Compatibility & Fitment

• Air conditioners
• Heat pumps
• Compressors
• Refrigeration units

When to Replace

• The motor hums but fails to start or turn.
• The motor starts slowly or requires manual assistance.
• The circuit breaker trips when the motor attempts to start.
• The capacitor case is visibly bulged, cracked, or leaking fluid.

Installation Tips

• Disconnect all electrical power from the equipment before beginning work.
• Safely discharge the existing capacitor by shorting its terminals with an insulated tool, such as a screwdriver with a plastic handle.
• Confirm the new capacitor's specifications match the original. The capacitance (µF/MFD) should be the same. The voltage (VAC) rating must be equal to or higher than the original part.
• Connect wires to the new capacitor terminals securely. Polarity is not a concern for AC start capacitors.
