WHIRLPOOL ACCU-BAKE DOUBLE OVEN GONE cRAZY!!? All of the sudden one day the heat just kept rising (700)...

All of the sudden one day the heat just kept rising (700) until adjectives the smoke alarms were beep. We turned it off at the fuse box, turned it rear legs on again, but whenever we try to use it for more than 10 mins it does the freaky "gonna see you in hell" move.

I'm no expert, but I construe the thermostat is blown. Can you tell me if you presume that, too, or whatever else it might be, and how sturdy is it to fix? Where can I order parts?
Damaged concrete...anyway to repair?
Answers:    stop using it and contact current. it might have a warranty
