You may have an open neutral (center) wire in your 220V (or 240V) wall outlet (or where the wires go into your range). Your Electronic Oven Control (EOC) and light bulbs operate off of 120V, which it gets from one leg of your 240V outlet to neutral. You surface elements don't use the EOC, but are directly connected (when on) to both legs of your 240V Power. So unplug your range, and remove the access panel to your electrical connections at the bottom back of your range. Make sure the center screw that the white wire is connected to is tight. If that's okay, then the problem is probably in your electrical wall outlet, and you should contact an electrician to check it and fix it.
