Oven interior light does not work but all heating functions are normal.

Safety: Switch off power before changing the bulb to avoid electric shock.

• Replace bulb: Remove the glass cover and fit a new high-temperature oven bulb of the correct type.
• Inspect holder: If the new bulb does not work, inspect the lamp holder for corrosion or burning. Replace the holder if damaged.
• Check wiring: Ensure the lamp wiring is intact and firmly connected.
