Recently bought a new house that has an older Frigidaire FES388WGCG electric range. One of the surface indicator lights is not coming on (I suspect it is burnt out). For this model I believe the Part No. 5303297484 is correct. My question is how do I access the area to replace the light? Front panel? Do I have to pull the unit from the wall and are the access screws in the back? Appreciate any help.
