Washer will not run, may show F07 or F7, sometimes associated with heating or motor drive issues on certain models.

Safety first: Disconnect power before removing any panels. Control boards operate at line voltage; do not touch live circuits.

Step-by-step:

• Power cycle: Unplug for 5 minutes, then plug back in and attempt a drain/spin cycle. If F07 reappears immediately, continue.
• Access controls: Remove the top panel to access the main control (CCU). On some models, the motor control (MCU) is mounted near the base or rear.
• Visual inspection: Look for burnt spots, cracked solder joints, or melted relays on both CCU and MCU. A burnt smell is a strong indicator of failure.
• Check harnesses: Verify all connectors between CCU, MCU, and motor are fully seated and not damaged. Reseat each connector one at a time.
• Isolate components: Disconnect the motor harness from the MCU and try powering up. If the error changes or clears, the motor or harness may be shorted.
• Replace faulty board: If a board shows visible damage or testing confirms a stuck relay or short, replace the affected control board with the correct Maytag part number.

Warning: Because this error involves high-voltage control circuits, board-level diagnosis is best left to experienced technicians.
