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.

  • 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)
