Customer Questions and Answers for Sensor Assembly by Lg

Phillip, the error LE can be caused by a loose wire connector, a broken wire, a failed stator winding or hall sensor 4417EA1002Y, or even a failed main control board EBR78534502. With the rotor removed, the stator windings can be tested for resistance and should measure between 5 to 15O when each of the three terminals are tested to the others. If the windings test good, the hall sensor can be tested for incoming voltage by turning the washer on (do not start a cycle) and testing from the white wire (red meter probe) to the gray wire (black meter probe) for 10-15VDC. If the voltage is there, the main control is sending voltage so the washer would need to be turned off, rotor placed back on, and the main control accessed for further testing. Once the main control is accessed, there will be a four wire connector with a grey wire, red wire, white wire, and blue wire. With the black meter probe placed on the grey wire, the washer will need to be turned on and the red probe placed at the red wire. While rotating the spin basket by hand, there should be a 10VDC voltage shown. The red probe would then be moved to the blue wire for the same test results. If there is not a return voltage shown at either the red or blue wire, the hall sensor has failed. If there is a return voltage, the main control has failed.
