Morphy Richards oven shows E16 and the interior light does not work, though heating is normal.

Safety first: Switch off power and allow the lamp area to cool before touching.

Steps:

• Replace bulb: Remove the glass lamp cover inside the oven (usually twists off). Replace the bulb with the correct high-temperature oven lamp (typically 25–40 W, E14 base) specified by Morphy Richards.
• Inspect lamp holder: Check for heat damage or corrosion on the lamp holder contacts.
• Test continuity: If a new bulb does not work, test the lamp holder and wiring for continuity back to the control board.
• Control fault: If wiring and holder are good, the light relay or switch on the electronic control board may have failed and the board may need replacement.

Note: Always use oven-rated bulbs; standard bulbs will fail quickly.
