Our neighbor’s tree was hit by lightning, and it shorted out our oven’s electronic control panel. The stove works, and the oven light comes on, but the panel display is blank. Assuming the worst, that I have to replace the entire control panel, about how much will that cost? I have an appliance repair guy coming out to look at it, but I don’t want to get ripped off. The oven is a pretty new Frigidaire (but not under warranty).
