Magic Chef oven display shows LOC or a lock icon; oven will not start or change settings.

Safety note: This is usually not a hardware failure but a feature. No need to disconnect power unless keys are unresponsive.

• Disable control lock: On many Magic Chef ovens, press and hold the Lock or Clock button for 3–5 seconds until LOC disappears. Check your user manual for the exact key combination.
• Power reset: If LOC will not clear, turn off the breaker for 5 minutes, then restore power and try again.
• Check keypad function: If some keys do not respond, the keypad may be failing. Inspect and possibly replace the membrane keypad / control panel.

When to call a technician: If the lock indicator will not clear and keys are non-functional, professional diagnosis of the keypad and EOC is recommended.
