What Does Error LOC Mean?
The LG oven LOC error code indicates that the control lock function is engaged, preventing normal operation. When this error appears, the oven will not respond to button presses, and the control panel will display a locked icon. This is typically caused by the Control Lock or Child Lock feature being activated, often due to accidental activation from a stuck button or unintended key press.
Common Symptoms:
- Oven displays 'LOC' on the control panel and will not start cooking cycles or respond to button presses
- Control panel buttons are unresponsive until lock is deactivated
Possible Causes
- Control Lock / Child Lock feature is activated (medium)
- Accidental activation due to stuck button or unintended key press (medium)
