How to Fix / Troubleshooting

Safety First: Unplug the microwave if it starts functions on its own to prevent unintended operation.

  • Dry out panel: If this occurs after heavy cooking or cleaning, unplug the unit and allow the control panel area to dry for several hours.
  • Clean keypad: Wipe the keypad with a dry, soft cloth. Avoid spraying cleaners directly on the panel.
  • Inspect gasket: Check for gaps around the control panel where steam could enter. Reseal or replace trim as needed.
  • Replace keypad/UI: If random beeping continues, replace the membrane keypad or user interface board.
