Known issue: Maytag Neptune front-loader door lock and control board failures
Maytag 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.
