FAQs

A failing start capacitor typically manifests as a motor that hums or buzzes but fails to spin up, or one that struggles to reach full speed. You may also notice the motor tripping the circuit breaker immediately upon startup or overheating due to the inability to overcome initial inertia.
No. This is a dry, electrolytic, non-polarized capacitor designed specifically for intermittent duty in AC motor starting circuits. It is intended only to provide the necessary torque to get the motor moving and should be disconnected by the centrifugal switch once the motor reaches approximately 75% of its rated speed.
You can replace a capacitor with one that has a higher voltage rating (e.g., using a 330V capacitor in place of a 250V one), but you should never use a capacitor with a lower voltage rating than the original. The capacitance (uF/MFD) must match the original specification within the manufacturer's tolerance range.
Always disconnect the power supply to the equipment before beginning work. Because capacitors store electrical energy even when the power is off, you must discharge the old capacitor by placing an insulated screwdriver across the terminals before touching them to prevent a dangerous electrical shock.
No. This is a non-polarized capacitor, meaning it does not have a positive or negative terminal. You can connect the wires to either terminal without affecting the performance of the motor.
The lifespan depends heavily on the frequency of starts and the operating environment. Excessive heat, frequent rapid cycling, and voltage spikes are the primary causes of premature failure. If your motor is starting frequently, ensure the capacitor is kept in a cool, ventilated area to maximize its service life.
