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

Safety first: Disconnect power. The glass cover and bulb may still be hot; allow to cool.

Step-by-step checks:

• 1. Replace bulb: Unscrew the glass lamp cover inside the oven. Remove the bulb and replace with a high-temperature Hotpoint-Ariston-compatible oven bulb of the same wattage and cap type.
• 2. Inspect lamp holder: Check for signs of burning or cracking. If damaged, replace the lamp holder assembly.
• 3. Check wiring: From the rear, inspect the lamp wiring for heat damage. Repair or replace as needed.
• 4. Control issue: If a new bulb and holder do not work, the lamp relay or control output may have failed, requiring control board replacement.
