Oven interior light not working, oven otherwise functions normally

Safety first: Switch off power before changing the bulb to avoid shock and burns.

Step-by-step checks:

• 1. Replace bulb: Remove the glass cover (usually twists off) and fit a new high-temperature Zanussi-compatible oven bulb of the same wattage and cap type.
• 2. Inspect lamp holder: Check for signs of burning or loose contacts. Replace the lamp holder if damaged.
• 3. Check wiring: If a new bulb does not work, inspect the wiring from the lamp to the control board or switch.
• 4. Test lamp relay/switch: On electronic models, the lamp is controlled by a relay on the PCB. If no voltage reaches the lamp, the relay or PCB may need replacement.

Warning: Ensure the glass cover is refitted securely to protect the bulb from splashes and heat.
