The display shows 'LOC' or a lock icon; the oven will not start, and buttons may be unresponsive.

Safety First: No internal repair is needed for this feature; do not disassemble the oven for a LOC indication alone.

• Disable control lock: On most Thor Kitchen ovens, press and hold the Lock or Control Lock key for 3-5 seconds until the LOC indicator disappears. Refer to the user manual for the exact key combination.
• Power reset: If the lock will not clear, turn off the breaker for 1-2 minutes, then restore power and attempt to disable the lock again.
• Check keypad function: If the lock key does not respond but other keys do, the touchpad/control panel may be failing and require replacement.
• Service if persistent: If 'LOC' remains on the display and no key combination clears it, the electronic oven control board may be stuck in lock mode and should be evaluated or replaced by a technician.
