The next most common reason garage doors come off their rails are worn or poor quality horizontal rails. When the garage door is open, the horizontal guides support almost the entire weight of the door, which, as mentioned above, can be up to 400 pounds in the case of residential garage doors. If the horizontal tracks are old or made of low-gauge steel, a small impact can cause the tracks to bend or break. The tracks should be made of 14-gauge steel and reinforced wherever possible to prevent them from bending in and out.
Misaligned rails are another common cause for a garage door to slip out of the way. This usually happens when the bolts that hold the horizontal guides loosen, causing the support to wobble at the slightest unnatural vibration of the door. With misaligned tracks, the risk of rollers slipping off the tracks increases much more. When the horizontal guides are not made of a strong material, a slight impact on the door can bend them and cause the door to fall.
That's why it's important to opt for high-quality horizontal tracks. Ideally, chains should be made of 14-gauge steel and reinforced with L-shaped angled iron to prevent buckling. It may seem silly, but the most common reason a garage door goes out of its way is because homeowners knock on their doors with their vehicles. It's important to find the cause of the problems before trying to fix the door so that it doesn't come off again.
It's important to ensure that your garage door is equipped with the correct rollers for your specific door. A single faulty roller isn't likely to cause the entire garage door to malfunction, but problems can quickly get worse, as the rollers have to work in sync. Call an experienced garage door professional to inspect the function and fix the problem before it gets out of hand. However, the impact can cause a misalignment of the guides or to bend part of the mechanism, something that the owner could overlook when repairing the doors.
If the opener cannot open the door, cables can jump out of the cable drum and cause the door to level up unevenly. Garage roads are often open to the environment and collect dust and debris when the garage is biked. In general, what happens when a car hits the garage is that some of the rollers slip off the tracks, leaving the garage door suspended solely by the elevator cables. Although rare, this problem can occur, especially on older garage doors that haven't been used for a long time.
Because of the danger inherent in repairing garage doors, all repairs must be performed by a professional. If this happens, turn off the car and leave the garage immediately, and call a local professional to get the door back in good working order. In addition, if debris accumulates on one of the roads, it can completely prevent that side from working or that the garage door from being damaged by forcing it through the obstruction. If your garage door has been changed but not your door opener, contact your local garage door professional to ensure that your garage has the proper lifting cables installed.
