I ahve a cooktop stove with 4 coil burners, older style. One of the two burner indicator light has failed and probably needs replacing. What I want to know is how to get at the light. The range has a flip up part on top of the stove top that holds the fuses and electricial hook up but is sealed so I can't see the actual lights that need replacing. My question is, must I take the enclosed section apart, held together with screws to get at it, or do these lights and lenses come out from the top I can see. thanks
