How can I take the front panel off the above cooker to replace the grill switch. All screws that I can see have been removed but the panel will not come off. I do not want to force anything as the cooker top is of the ceramic type and is expensive to replace. Do the cooker side panels need to be removed, are there any hidden screws. This is the first time in 55 years that I have failed to take something apart. Looking forward to your reply.
