LG Oven: controls locked
What is this symptom?
If your LG oven's control panel is unresponsive and displays a lock indication like 'LOC' or a padlock icon, you may have accidentally activated the control lock or child lock feature. This commonly happens after using the self-cleaning cycle. Unfortunately, without unlocking the controls, you won't be able to adjust settings or start cooking.
Possible Causes
Control Lock/Child Lock feature is activated
How to Identify: A padlock icon or "LOC" message appears on the display and buttons do not respond to presses.
Part: Control panel lock function
