its a bit involved to get the timer out of these.
two 'L' shaped plastic bits prise off the ends of the control panel.under there are screw to release the top edge of the control panel.undo the grill door and under the bottom edge of the control panel is 3 screw.this will then allow you to pull the control panel forward.depends now if the clock is mounted separate or built in to the control.if it is the later you have to remove all the control knobs and drop it out of the back.Not a job for the faint of heart!!!
