Hall sensors in LG washing machines are electronic components that detect the position and speed of the motor. They operate on the Hall effect, where a voltage difference is produced across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. A faulty hall sensor disrupts the communication between the motor and the control board, potentially causing the washing machine to malfunction. Symptoms of this malfunction include error codes related to motor speed, failure to start a wash cycle, or erratic drum movement.
The reliable operation of these sensors is critical for the proper functioning of the washing machine’s motor control system, and by extension, the overall appliance. Historically, improvements in sensor technology have aimed to enhance accuracy and durability. However, the operating environment within a washing machine presents challenges to the longevity of these devices.
