The torsion spring on the garage door tightens when the door is closed and unrolls when opened. This winding and unwinding of the torsion spring helps to open and close the garage. When the spring releases its tension when you open the door, the energy stored in the spring assists in lifting the weight of the door. Torsion springs are usually mounted horizontally above the garage door opening. When the door is pulled down, the cables connected to the lower corners force the springs to roll up, which in turn energizes the system.
When you open the door, the springs unroll and their energy is transferred to the door, helping it to lift and making it easier to open. The most common type of garage door system is a torsion spring system. Torsion springs are usually mounted horizontally above the door opening. When the door is lowered, the cables that are connected to the lower corners of the door cause the springs to wind and this winding creates stored energy. When the door is opened, the springs unroll and their energy helps lift the garage door.
However, as it goes up and down in cycles, the steel in the springs weakens and can no longer lift it. If you open it, be sure not to pull on the release cord, as these heavy doors can collapse and damage your garage door system. Your garage door is an essential part of your home and you can rely on it every day to do a simple task. If you need help selecting the right torsion spring for your garage door, let Garage Door Nation's virtual Spring Wizard guide you through the process step by step. For garage doors with a single torsion spring, if it is wound to the right, it will be placed on the left side of the J-bar.
However, this system does not last forever and, as it moves up and down many times, its steel weakens and eventually breaks. If you have any questions about how your garage door works or think it might work better, contact Precision Garage Door for a complete garage door review. For garage doors with a torsion spring, it is placed off-center on one side of the arm (also called a J-bar, since it is shaped like a letter J). Garage doors with two torsion springs will have them centered, placed together and in contact, with each one extending beyond each side of the J-bar. To calculate its life cycle, divide its life cycle by how many times you open and close your garage door each day. When you close your garage door, its springs stretch and when you open it, their energy stored in their extended state helps lift it.
For garage doors with two garage door torsion springs, one is located to the left of the J-bar (or center support), facing towards your garage's rear. As stated above, unless you have years of experience and all of the right tools, it's essential that you call a specialist to repair your garage door. To check if your springs are broken, pull on its emergency release cord with your garage door closed. As mentioned above, most garage doors come with multiple torsion springs so if one breaks, it's best to replace all of them at once since its partner is also at its end of its useful life.
