I have a Coppertone Hotpoint double wall oven and I understand they were made by GE. It looks just like the GE above but it is 24" wide. The bake element in the upper over started sparking and died. I replaced it but now the knob indicator light doesn't come on and the element doesn't either. Anyone have any ideas? I've been told it could be the thermostat. Does anyone know if that requires a new part? Any help would be greatly appreciated.
