Microwave interior light does not come on, but the unit heats and operates normally.

Safety first: Unplug the microwave. Lamps may be hot immediately after use.

• Step 1 – Access lamp: On many Severin models, the lamp is accessible by removing the outer cabinet or a small cover near the side or top.
• Step 2 – Inspect bulb: Check if the filament is broken or the bulb is darkened. Replace with the correct type and wattage specified by Severin (often a special microwave-rated bulb).
• Step 3 – Check socket and wiring: Ensure the lamp holder contacts are clean and that wires are firmly connected.
• Step 4 – Test: Reassemble and test. If the new bulb does not light, the lamp circuit on the control PCB may be faulty and require service.
