LG microwave LOC (or Loc) means Control Lock is enabled — the keypad is disabled so buttons cannot be pressed accidentally. This is not a failure code. On LMV2031 and similar over-the-range models, hold the Clear or Stop pad for three seconds until LOC disappears from the display.

Safe to keep using?
No safety issue
This is a status or lock code, not a hardware fault.
How to fix LOC
- Look for LOC or a lock icon on the display — if present, the lock is active.
- Press and hold Clear/Stop (or the pad labeled Lock) for 3 seconds until LOC clears.
- If LOC will not clear, unplug the microwave for 5 minutes and retry the hold sequence.
- Check whether a child-lock setting was enabled in the options menu — some models hide lock under Settings.
- If every pad is dead with no LOC showing, the membrane keypad may have failed — that is a different fault from LOC.
Call a pro when: Call a technician if the keypad stays dead after LOC clears or you smell burning from the control area.
