Oven shows E7 and stops; fan may run but heating is disabled. Often associated with door issues.

Safety first: Disconnect mains power before working around the door mechanism. Beware of sharp metal edges.

• Check door closure: Ensure the oven door closes fully and evenly. Look for bent hinges or obstructions on the door seal.
• Listen for click: Slowly close the door and listen for a distinct click from the door switch. No click may indicate a failed or misaligned switch.
• Access door switch: Remove the top or side panel to reach the door switch assembly near the latch area. On some Clatronic models, the switch is behind the front frame.
• Test switch: Disconnect the switch and test continuity with a multimeter while pressing and releasing the actuator. Replace if it does not change state reliably.
• Inspect latch and lock: For models with an automatic door lock (e.g., pyrolytic cleaning), check the lock motor and linkage for jamming or breakage. Ensure the lock microswitch operates correctly.
• Replace components: Install a new door switch or door lock assembly as required. Adjust the latch position so the door closes firmly and activates the switch.
