How to Replace a Garage Door Spring

in Spring

When it comes to garage door faults, one of the most commonly occurring is a spring breaking or damaging. In some cases, this is an easy problem to solve. However, whether or not you wish to take on the job may depend upon the type of garage door you own.

Types of Garage Door Spring

Garage doorways come with two types of spring: torsion (wound around a rod above the garage doorway) or extension springs (along the upper sides of the garage entry door). Replacing or repairing a torsion spring is not recommended as the tension in the spring is extremely high. Severe injury or death can occur from attempting a replacement, so it is advisable to seek the help of a professional. If you find that one of the torsion springs on your storage garage has broken, the other is likely to follow, so it is wise to have both springs replaced at the same time.

Extension springs, on the other hand, are not as risky and can, therefore, be replaced or repaired by your average DIY enthusiast. However, care should still be taken and safety measures followed to avoid injury.

How to Replace a Garage Door Extension Spring

1. First, lift the door until it is fully open (you may need some assistance with this). Then, place locking pliers on the track, under the lowest roller (this should be on the 'broken spring side' of the door).

2. Next, remove the broken spring or what is left of it and examine the pulleys (sheaves) to ensure that they are in proper working order. If there is significant damage to the bearings or the sides, it is wise to replace them.

3. At this point, leave the functioning spring untouched and install the new spring and cable. While installing the new spring, it is wise to only stretch it 1" with the door fully open. However, this may need adjustment later.

4. Then, release the locking pliers and place them in the corresponding location on the opposite side. Remove the unbroken spring and replace it in the same manner as before.

5. Next, remove the pliers and allow the door to close. However, ensure that no one is standing close to the springs at this point. Watch the movement of the springs and ensure that the spring sheave does not touch the fixed sheave. If it does, the spring is overstretched.

6. On the other hand, if the door is very heavy, you may need to increase the spring's stretch to 2". However, you should ensure that the sheaves are unobstructed.

7. Lastly, it is a good idea to check the safety cable. It should pass through the springs and be fastened just beyond the furthest traveling point. The safety cable is designed to restrain the spring if it breaks.

Of course, if you encounter any problems while fitting a new extension spring, it is wise to seek assistance.
