If buttons on the key pad are not responding when pressed, it may be possible that the CHILD LOCK feature is active.
To test if the CHILD LOCK feature is deactivated:
Press the STOP/CLEAR button on the microwave's keypad.
- Press and hold the START/ENTER key for approximately 4 seconds until the L indicator or a lock icon appears in the display. If your model's STOP/CLEAR button does not have a lock indicator on it, please refer to your owner's manual to see if your unit has CHILD LOCK and, if so, how to deactivate it.
Press and hold the START/ENTER key again for approximately 4 seconds. The L indicator or lock icon should disappear from the display.
If the controls are still not responding, attempt a reset on the microwave by unplugging the unit for 2-3 minutes. Plug the microwave back in and attempt the use the microwave again. If the controls are still not responding, the microwave will require repair service.
