How To Balance A Garage Door With Extension Springs

This is accomplished by opening the garage door as fully as possible until it hits the stop bolt on the track.

How to balance a garage door with extension springs.

Retest the door balance as you did in step 1. To adjust your garage door s side mounted springs first open your door fully and secure it in place with a c clamp below the bottom roller. Weigh your garage door. From the middle of the door lift it to the halfway mark and carefully let go.

Spot the bar that runs parallel to the top of the garage door and has 2 springs on it. To be able to adjust the springs the door must be in a position that release the tension on the springs. Open it just as wide as you can without hitting the garage door opener s stop bolt and place a clamp on the track on both sides to keep the door in place. You must release the tension on the garage door springs before attempting adjustment or replacement.

With an extension spring door the goal is to take all the tension off the door before you even think about touching a spring. To keep the door from falling it must be clamped to hold it in place. For extension springs this is in the up position. Once the spring is free of tension remove from its track hanger.

You can do this by opening the door all the way and propping it up with a ladder. Place scale under the garage door on the side of the door with the broken extension spring. To perform the balance test close the garage door normally and detach the automatic opener if present. An unbalanced door can pose safety issues and tax a garage door opener.

Once your garage door is secured remove the spring hook from the track hanger which will allow you to move the hook and adjust the spring s tension. This can still be done when only one extension spring is broken. Periodic maintenance of your garage door includes balancing to ensure the door opens and closes with maximum efficiency. The bar also has a pulley at each end through which the garage door cables that open and close it pass.

Be ready to grab the door in case of dramatic movement. Raise the door and release the garage door opener. Look at the wall just above the garage door. You may need to use a 2x4 or some other object to pry the garage door open.

Adjust the springs on both sides of the door the same way. If it was opening too quickly move it to the next lower hole.
