Drain Pump Motor
The washer's control logic requires the tub to be empty before the high-speed spin sequence begins. If the drain pump motor fails or the impeller is obstructed, the pressure transducer will report a water level that inhibits the spin cycle to prevent mechanical overload. Replacing this centrifugal motor unit restores the machine's ability to evacuate water and proceed to the spin phase.

Rotor Position Sensor (Hall Sensor)
In LG's Direct Drive system, the Hall Sensor monitors the precise orientation and velocity of the rotor. If the sensor's internal circuitry fails, the Main PCB cannot accurately synchronize the stator's magnetic fields, causing the motor to stall or shake instead of spinning. Replacing this discrete electronic component restores the tachometer feedback loop required for high-speed rotation.

Door Lock & Switch Assembly
For operator safety, high-speed drum rotation is physically inhibited unless the door latch confirms a secure mechanical lock. If the internal solenoid or microswitch within the assembly fails, the logic board will not receive the 'locked' signal and will abort the spin cycle. This assembly replacement ensures the safety interlock circuit is properly closed during the spin request.
