Oven interior light does not work, but all other functions are normal.

Safety first: Turn off power before replacing the bulb to avoid electric shock.

• Replace bulb: Remove the glass cover, unscrew the old bulb, and install a new high-temperature oven bulb of the same type and wattage.
• Inspect socket: Check for corrosion or burning at the lamp holder. Replace if damaged.

If a new bulb does not light, test for voltage at the lamp holder (only if you are trained to work with mains voltage) or have a technician inspect the circuit.
