Oven door will not open after a self-clean or high-temperature cycle.

Safety first: Allow the oven to cool completely. Disconnect power before attempting mechanical release.

• Wait for cooldown: Many locks only release below a certain temperature. Ensure the oven is fully cold.
• Manual release: Access the lock mechanism from the top or rear panel. Many Tristar locks have a manual release lever that can be moved to unlock the door.
• Inspect mechanism: Check for bent parts, melted plastic, or grease buildup. Clean and lubricate lightly with high-temperature-safe lubricant if appropriate.
• Replace lock assembly: If the motor or switches are faulty, replace the complete door lock assembly.

After repair, test a lock cycle (if available) to ensure proper operation before using self-clean again.
