One of the most important and dangerous components on any home garage door opener are the high tension springs which need to be regularly inspected and lubricated as per the manufacturers directions. Unfortunately, many householders are oblivious to the fact that garage door torsion springs and other parts of the door need occasional routine servicing and safety checks.
Overhead garage door opener springs are used to raise or lower the door and can present a safety risk if they are either faulty or not installed as per manufacturers instructions. If one or both of the springs are not working correctly, the door might not open all the way or even at all. Garage doors, like other mechanical and electric equipment in and around the home, need routine upkeep in order to remain in top notch condition.
The most obvious perpetrators to pay special attention to when you are experiencing trouble either opening or shutting your garage door are the high tension springs. If the springs are old, they are probably worn out to a certain point. The torsion springs used on garage doors are tightly wound and kept under extreme tension. due to this tension, even the best quality steel springs will eventually break. Garage door opener springs must be properly contained in order to stop them from causing serious harm to a person or property should there be a sudden breakage. Up and over garage doors use cables for containment while roller shutter doors use a metal tube around the spring mechanism.
Even if the springs are contained, or if the door has been fitted for a number of years, you should have them inspected by a professional garage door engineer.The springs should be replaced if needed. If you have the type of garage door that has a pair of separate springs, and just one is broken, it makes sense to replace both simultaneously. You can bet your bottom dollar that if one spring has broken, its opposite number will not be far behind it.
A definite sign that your garage door is in need of a spot of service is when the springs either start squeaking or chattering loudly when opening or lowering the door. This does not necessarily indicate that the springs are about to give up the ghost or the door is on its last legs and needs replacing. The trouble can probably be cured by spraying on some lubricant, such as WD-40, or something similar.
Another indication that your garage door needs servicing is if there are shredded and worn strips of cable hanging loose. Irrespective of the quality of your garage door opener, this is a sign that the cables are on the brink of snapping. An abrupt break in the garage door cables can cause serious injury. These chafed cables ought to be examined and more than likely replaced by a professional garage door contractor who is acquainted with the problems connected with springs and cables breaking.
Garage doors by themselves are very heavy and because of that weight, the torsion springs need to be retained under extreme tension. You should therefore not attempt any mechanical alterations yourself due to the dangers involved in doing so. It would be wise to have a professional garage door installer inspect these important parts of your home yearly to avert potential injury and problems caused by bad springs.
