switch the power off. Remove the 4 screws holding the fan cover inside the oven. Remove the fan cover. Remove the fan blade by undoing the centre nut (its a left hand thread). Now at the back of the oven remove the two screws holding the back panel and remove it, you may want to remove the screws holding the mains cable to give you some slack. The motor is removed by twisting it anticlockwise after bending the small metal tab that stops it being moved.
