Capacitors are critical components in many domestic appliances, providing the phase shift and starting torque that a single-phase motor needs to spin up correctly. When a capacitor weakens or becomes open circuit, the motor may hum, fail to start or run with reduced efficiency. Replacing it with a correctly rated 9µF unit can often restore normal performance without the expense of a new motor or machine.

This universal capacitor is suitable where the original device has the same capacitance value and a compatible voltage rating. Always disconnect the appliance from the mains, discharge the old capacitor safely and double-check all markings before fitting a replacement. If you are unsure about electrical work, seek advice from a qualified engineer.
