Could a failing Motor Hall Effect Sensor cause the LG WM3900HWA to have symptom: Wont Spin Le Error?

The Hall Effect sensor monitors the magnetic field of the rotor to provide RPM and position data to the control board. Mechanical vibrations and thermal cycling cause micro-fractures in the sensor's internal circuitry, leading to a loss of signal. Without this feedback, the machine's controller cannot verify motor movement and triggers the LE error to prevent stator overheating.

Could a failing Wiring Harness (Stator to PCB) cause the LG WM3900HWA to have symptom: Wont Spin Le Error?

Vibration fatigue at the connector housing on the stator can lead to pins backing out or wire fatigue. This breaks the continuity of the low-voltage DC signal required for the position sensor, simulating a motor lock-up.

Could a failing Stator Assembly cause the LG WM3900HWA to have symptom: Wont Spin Le Error?

While rare, an internal open circuit in one of the three copper windings will prevent the motor from achieving enough torque to overcome the inertia of the drum. This prevents the initial 'kick' required for rotation, resulting in the LE error.
