I have a similar problem - all was working well until one of the bulbs blew. However the remaining bulb was working ok. After about 3 months use, the second bulb blew - have replaced both bulbs but they still wont light up. The LED on the front does not light when I press the 'light button'. However the LED for the extractor fan does light when this is selected and the fan still works. Lisa, as far as your problem is concerned, there may be a fuse nearby on a wall socket - perhaps in an adjacent cupboard?
