How To Replace Spring Cable On Garage Door

Garage door springs are an essential part of the door's operation, as they provide the tension needed to lift and lower the door. Over time, these springs can wear out or break, which can prevent the door from opening or closing properly. If you find yourself in this situation, you will need to replace the spring cable. Here are the steps on how to do it:

1. Safety First

Before you begin, it is important to take some safety precautions. First, make sure that the garage door is disconnected from the opener. You can do this by pulling the release cord or by flipping the switch on the opener motor. Next, place a pair of safety blocks under the door to prevent it from falling if the spring breaks.

2. Remove the Old Spring Cable

Once the door is secure, you can begin removing the old spring cable. Start by locating the two bolts that hold the spring cable to the door frame. These bolts are typically located on the top and bottom of the door frame. Once you have located the bolts, use a wrench to loosen them. Be careful not to remove the bolts completely, as the spring is still under tension.

Once the bolts are loose, you can carefully remove the spring cable from the door frame. Be sure to support the spring with one hand as you remove it, as it will be under tension.

3. Install the New Spring Cable

With the old spring cable removed, you can now install the new one. Start by feeding the new cable through the hole in the door frame. Once the cable is through the hole, attach it to the top bolt on the door frame. Tighten the bolt until it is snug, but do not overtighten it.

Next, attach the other end of the spring cable to the bottom bolt on the door frame. Again, tighten the bolt until it is snug, but do not overtighten it.

4. Adjust the Tension

Once the new spring cable is installed, you will need to adjust the tension. To do this, use a pair of pliers to turn the adjustment nut on the spring. Turn the nut clockwise to increase the tension and counterclockwise to decrease the tension.

The correct tension for the spring will depend on the weight of the door. If the tension is too low, the door will be difficult to open and close. If the tension is too high, the springs could break.

To test the tension, open and close the door several times. If the door opens and closes smoothly, then the tension is correct. If the door is difficult to open or close, then you will need to adjust the tension.

5. Reconnect the Garage Door Opener

Once the spring cable is installed and adjusted, you can reconnect the garage door opener. To do this, simply plug the opener back into the outlet and then press the button on the opener to open the door.

6. Test the Door

Once the opener is reconnected, test the door to make sure that it is working properly. Open and close the door several times to make sure that it opens and closes smoothly. If the door is not working properly, then you may need to adjust the tension on the spring cable.

Replacing a spring cable on a garage door is a relatively simple task that can be completed in a few hours. By following these steps, you can save yourself the cost of hiring a professional.
