Replaces / Cross-Reference Part Numbers

• Replaces any brand of oval-shaped run capacitor with matching 10 µF/MFD capacitance and 370V or 440V AC voltage ratings.
• Ensure physical dimensions (height and width) are compatible with your equipment's mounting bracket.

Compatibility & Fitment

• Designed for continuous duty in single-phase motor run applications.
• Commonly used for compressor and fan motors in air conditioners, heat pumps, refrigerators, and other HVAC systems.
• The dual 370/440V rating allows for use in both 370V and 440V applications.

When to Replace

• Motor struggles to start, makes a humming noise, or will not start.
• Fan motor requires a manual push to start spinning.
• The capacitor housing is visibly swollen, cracked, or leaking fluid.
• Measured capacitance is outside the specified ±5% tolerance range.

Installation Tips

• Disconnect all electrical power to the equipment before beginning work.
• Safely discharge the existing capacitor by shorting across the terminals with an insulated-handle tool.
• Verify the µF (MFD) rating matches the original capacitor. The voltage rating of the replacement can be equal to or higher than the original, but not lower.
• Note the wire placement on the old capacitor terminals before disconnecting. Replicate the connections on the new capacitor. AC capacitors are not polarized.
• Secure the new capacitor with the original mounting hardware.
