Pyrolytic self-clean cycle does not start; oven beeps and returns to normal mode.

Safety first: Ensure the oven is empty and cool before attempting self-clean.

• Check door lock: Start a self-clean cycle and listen for the lock motor. If the door does not lock, inspect the lock mechanism and door alignment.
• Verify safety thermostats: Test high-limit thermostats for continuity. Replace any that are open.
• Follow user instructions: Remove all racks and accessories if required by the manual. Ensure the door is fully closed and latched.
• Reset control: Turn off power for 5 minutes, then retry. If self-clean still will not start, further diagnosis of the lock and control board is needed.
