Your garage door opener: You obviously have one to which you are adding this system. Do your homework and make sure it’s compatible before you buy. If you’re not positive, call or email them with your make and model numbers in hand. Mine is a Craftsman (Chamberlain) made in 1999 with the door sensors so I was good to go. NOTE: Garage door openers have a limit to the number of remotes they can support. My Craftsman supports 4 remotes. With two HomeLink-connected cars, the remote door opener, and the smart hub I am now at the max allowed by my opener. As a result, I had to decommission my "clickers". Do your homework and factor this into your plans.


The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring. 

My opener also has 2 wheels on the top of each side of the door: one with a big spool of line and the other just a pulley wheel. So I also lubricated the axles of those spools. You can watch closely while raising/lowering the door to see where the parts spin and move. Now my door runs much quieter, so I must have done something right! Hopefully this will reduce strain on the motor and make it last longer.

“Every spring on every garage door will break,” says Jim Rice, owner of Broad Ripple Overhead Doors & Openers in Indianapolis. “After so many thousand times up and down, it gets metal fatigue and snaps. At least once a year, you should disconnect the garage door springs and lift the door up manually to see how well it’s balanced. Unless you hear metal screeching or something breaks, you don’t need us.”


The following instructions can be followed by most do-it-yourselfers. You will need a second person to help you at the beginning of this tutorial to raise the door so that you can replace your torsion springs. These instructions are for replacing two springs on a self-storage roll-up door, also known as a mini-warehouse curtain door, that have the typical self-storage style loops on each end of the springs.

With hundreds of moving parts that are all required to work together, it's no surprise that garage doors may need occasional repair and maintenance. Garage door repair services are also required in emergency situations, like when the garage door won't operate and the car is trapped inside or you've accidentally backed into the door when it was closed. Whether it's a specific repair of your garage door opener, a broken spring that needs to be replaced, or a bent or rusted track, The Home Depot's local, licensed service providers can get the job done quickly and efficiently.
