• Coordinates cycle timing and sends power to the drive motor, drain pump, and fill valves
• Monitors inputs from the door lock and sensors to manage operation
• Failure can cause the washer not to start, stop mid-cycle, or fail to spin or drain
• Associated with control-related error codes or intermittent operation

• Disconnect power to the appliance before servicing
• Handle the board by the edges and use ESD protection to avoid static damage
• Label or photograph wiring; move connectors to the new board one at a time and verify ribbon-cable orientation
• Mount securely and ensure all harnesses are fully seated before restoring power and running diagnostics per the tech sheet
