Not if you can't reach it.As I said pulling the plug will do that.
In that case the next step is to find a way in to the case but not knowing your mechanical abilities I don't know whether to advise:Ok so I've managed to borrow a multimeter from a friend and checked the supply at the junction box and it reports as 240 v.
I would agree with W here. When you measured this voltage it was presumably across the metal of the contacts in the junction box. At this point I would be checking that the cable coming out of the connections going to the extractor were made correctly. In other words I would take the wires out, examine them and then put them back carefully. A failing bulb can take a fair bit of current, But to fuse the wiring inside the unit sounds a bit extreme and unlikely. It seems much more likely that a poorly made joint failed outside the box.Ok so I've managed to borrow a multimeter from a friend and checked the supply at the junction box and it reports as 240 v.
No I agree but I recently replaced my printer as the repair cost significantly exceeded the cost of a replacement. I don't know the cost of cooker hoods but the cost of getting someone out and the following repair (my option 2) may well be more than the cost of a new appliance. For myself I would have no hesitation of at least opening and looking but seeing the level of difficulty so far, I for one would not like to feel responsible for OP slicing his finger open on the ubiquitous razor sharp edges found in such appliances.I really can’t believe replacement of the entire hood is required because a bulb expired.
