Macguyvering is one of the best activities in life.
I remember having "fixed" an electric kitchen. Well...
A friend had tried to use the electric kitchen in a rented apartment to heat up the pitcher of an electric kettle. Bad idea, the bottom of the thing melted down and released "a lot" of water on the kitchen. Power out. It wouldn't work anymore. We let it settle for a whole day, but it wouldn't work anymore anyway, and we were hungry with just raw meat to eat.
So, I shut the power down (water and electricity... you know...), unscrewed the kitchen with a table knife (in the dark), held it open with two bog rolls and two forks, turned the power on again and dried the thing up with a hairdrier.
It worked like a charm, though it's not exactly a "fixing".
