Oven door does not close fully or sits crooked; heat escapes around the door; no error code.

Safety first: Ensure the oven is cool before adjusting the door.

Step-by-step checks:

• Inspect hinges: Open the door fully and check for play or sagging. Tighten hinge mounting screws on the door and oven frame.
• Check seal: Examine the door gasket for hard, flattened, or torn sections. Replace the seal if it does not spring back when pressed.
• Adjust door: On some V-ZUG models, hinge position can be adjusted slightly. Loosen mounting screws, realign the door, and retighten.
• Replace hinges: If the door still does not close evenly, replace both hinges as a pair with the correct V-ZUG parts.

When to call a technician: If the oven frame itself is warped, professional assessment is required.
