NEVER adjust, remove, or install springs on your own. ALWAYS call a professional to do the work for you. As this can be a very dangerous procedure because of the tension of the spring kicking back at you.
It is extremely important to ALWAYS replace both springs as a set! This rule is full of common sense, and should be followed for safety reasons and financially! If one spring has broken, the other is not far behind. The strength of a spring decreases with time and use. The new spring used with an old spring can cause imbalance in the door that won't be able to be corrected through adjustment.
