We've trying to take out heating spiral in the oven,but we didn't unplug the stove and short circuit happened.can we fix it by ourself?

I assume you are talking about an electric stove,and you were trying to take out the--electric spiral-- by this i think you are refering to the oven or burner element,you must have blown a fuse or breaker,older houses carry fuse newer ones use breakers they do the same thing,disconnect the power from the appliance whenever there is a short or a over load,a fuse usually need to be replaced, while a breaker can be reset, be careful electricity can cause property and personal damage it can also kill you.
