• AMRAD USA2030

Compatibility & Fitment

• Designed for continuous duty in single-phase AC motor run applications.
• Used in air conditioners, heat pumps, compressors, furnaces, and fan motors.
• The physical dimensions must match the mounting bracket of the existing equipment.

When to Replace

• Motor hums but does not start.
• Motor starts or runs slowly.
• Fan blades require a manual push to start spinning.
• Visible signs of damage, such as a bulging top, cracks, or fluid leaks.
• Capacitance measures outside the ±5% tolerance when tested with a multimeter.

Installation Tips

• Disconnect all electrical power to the appliance before installation.
• Safely discharge the old capacitor by shorting the terminals with a resistor or insulated screwdriver.
• Ensure the new capacitor's uF (MFD) rating matches the original specification exactly.
• Using a capacitor with an equal or higher VAC rating is acceptable. Do not use one with a lower VAC rating.
• Note the wire placement on the old capacitor's terminals before disconnecting.
