Beko oven shows E16 and interior light does not work; oven otherwise heats normally.

Safety first: Switch off power at the mains before changing the lamp. Glass components may be fragile and hot.

Replace the lamp:

• Remove the glass lamp cover inside the oven (usually twists off counter-clockwise).
• Unscrew the old bulb and inspect the filament; replace with a high-temperature oven-rated bulb of the same type and wattage.
• Inspect the lamp holder for burning or corrosion; replace if damaged.
• If the new bulb does not light, check wiring continuity from the lamp holder back to the PCB.
• If wiring is intact, the lamp control on the PCB may be faulty and the board may need replacement.

Warning: Only use bulbs specifically rated for oven use; standard bulbs will fail quickly and may shatter.
