• Tolerance: ±6%
• Voltage Rating: 370V or 440V AC
• Frequency: 50/60 Hz
• Shape: Round
• Terminals: 3 (HERM, FAN, C)
• Operating Temperature: -40°C to +70°C
• Construction: Metal case, oil-filled

Replaces / Cross-Reference Part Numbers

• Replaces any dual run round capacitor with matching 35/3 MFD capacitance and 370 VAC or 440 VAC voltage ratings. The physical dimensions should also be compatible with the mounting bracket.

Compatibility & Fitment

• Used in HVAC systems, air conditioners, heat pumps, and furnaces.
• Powers a compressor motor (HERM) and a fan motor (FAN) simultaneously.
• Verify the MFD rating, voltage, and physical size of your original capacitor before ordering. A capacitor with a 440V rating can replace one with a 370V rating, but not vice-versa.

When to Replace

• Motor hums but does not start.
• Fan or compressor struggles to start or runs slowly.
• AC unit is not cooling effectively.
• Visible signs of failure on the old capacitor, such as a swollen or bulging top, or leaking fluid.

Installation Tips

• Disconnect all electrical power to the unit before servicing.
• Safely discharge the existing capacitor by shorting the terminals with an insulated-handle screwdriver.
• Photograph or make a note of the wire connections before disconnecting them.
• Connect wires to the correct terminals: 'HERM' for the compressor, 'FAN' for the fan motor, and 'C' for the common line.
