on both cooker side panels at the front door edge you will see metal cover strips.prise these off with a screwdriver and you will see screws.remove these screws and then remove the ones on the back edge.pull side panel off.it will be wedged under hob side but keep pulling and it will come away.do this on both side panel and then you will see the 4 mounting screws for the hob.remove them and lift hob up carefully.

model details would be helpful but general rule of thumb energy regulator faulty or hotplate blown
