Garage Door Torsion Spring
Torsion garage door springs are most common. They use torque springs, which are tightly wound coils of metal, to generate the torque that’s needed to lift the garage door up when you open it. Because of this, they’re characterized by the turning motion you see when the garage door is raising or lowering. Torsion springs come in sets of between one and four, depending on the weight and size of the door. They require fewer parts and are more durable and less dangerous when they break than extension springs. The first way is to disengage your automatic garage door opener and raise the door manually. The door should stay in the up position with very little movement and without you needing to hold it up. The second way is to move the door to the mid-level position, halfway between fully raised and fully lowered. Again, the door should stay up on its own. If your door feels heavy, the springs may be close to breaking. If your door feels light for some reason, you may have springs that are improperly sized for your door.
Garage Door Extension Spring
Extension springs expand and contract when your garage door is lowered or raised by motor or by hand. There are generally two of them that are attached to the garage door tracks that run along the ceiling on each side of the door. It’s important to know that they can behave volatility upon breaking. This is why they’re always used along with safety cables — and why it’s extra important to know when you need extension garage door spring repair. Because extension garage door springs are relatively affordable, they’re the most common type of garage door spring for residential use. Signs of failure for extension springs are similar to those of torsion springs, but there are also some additional signs that your extension springs have already failed. First, do a visual check for any gaps in the coils. Gaps signal that the steel the springs are made from has given out, and the spring can’t produce the tension needed to move the garage door. Another thing to look out for is whether the left and right sides of your garage door don’t appear to be correctly aligned anymore. This issue usually means that one of the springs has given out and can’t lift or close that side of the door anymore.
