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

Safety first: Turn off power and ensure the oven is cool. Use gloves to handle glass parts.

• Replace bulb: Remove the glass lamp cover inside the cavity (usually twists off). Replace the bulb with a high-temperature oven lamp of the same wattage and base type specified by Hitachi.
• Inspect lamp holder: Check for discoloration or burning on the lamp socket. Replace the holder if damaged.
• Check lamp fuse: Some models have a separate fuse for the lamp circuit. Test and replace if blown.
