The voltage rating must be equal to or greater than the original.
• AC start capacitors are non-polarized and can be connected without regard to wire color.
