How to take a grill control knob off a belling cooker?

i looked at a photo of that oven you have, it looks something like mine,, but mine is a different make...(BUT) if you open the top oven door, and look up to the side frame of the oven door, there should be 2 screws, holding the knob control pannel in place, , take all the knobs off first, if there is screws there,, unscrew them , and work the control pannell bit by bit, have all the power (OFF) going to the cooker,
