If that point is more than four feet or less than three feet above the ground you will need to balance the door.
Proper garage door balance.
A door that starts sliding down slams closed on its own or that opens further on its own needs its springs adjusted.
The springs extend along the shaft and work by twisting as the garage door closes by means of cables attached to each side of the lowest garage door panel.
If the door continues to rise the spring tension is too strong.
This tension makes it easier to lift the garage door from its closed position.
A balanced garage door will keep your automatic opener happy by working with the weight limits it was designed for.
Checking the garage door balance before you can adjust your garage door you have to know in which direction it s out of balance.
Hopefully you will find yourself next to goldilocks with a well balanced garage door that is just right.
Balance the garage door if it lowers or raises on its own.
A balanced garage door is an important part of your garage.
Garage door springs offset the weight of the door and allow it to open and close with ease.
To do this you ll have to disconnect your garage door from your opener and check how well the door hangs on its own.
When a garage door is properly balanced the springs completely support the door and the door remains in place with minimal upward or downward movement.
If the door falls to the lower position quickly the spring tension is too weak.
A problem with the spring tension could cause the door to open or close unevenly improperly or at the wrong speed and adjusting the springs will likely solve the problem.
In a sectional torsion spring system this is done using one or more torsion springs that are attached to a torsion tube at the top of the garage door opening.
Side mounted springs are long heavy springs mounted on each side of the upper garage door track.
Move the garage door up and down until you find a place where the door stays suspended when you let go.
A garage door uses a spring system to counter balance the weight of the garage door.
