Replaces / Cross-Reference Part Numbers

• Replaces any round or oval dual run capacitor with matching 45/5 uF capacitance and 370V or 440V specifications.
• Always verify capacitance, voltage, and physical dimensions before purchasing.

Compatibility & Fitment

• Designed for HVAC applications including air conditioners, heat pumps, and condenser units.
• Combines two capacitors into one unit to run a compressor motor and a fan motor simultaneously.
• Three terminals are labeled: HERM (for compressor), FAN (for fan), and C (common line).

When to Replace

• The outdoor unit's fan is not spinning or turns slowly.
• The compressor fails to start or struggles to turn on.
• The A/C unit produces a humming or buzzing noise but does not start.
• The existing capacitor case is visibly swollen, bulging, or leaking oily fluid.

Installation Tips

• Disconnect all electrical power to the unit before performing service.
• Safely discharge the existing capacitor by shorting across the terminals with an insulated screwdriver.
• Note or photograph the wire connections to the C, HERM, and FAN terminals before removal.
• Connect the wires to the corresponding terminals on the new capacitor.
• Secure the new capacitor with the mounting strap or bracket.
