I am trying to replace the timer on a Lamona HJA3650 oven (think its a Howdens make). The problem is that to remove the timer you need to remove the stainless steel fascia and I cannot see how its held on. Taking the two rotary knobs off do NOT reveal any screws and I cannot see any screws holding the fascia on. I spent an hour today trying to accomplish this with no success. Has anyone else had this problem and can anyone help shed some light on the issue please?
