How Garage Door Springs Break03/30/2017 Back To Blog
Springs are some of the most important functional parts of your entire garage setup. These coils are made to be strong and durable because they're intended to carry the full weight of the installed garage door that could sometimes weigh upwards of 300 pounds. There are two types of springs that are used in the garage: the torsion and extension springs. Many of the mechanisms of how garage door springs break are similar, so they'll be talked about together.
The Cycle Life Concern
The cycle life of a standard spring may be somewhere between 5,000 and 30,000 cycles. A cycle is equivalent to one opening and closing of the door. There are no set guidelines regarding the number of cycles springs are supposed to endure so each manufacturer has their own standard. At the low end, a spring with a cycle life of 5,000 that goes into two cycles per day, will last about 7 years. At the opposite extreme, a 30,000 cycle life spring will last about 41 years. Keep in mind however that these estimates are all under ideal conditions and they do not accurately predict when you'll have to deal with a broken garage door spring.
The Problem with Rust
It's typical for springs to get a little bit rusty in the course of a few years. When this happens, the integrity of the coil will be compromised and this will significantly reduce its cycle life, leading to an earlier need for a broken spring replacement. Another way rust interferes with the action of the spring is with friction. Rusted coils that rub against each other produce more friction because of more resistance. This resistance puts more stress on the coil resulting in relatively more wear and tear and more reasons for a professional garage door adjustment.
The Effect of More Stress
When doors stick because of a bent or dirty track or a rusty roller, it's going to put more stress on the spring. This results in the spring being subjected to more stress than is necessary, which reduces the number of cycles it can endure. This same problem is present when the door's weight is more than what is indicated on the spring's specifications.
