Replaces / Cross-Reference Part Numbers

• This capacitor replaces any round 30/5 uF 370V or 440V dual run capacitor. While this is not an exhaustive list, it is a direct replacement for part numbers including: 97F9833, C3305R, C4305R, P291-3054R, TRCFD305, USA2227, and CBB65.

Compatibility & Fitment

• Used in air conditioning units, heat pumps, condensers, and other HVAC systems to start and run a compressor motor (30 uF) and a fan motor (5 uF) simultaneously.
• To ensure compatibility, match the specifications of your original capacitor:
• Capacitance: Must be 30+5 uF/MFD.
• Voltage: Must be 370V or 440V. This 440V capacitor can safely replace a 370V capacitor.
• Shape & Size: Must be a round capacitor with similar dimensions to fit the mounting bracket.

When to Replace

• Your outdoor unit hums but the fan does not spin or the compressor will not start.
• The fan or compressor motor starts slowly or not at all.
• The original capacitor shows physical damage, such as a bulging top, swelling, or fluid leaks.

Installation Tips

• Disconnect all electrical power to the HVAC unit before handling.
• Safely discharge the existing capacitor by shorting across the terminals with an insulated screwdriver.
• Take a picture or note the wire placement on the C, FAN, and HERM terminals before disconnecting.
• Connect the new capacitor by matching the wires to the corresponding terminals.
