whirlpool oven GBS277PDQ6 gold line

We had a lightning storm last night and, after a close by strike, the oven display went blank and all of the keys are unresponsive. The fan kicked on immediatly after the strike and will not shut off. I have reset the breaker, but the oven will not respond. Do I need a new micro computer or solenoid or is there an internal fuse? Is this older oven worth fixing? Thanks in advance for your help!
