Replaces / Cross-Reference Part Numbers

• Replaces any single-value, round motor run capacitor with matching 25 MFD and 370V or 440V specifications.
• A 440V rated capacitor can be used as a direct replacement for a 370V rated capacitor with the same MFD value.
• Compatible replacement for capacitors from brands including Genteq, MARS, Packard, and Aerovox.

Compatibility & Fitment

• Designed for continuous duty in single-phase motor applications.
• Commonly used in HVAC systems, including air conditioner condenser units and heat pumps.
• Suitable for compressor motors and fan motors.
• Also used in pool pumps, refrigerators, furnaces, and other motor-driven equipment.

When to Replace

• Motor hums but fails to start or operates intermittently.
• Fan motor runs slower than normal or requires a manual push to start.
• Compressor does not start, preventing the system from cooling.
• Visible damage to the old capacitor, such as a bulging top, cracks, or fluid leakage.
• Capacitance measures outside the rated 25 MFD ± 5% range when tested with a multimeter.

Installation Tips

• Warning: Disconnect all electrical power to the unit before handling or replacing the capacitor.
• Capacitors can hold a dangerous electrical charge. Safely discharge the old capacitor by shorting across the terminals with an insulated tool.
• Before installing, verify the MFD and voltage ratings of the new capacitor match the requirements of your equipment.
• Note the wire placement on the old capacitor's terminals before disconnecting.
• Ensure the new capacitor is securely mounted and all wire connections are tight.
