Pyrolytic self-cleaning does not start; oven appears to work normally otherwise, no code

Safety: Pyrolysis reaches extreme temperatures; do not attempt to bypass safety systems.

• Check door lock: Start a pyrolytic cycle and listen for the lock motor. If the door does not lock, inspect and test the door lock assembly.
• Verify door seal: Ensure the gasket is intact; some models will not start pyrolysis if the seal is badly damaged.
• Test pyro sensor: If accessible, measure the dedicated pyrolytic sensor and replace if faulty.
• Control reset: Disconnect power for 15 minutes and retry. Persistent failure may require control board diagnostics.
