Replaces / Cross-Reference Part Numbers

• Direct replacement for any oval capacitor with matching 15 uF capacitance and 370V or 440V rating.
• Verify physical dimensions for proper fit in the mounting bracket.

Compatibility & Fitment

• Designed for single and three-phase AC motor applications.
• Commonly used in HVAC systems, including air conditioner condensers, heat pumps, compressors, and fan motors.
• Compatible with equipment requiring a 15 MFD run capacitor for either 370 Volt or 440 Volt systems.

When to Replace

• Motor hums but fails to start or struggles to start.
• Fan blades rotate slower than normal or require a manual push to start.
• *AC unit is running but not blowing cold air.
• Visible damage to the existing capacitor, such as swelling, bulging, or fluid leakage.

Installation Tips

• Disconnect all electrical power to the equipment before beginning service.
• Safely discharge the existing capacitor by shorting the terminals with a resistor or an insulated screwdriver.
• Note the wire placement on the old capacitor terminals before disconnecting.
• Confirm the uF/MFD rating matches the original part exactly.
• The voltage rating of the replacement capacitor must be equal to or greater than the original (e.g., a 440V capacitor can replace a 370V, but not vice-versa).
• Secure the new capacitor in place and reconnect the wires to the correct terminals.
