When to Replace

• Compressor or fan motor hums but will not start.
• Outdoor unit fan is not spinning.
• AC unit is not cooling efficiently.
• Capacitor case is visibly swollen, bulging, or leaking fluid.
• Capacitance measurement is outside the rated ±5% tolerance.

Installation Tips

• Disconnect all electrical power to the HVAC unit before servicing.
• Safely discharge the old capacitor by shorting the terminals with an insulated tool.
• Note the wire positions on the C, FAN, and HERM terminals before removal.
• Connect wires to the corresponding terminals on the new capacitor.
• Secure the capacitor in the mounting bracket to prevent vibration.
