Oven light does not work, but all heating and fan functions are normal.

Safety first: Switch off power at the breaker and allow the oven to cool before changing the lamp.

Step-by-step checks:

• Replace lamp: Unscrew or unclip the glass lamp cover inside the cavity. Replace the bulb with the exact type and wattage specified by V-ZUG (high-temperature oven lamp).
• Inspect lamp holder: Check for corrosion or burning on the contacts. Clean lightly or replace the lamp holder if damaged.
• Check seal: Ensure the glass cover and gasket are properly seated to prevent moisture ingress.

When to call a technician: If a new lamp does not work, the lamp circuit on the control board may be faulty and should be checked by a technician.
