A loud bang from the garage is a homeowner’s worst nightmare. You press the opener, the motor runs, but the door won’t move. A broken garage door spring is the most common reason for this, yet most people don’t think about their springs until it’s too late and their car is trapped. When a spring snaps, it can disrupt your daily routine. While all springs eventually break down due to metal fatigue, certain factors can accelerate this process.
By understanding why garage door springs break and how to prevent them, you can spot the warning signs and schedule a preventative repair before they fail.
Understanding Torsion And Extension Spring Systems
Garage doors use a counterbalance system to lift their heavy panels. Although the opener motor initiates the movement, the springs do the actual heavy lifting.
Most residential doors use one of two types of springs:
- Torsion springs: Mounted on a shaft above the door frame, these mechanisms wind and unwind to raise and lower the door.
- Extension springs: These run along the horizontal tracks on each side, stretching and contracting to assist the door’s movement.
Some newer homes feature systems such as the Wayne Dalton TorqueMaster, which safely encloses the springs in a steel tube.
All of these springs are under extreme tension to support the door’s weight, which can be several hundred pounds. When a spring breaks, the door may not open or could slam shut, posing a serious safety hazard.
Daily Cycles Deplete Component Lifespan
Each time your garage door opens or closes, the springs complete one cycle. Manufacturers rate springs based on their expected lifespan, measured in cycles. Standard builder-grade springs are typically rated for about 10,000 cycles. While this may seem like a lot, a busy household can quickly go through them.
High-cycle springs offer a longer-lasting alternative. With lifespans of 20,000 to 50,000 cycles, these upgraded springs significantly reduce the need for frequent replacements. If your garage door is your household’s main entry point, upgrading to high-cycle springs during your next replacement can save you time, money, and hassle in the long run.
Rust Attacks Metal Strength
Moisture is a significant threat to steel springs, especially in humid or poorly ventilated garages. Rust forms on coils, weakening their structural integrity and increasing friction. In Pittsburgh winters, road salt and melting snow raise garage humidity, accelerating corrosion.
Rust stiffens the coils, increasing resistance and leading to premature snapping. To prevent rust, keep your garage dry and wipe wet floors. Inspect springs regularly; orange discoloration indicates corrosion. While deep pitting can’t be reversed, early action can slow the damage.
Cold Weather Causes Metal Fatigue
Steel contracts in cold temperatures. When the thermometer drops during a Pennsylvania winter, the metal in your garage door springs becomes more brittle. The springs must work harder to lift the door just as their molecular structure becomes less flexible. This explains why so many springs break during the first real cold snap of the year.
Aging steel is prone to thermal contraction and door shock. While the weather can’t be changed, insulating the garage keeps the temperature moderate. Insulated doors from Clopay or Garaga help retain heat and protect components from freeze-thaw cycles.
Improper Door Balance Strains Systems
A properly balanced garage door feels light when lifted manually, with springs supporting it at the halfway point. If it slams or shoots upward, adjustment is needed. Unbalanced doors strain springs, increase wear, or overload the opener. Tight springs can cause bouncing or improper closing.
To test, disconnect the opener (pull the red release cord), lift the door by hand, and ensure it moves smoothly and stays at waist height. If it drops, the springs may be faulty or have lost tension. If it flies up, they’re too tight. Always call a professional to adjust springs—DIY fixes can be dangerous.
Lubrication Reduces Harmful Friction
Friction is a major cause of wear on garage door springs. As the torsion springs wind and unwind, the coils rub against each other. Without lubrication, this metal-on-metal contact grinds away the wire, leading to premature failure.
Many people wait until they hear a squeak to lubricate, but by then, damage has already begun. We recommend applying a high-quality garage door lubricant twice a year to keep the garage door coils sliding smoothly.
Be sure to use a lithium-based grease or a silicone spray made for garage doors, not a standard WD-40, which can act as a solvent. Coat the entire spring and wipe away any drips.
Wrong Spring Size Installation
Not all springs fit all doors. Garage doors vary in weight based on size, material, and insulation thickness. A technician must calculate the precise spring size needed to counterbalance the specific door.
If an installer uses a spring designed for a lighter door, the spring will experience excessive stress when lifting the heavier panel. This over-tensioning drastically shortens the cycle life. On the other hand, a spring meant for a heavier door will make a light door difficult to close and dangerous to operate.
When replacing springs, experienced technicians measure the wire gauge, inside diameter, and length of the old spring, but they also weigh the door to verify accuracy.
Inspecting For Gaps And Separation
A visual inspection can reveal springs about to fail. Torsion springs may show signs such as gaps or separations before snapping; healthy springs have tight, uniform coils. A gap indicates the steel has yielded and lost its load-bearing capacity, risking gear damage during operation. Extension springs wear by elongation; stretched loops or uneven coils indicate the end of life.
Regular Maintenance Extends Reliability
Preventive maintenance is key to avoiding unexpected breakdowns. While some wear is inevitable, proper care delays system failure. Every six months, visually inspect cables, rollers, and springs. Listen for grinding or popping noises. Lubricate all moving parts, including hinges and rollers (except nylon rollers, which only need lubrication on the bearings).
Make sure to check the safety cables on extension springs, which run through the center of the spring and anchor to the wall or ceiling. If a spring snaps, these cables catch it, preventing damage or injury. If your extension springs don’t have safety cables, have a professional install them immediately.
Professional Inspections Keep Doors Running Safely
Garage door springs store a dangerous amount of energy, and a sudden release can cause severe injury or property damage. Spring replacement and adjustment should be performed only by professionals with the proper tools and training. Attempting this work yourself often leads to accidents. A professional technician will inspect more than just the springs; they check track alignment, test safety sensors, and examine weatherstripping.
Reliability matters. Choose a team that responds fast and comes prepared. Neglected springs fail, but proactive maintenance minimizes disruption. Keep these signs for garage door spring failure and how to prevent them, and take control of your home maintenance.
