If your garage door is broken and simply will not open up, the chances are that either your garage door spring or cable has broken. It is likely that you may even be experiencing a combination of the two.
Your garage door mechanism is made up of two cables, the support cable and the working cable, and the spring. The safety cable is a cable which runs through the centre of your spring to catch it if your working cable should break. The safety cable is in place because the spring is very heavy and can harm nearby persons or things if not supported when released.
All you will need to replace your garage door spring and cable is your toolbox, a pair of gloves, some clamps, two replacement cables and a new spring. Ensure that the garage is well-lighted and that you have all the necessary tools nearby.
When starting your garage door repair, the first thing that you will need to do is to switch your garage door onto manual mode. This is done by pulling the dangling lever just ahead of the shuttle. Now that your door is on manual, you will be able to open the door.
Once the door is fully open, secure a C-clamp on the track of both sides. Make sure that you have made it as tight as possible! The purpose of the C-clamp is to stop the garage door from sliding down while you are working on it so you must ensure that the clamp is placed right underneath the door.
Now, you are going to tackle the garage door cable repair. Put on your safety gloves and remove the broken cable, safety cable and spring. Sometimes when the cable snaps, it can become rather tangled. Take care not to cut yourself on the wire.
Thread your new safety cable through your new spring and secure the first end exactly where the old one was, which should be a screw-eye on the support frame. On the spring, you will see a pulley. Thread your new working cable over the pulley and then secure it to the bottom of the garage door. Make sure your cable has good tension, you may need to adjust the length of your cable. Secure the other end of your safety cable to the bottom of the garage door as well.
Once you have done all that, you will need to switch your shuttle back into automatic, remove your clamps and test your garage door. Do not worry if you weren’t able to get it to open. This can be a difficult process and you are encouraged to contact a professional if you do not have the required skills or tools to take on the responsibility of repairing the garage door.
To ensure that this situation does not catch you off of your guard ever again, bear in mind that garage door spring repair or replacement should be assessed after around 10 000 cycles (opening and closing). Try to determine how many times a day you or your family will use the garage door so that you will be able to maintain good function and not have to resort to a full garage door replacement.
