Display shows LOC or a lock icon; oven controls do not respond, but time may still display.

Safety first: This is a user setting, not a hardware failure.

• Disable control lock: On most LG Studio ovens, press and hold the Lock or Clear/Off key for 3–5 seconds until the LOC indicator disappears. Refer to your user manual for the exact key combination.
• Test controls: Try setting a bake temperature to confirm normal operation.
• Power reset if needed: If LOC will not clear, turn the breaker OFF for 1 minute, then ON, and try again.

Note: If the lock indicator will not clear even after a reset, there may be a control board or keypad issue.
