Replaces / Cross-Reference Part Numbers

• Serves as a universal replacement for capacitors with matching 40/7.5 MFD and 370V or 440V specifications.
• Compatible with parts from multiple brands including Packard TRCFD4075, Genteq, Amrad USA2235, and others.
• Always verify capacitance (MFD), voltage (VAC), and physical dimensions before ordering.

Compatibility & Fitment

• Designed for HVAC systems, including central air conditioners and heat pumps.
• Simultaneously powers a compressor motor (40 MFD) and a fan motor (7.5 MFD) in outdoor condenser units.
• Suitable for single-phase AC motor run applications requiring a dual capacitor.
• Confirm physical dimensions (diameter and height) for proper fit within the unit's mounting bracket.

When to Replace

• Outdoor unit fan is not spinning or turns slowly.
• Compressor hums but fails to start.
• Air conditioner blows warm air.
• Visible signs of capacitor failure such as a swollen or bulging top, leaking fluid, or heavy corrosion.
• Capacitance measures outside the rated tolerance when tested with a multimeter.

Installation Tips

• WARNING: Stored electrical charge can cause severe shock. Disconnect all power to the HVAC unit at the breaker and service disconnect before handling.
• Safely discharge the existing capacitor by carefully shorting across the terminals with an insulated-handle screwdriver.
• Document or photograph the wire placement on the old capacitor's terminals (C, H, F) before disconnecting.
• Connect the wires to the corresponding terminals on the new capacitor.
• Secure the new capacitor in the mounting strap to prevent vibration damage.
