An automatic garage door can be a great convenience – that is, until something gets broken. Here are some things you should know to replace broken cables on automatic garage doors.

Garage Door Cables ( Or, Actually Springs)

First, you should realize that the so-called “cables” are actually springs. There are two types: Extension springs and Torsion springs. Both types are potentially maiming, even deadly when replaced carelessly. This means that replacing them is not really a do-it-yourself project.

It is always advisable that you first consider getting a pro to replace the broken cable. The problem with this is that you have to cough up some major dough in order to avail of this. Expect to pay 150 to 300 dollars for the services of a good door man. However, you should be aware that some companies like to scam you and would charge you up to 800 dollars to replace parts that are perfectly okay. These expenses are probably the reason why you are looking for advice on how to replace broken cables on automatic garage doors in the first place.

Get Accurate Replacements

The first major tip you have to remember is to get accurate replacements. The best way to do this would be to take the broken springs to the dealer. If you have to order online, however, you should measure the overall length, the inside diameter and the wire size carefully. Remember that the springs are carefully chosen to maintain the balance of the garage door and using the wrong springs could lead to disastrous results.

Replace Both Springs

You should always replace both springs if one has already been damaged. Why? Well, when one spring is broken, you can be sure that the other one will follow soon. Replacing both springs at the same time rather than waiting for the other spring to be broken will save you time and effort.

Get New Lift Cables, Sheaves or Pulleys

Another tip on how to replace broken cables on automatic garage doors is to actually replace every other worn part in the door. You should get new lift cables, sheaves or pulleys and replace any other part which looks like it’s not going to last long. This way, you will be making the most economic use of your time and effort.

If you are replacing extension springs, you might find it easier if you put the door in the up position and then clamp it into place while you replace the springs. However, this is not the case when you are replacing torsion springs. When you are replacing torsion springs, putting the door in the up position may not give you access to the mechanism and it actually does not lessen the danger of replacement.

Always Follow The Safety Instructions

Be very vigilant during the replacement. Make sure that you get highly detailed instructions from a professional. You should know that the forces involved in replacing garage door springs can turn even a small screw into a deadly projectile. This leads us to the next tip on how to replace broken cables on automatic garage doors.

Always install a safety cable when you replace the spring. This safety cable makes sure that if the spring breaks from the tension of the door, it would not turn into a deadly missile. There have been incidents of people being killed or maimed by a spring suddenly breaking and shooting out. The safety cable should be strong enough to withstand the force of a broken spring.

These tips on how to replace broken cables on garage doors should help keep you alive during the project. However, you really should ask yourself if the money is worth the risk.
