- Replaces any start capacitor with matching capacitance (270-324 MFD) and voltage (330 VAC or higher) specifications.
Compatibility & Fitment
- Designed for intermittent duty cycles in single-phase AC motor starting circuits.
- Commonly used in HVAC units, pool pumps, well pumps, and other electric motor applications.
- This is a start capacitor and cannot be used as a replacement for a run capacitor.
When to Replace
- Motor hums but does not start or struggles to start.
- Circuit breaker trips at motor startup.
- Visible signs of damage to the old capacitor, such as bulging, cracking, or leaking fluid.
- The motor starts slowly or requires manual assistance to get started.
Installation Tips
- Disconnect all electrical power to the unit before servicing.
- Safely discharge the old capacitor by shorting the terminals with an insulated screwdriver.
- Ensure the replacement capacitor's microfarad (uf/MFD) rating is within 10% of the original part.
- The voltage rating of the replacement capacitor must be equal to or greater than the original.
- Professional installation is recommended.
