Likely causes

  • CommonControl lock feature intentionally or accidentally engagedMost microwaves include a child-safety lock, often engaged by holding a specific button.
  • CommonWrong button or hold duration attempted for unlockingUnlock sequences differ significantly across brands and models.
  • Less commonControl board glitch keeping the lock engagedRarely, a reset is needed to clear a stuck lock state.

What to do

  1. Look for a 'Lock,' 'Child Lock,' or padlock icon button on your specific model.
  2. Press and hold that button for the duration specified in your manual, often around 3 seconds, since a quick tap usually won't release it.
  3. Watch the display for the lock icon or message to clear.
  4. If you don't have the manual, search your exact model number online for the specific unlock steps.
  5. If the correct button and hold time doesn't work, unplug the microwave for about a minute and try again after restoring power.
  6. If the lock still won't release after a proper attempt and a power reset, the control board may need professional service.

When to call a pro

If the correct unlock sequence and a power reset don't clear it, an appliance technician can check the control board.
