Replaces / Cross-Reference Part Numbers

• Replaces any round dual run capacitor with matching 30/5 MFD and 370V or 440V specifications.
• Amrad Engineering: USA2226
• Part Number: 331441

Compatibility & Fitment

• For use in HVAC systems, central air conditioners, heat pumps, and condensing units.
• Powers both a compressor motor and a fan motor from a single component.
• To ensure fitment, verify that your system's required specifications match this capacitor's MFD rating (30/5), voltage (370V or 440V), and physical shape (round).

When to Replace

• Compressor or fan motor fails to start or experiences a hard start.
• A humming noise is heard from the unit, but the motor does not engage.
• The air conditioner unit is running but blows warm air.
• The capacitor case is physically swollen, bulging at the top, or leaking fluid.

Installation Tips

• Disconnect all electrical power to the HVAC unit before servicing.
• Safely discharge the existing capacitor to avoid risk of electric shock.
• Note the wire placement on the old capacitor's terminals (C, FAN, HERM) before disconnecting.
• Connect wires to the corresponding terminals on the new capacitor.
• Ensure the capacitor is securely mounted within the unit's housing.
