Motor Start Capacitor
The start capacitor is responsible for creating the rotational torque required to initiate motor movement. When the dielectric material inside the capacitor degrades, the motor cannot overcome the stationary inertia of the wet-end assembly, resulting in an audible electromagnetic hum without shaft rotation.

Pump Impeller
Debris bypass or mineral scaling can lodge between the impeller vanes and the diffuser shroud. This mechanical obstruction physically locks the motor shaft; the humming sound is the result of the motor windings being energized while the rotor is in a stalled or 'locked rotor' state.

Motor Seal and Gasket Rebuild Kit
A compromised shaft seal allows chlorinated water to reach the motor bearings, causing oxidation and eventual seizure. Replacing the seals is necessary when clearing a jammed impeller to prevent moisture from entering the motor housing and causing further electromechanical failure.
