I have a Frigidaire Gallery Electric Stove with the glass top. The top burners work fine. The oven however is not working. I was told it was the electronic control panel in the back on top. I have the one with the high back controls. The instrument panel is in there. The cost is $300 plus $100 for labor. Is there more to those than just popping the old one out and putting the new one in? If I could save the labor cost by doing it myself that would be a plus.
