This might be coming from a company, and truth be told fixing garage doors is what we do for a living, but it's highly important to us to tell you that this is a matter of safety. Ask any professional in the business, and the answer will be no. Unless you’re a fully qualified technician with years of experience, we would not suggest that you try to handle such a dangerous device by yourself. Garage door springs of either torsion or extension type can be extremely dangerous when they break, as they can whip around and cause severe lacerations. The reason for this is the way they support the door is by storing force and tension in their coils. Naturally, they wear over time and at some point they will snap. There are signs, such as the door seeming slightly out of balance, the springs looking odd or rusty, and more. Remember, it's important not to handle, touch or adjust the springs on your own, let alone replace them. There's also a matter of buying the best type and size of springs to support your door. Even if it's a standard size, wooden doors weight a lot more than aluminum ones, and thus need stronger and more durable torsion springs.
