Replaces / Cross-Reference Part Numbers

• Replaces any round dual run capacitor with matching specifications.
• Verify that the original capacitor has a 55+7.5 MFD rating.
• Compatible with both 370 VAC and 440 VAC applications.
• Ensure physical dimensions allow for a proper fit in the existing mounting bracket.

Compatibility & Fitment

• Designed for heavy-duty, continuous operation in single-phase motors.
• Commonly used in HVAC systems, air conditioners, heat pumps, and condenser fan motors.
• Serves as a replacement component for various brands of air conditioning and motor equipment where the electrical and physical specifications match.

When to Replace

• The compressor or fan motor hums but fails to start.
• The fan motor runs slower than usual or does not spin.
• The air conditioner does not blow cold air.
• The capacitor case is visibly swollen, bulging, or leaking fluid.
• A multimeter test shows capacitance is outside the ±5% tolerance range.

Installation Tips

• WARNING: Disconnect all electrical power to the unit before handling or replacing the capacitor.
• Safely discharge the existing capacitor by shorting the terminals with an insulated-handle screwdriver.
• Note or photograph the wire connections to the C, FAN, and HERM terminals before disconnecting.
• Connect the wires to the corresponding terminals on the new capacitor.
• Ensure the capacitor is secured with the original mounting strap or bracket.
• Professional installation is recommended if you are unfamiliar with electrical components.
