Steam or moisture appears on the control panel or between door glass panes during cooking.

Safety first: Avoid touching hot glass. Allow the oven to cool before inspection.

Step-by-step checks:

• 1. Check vents: Ensure the top and front ventilation slots are not blocked by trim or objects.
• 2. Inspect door seal: Replace a worn door gasket to reduce steam escape.
• 3. Door glass tightness: Tighten screws holding the inner glass to prevent steam ingress between panes.
• 4. Use extraction: Run a cooker hood or open a window when cooking high-moisture foods.
