Garage Door Spring Cycle Life

If you only go in and out of your garage once a day that means you should expect a broken garage door spring around 14 years after the spring is first installed.

Garage door spring cycle life.

Obviously the more the door is used the sooner the springs will break down. The average garage door spring if correctly installed should last about 10 000 cycles of opening and closing. The required number of cycles is calculated by determining the average number of operating cycles per day multiplying this figure by 250 days and then multiplying the result by 10 years the useful life of a garage door. In residential garage door springs life cycles are usually 10 000 20 000 or 30 000 cycles.

The choice of the torsion spring is made according to the number of cycles thus obtained. This means your spring should hold up for approximately 10 000 turns of the coil which equates to the garage door going up once and down once. Many times we find that the wrong size. The standard cycle life for a torsion spring on a garage door is 10 000 cycles.

As long as the only difference between the springs is the length the formula for matching cycle life is simple. The least expensive springs available rated at 10 000 life cycles or less. On average a 10 000 cycle rating can only give you a few years of service. A cycle represents opening and closing the door one time.

If you go in and out twice a day you re down to 7 years. This is dependent on the builder installing the proper size spring s.
