Cooker hood light not working but the fan still runs (all brands)
✅ Safe to check yourself
This is a common, low-risk check most people can do safely. Always unplug the appliance (or isolate power) before touching internal parts.
Quick TipTake a photo of the appliance's model/serial number sticker now — you'll want it if this does end up needing a part or an engineer.
Because the light and fan on a cooker hood run on largely separate circuits, a dead light with a working fan is almost always just a bulb, and one of the most straightforward fixes on this entire site.
What to check first
- Check what type of bulb your hood uses — many older hoods use small halogen G4 bulbs, while most newer ones use integrated LED strips or standard small-screw/bayonet bulbs; your manual or a look inside the light housing will confirm which.
- With the hood switched off at the wall (not just the light switch), check whether the bulb has visibly blown (a halogen bulb often shows a grey/black mark, an LED strip may have a visibly dead section).
- Replace the bulb — always match the exact wattage and fitting type specified for your model, as cooker hood light fittings are often rated for a specific low wattage due to limited heat clearance.
- If yours has an integrated (non-replaceable) LED strip rather than a swappable bulb, a dead light usually does mean the whole light unit needs replacing rather than just a bulb.
When to call an engineer
If a fresh, correctly-rated bulb doesn’t fix it, the light’s wiring or switch may be at fault — this is straightforward for an electrician or appliance engineer to check, but isn’t worth risking yourself if it means accessing wiring behind the light housing.
