Washer motor control unit / inverter board

Direct-drive and inverter washers use a motor control unit (MCU) that powers a 3-phase motor and reads a hall sensor or tach. Separate MCU, motor windings, hall sensor and harness before buying a board.

LG LE code: testing the hall sensor and stator

LE means the board drove the motor but did not see rotation. Check the harness, then test the hall sensor (about 10 kΩ per channel and a pulsing signal), then the stator windings, before condemning the board.

Hall sensor and tach generator (motor speed feedback)

Hall sensors are 3-wire devices (supply, ground, signal) that switch as magnets pass; tach generators are 2-wire coils that make a small AC voltage as the motor turns. Test the right way for the type.
