Start Capacitor
The start capacitor provides the phase-shifted electrical pulse required to initiate rotor rotation in single-phase induction motors. When the capacitor fails due to dielectric breakdown or electrolyte leakage, the motor receives power to the windings but cannot overcome inertia, resulting in a 60Hz electromagnetic hum. Replacing this component restores the necessary torque to start the motor.

Impeller
Debris ingestion or calcium scale buildup within the pump housing can physically wedge the impeller against the diffuser. This mechanical seizure prevents the rotor from spinning despite the magnetic field being present, causing a stall hum. If the impeller is damaged or structurally compromised by the obstruction, replacement is necessary to restore clearance and flow.

Shaft Seal Assembly
A compromised shaft seal allows chlorinated water to reach the motor bearings, leading to oxidative corrosion and increased friction. This increased mechanical resistance can prevent the motor from reaching the RPM threshold required to disengage the start circuit. Replacing the seal is essential whenever the pump housing is opened to address a seized or stalled impeller condition.
