My Whirlpool gas oven/cooktop suffered a power surge after my home was hit by lightening. I lost a bunch of GFI's, a dimmer and my garage door opener during the strike. My gas stove top is still working but the oven is not. Oddly enough the oven light stays on. None of the touch keys work. The display just shows jibberish and changes whenever I light a different burner. I'd like to think the repair is a s simple as replacing a circuit board but there are several different ones and they are pricey. Can anyone help me narrow down which one to replace.
