Interior light not working but refrigerator otherwise cools normally.

Safety first: Unplug before replacing bulbs or LED modules.

Step-by-step checks:

• 1. Replace bulb: On models with replaceable bulbs, remove the light cover and fit a new bulb of the correct type and wattage.
• 2. Check door switch: Press the door switch; if the light flickers or never comes on, the switch may be faulty.
• 3. LED modules: On LED-lit models, the entire module may need replacement if it has failed; use the correct Indesit part.

When to call a technician: If a new bulb or module does not work, wiring or PCB faults may be present.
