Oven interior light does not work, but the oven heats normally.

Safety first: Turn off power. Ensure the lamp and surrounding area are cool.

Steps:

• Remove the lamp cover and replace the bulb with a new high-temperature oven lamp of the correct type.
• If the new bulb does not light, inspect the lamp holder contacts for corrosion or burning; replace the holder if damaged.
• Check wiring continuity from the holder to the control board or switch.
• If wiring is good, the light switch or relay on the control board may be faulty and the board may need replacement.
