Replaces / Cross-Reference Part Numbers

• This capacitor replaces any round, single-capacitance 30 uF capacitor with a voltage rating of either 370V or 440V.
• Always match the microfarad (uF/MFD) rating.
• The replacement capacitor's voltage rating must be equal to or greater than the original capacitor.

Compatibility & Fitment

• Commonly used for HVAC systems, air conditioner compressors, heat pumps, fan motors, and other electric motor applications.
• The round shape and standard terminal configuration allow for wide compatibility with units from multiple manufacturers.
• Verify physical dimensions (diameter and height) to ensure a proper fit within the existing mounting bracket and space.

When to Replace

• The motor hums but fails to start or struggles to start.
• The fan or compressor runs intermittently or at a reduced speed.
• The top of the existing capacitor is swollen or bulging.
• Fluid is leaking from the capacitor casing.
• A multimeter test shows the capacitance is outside the specified tolerance range.

Installation Tips

• Disconnect all electrical power to the equipment before beginning work.
• Safely discharge the old capacitor by shorting the terminals with an insulated-handle screwdriver.
• Note the wire placement on the old capacitor terminals before disconnecting. Taking a picture is recommended.
• Connect the wires to the corresponding terminals on the new capacitor.
• Secure the new capacitor with the original mounting strap or bracket.
