If these are extension springs - long springs alongside a tilt-up door, then while the same strength spring should be used on each side, there is only a 10# difference (one spring size) difference between the two - 120#for green versus 130# for yellow, so I would not be too worried. Tilt-up doors also havea fair amount of slop in them, so can handle a variation in pull on the two sides without too much trouble.


If torsion springs - the ones wrapped around an axle shaft above the door opening, that lift the door with cables running down to the bottom corners, then not only are those doors more sensitive to wracking and friction from uneven pull, but the green and yellow codes are not adjacent sizes - there are several sizes between them, so it would probably be more important for them to be the same.


Here is a link to the color codes and spring sizes -

All in all, I would say if you disconnect the opener (if you know how to disconnect and reconnect it) and pull the door up and down by hand and it moves freely and does not tend to pull to one side or drag in the track on one side versus the other, then I would not be too concerned about it myself. Should also, of course, close evenly across the bottom- not haveone side lifted up when the other is closed.

Tested the door just as suggested, opens easily no unbalance. Thanks for your answer.
