All I might add to what DT said and the link he gave you is to make sure
you get the proper strength springs to match your door's weight.
Sometimes the springs are color coded with paint, to assist getting the
correct replacements, but the most certain test is to carefully lower
the door onto a bathroom scale with the door's springs disconnected.
(This may take a couple of husky guys to help you with.)
If the weight of the door exceeds the scale's range, you can easily
double that range with a simple lever made out of a foot or two length
of 2 by 4 and a brick. Put one end of wood on the scale and the other on
the brick and place that rig so the door gets lowered onto the center of
the piece of wood, then just double the scale's reading.
Once you know the weight of the door, just buy springs with a rating
close to that weight.
HTH,
Jeff
