Oven interior light does not work, but heating and other functions are normal.

Safety first: Switch off power or at least ensure the oven is off and cool before changing the bulb.

Bulb replacement:

• Remove the glass lamp cover by twisting or unclipping it according to the manual.
• Unscrew or pull out the old bulb.
• Install a new high-temperature oven bulb of the same type and wattage (check Liebherr specifications).
• Refit the glass cover securely.

If the new bulb does not light, inspect the lamp holder and wiring for damage and replace the holder if necessary.
