The oven is a double wall electric oven. The upper oven set bake switch burned out therefore the switch and knob were replaced. After replacement the bake coil will not heat. The coil was checked and appears to be ok. He even moved the bottom bake coil to the top oven. The coil would not heat. Could the replaced switch be bad or could the wrong switch have been installed? The broil coil works ok.
This service man has been back twice and I have someone else scheduled for this week.
Thanks
