Component test · WasherDirect-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.
Guide · WasherMaytag Neptune front-loaders sold roughly 1997-2004 were the subject of US and Canadian class actions over doors, circuit boards and mold; Maytag settled (US estimate around $18.5 million) and those claim windows are closed. Technicians repeatedly report a pattern: the door lock wax motor degrades and its changing resistance damages the lock-drive components on the control board, so replacing only the board brings the failure back.
Guide · WasherLE 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.
