The control panel shows LOC or a lock icon; the oven will not start, and keys may be unresponsive.

Safety first: This is typically not a hardware failure, but always ensure the oven is cool before working around the control panel.

• Disable control lock: On most BlueStar electronic models, press and hold the designated lock key (often "Lock", "Control Lock", or a key combination such as "Bake" and "Broil") for 3-5 seconds until the LOC indicator clears. Refer to the user manual for the exact sequence.
• Power reset: If the lock will not clear, turn off power at the breaker for 2 minutes, then restore power and try the unlock sequence again.
• Check for stuck key: Press each button several times to ensure that none are physically stuck. Clean the keypad surface with a mild cleaner and a soft cloth.
• Control replacement: If LOC remains and keys are unresponsive despite the correct procedure, the keypad or EOC may be faulty and require replacement.
