If it keeps tripping the main fuse when you plug it in, doesn't that tell you something, like, your fridge has a fault, to keep plugging it in isn't going to solve the problem, something you haven't yet grasped. The fuse blows to save people from being electrocuted. Get it checked by a qualified electrician or buy a new fridge before you kill yourself, or worse, someone else,simples!
