Why Is My Garage Door So Heavy? 5 Signs of a Broken Torsion Spring


Have you ever tried to open your garage door manually only to find it feels like lifting a ton of bricks? Or perhaps your automatic opener is making a desperate grinding sound as it struggles to move the door just a few inches? If your once-smooth garage door suddenly feels impossibly heavy, you are likely dealing with a broken torsion spring.

A standard garage door can weigh anywhere from 150 to 500 pounds. The springs act as the "muscles" of the system, neutralizing that weight so the door can be moved with a single hand or a small electric motor. When that muscle tears, the results are immediate and frustrating. Understanding the warning signs of a failing spring can help you avoid being trapped in your garage and prevent expensive damage to your opener.

How Torsion Springs Work

Torsion springs are located on a metal rod above the door opening. As the door closes, cables attached to the bottom corners pull on the drums, tightly winding the coils. This stores energy. When you open the door, that energy is released, providing the torque necessary to lift the heavy panels.

When a spring snaps, the counter-balance system is neutralized. All that weight is now "dead weight," which is why the door feels so heavy and becomes a major safety hazard.

5 Clear Signs Your Torsion Spring is Broken

If your garage door is acting up, look for these five tell-tale symptoms to confirm a spring failure.

1. The Door Feels Incredibly Heavy

If you pull the emergency release cord (the red handle) and try to lift the door by hand, it should stay in place if you lift it halfway. If it crashes back to the floor or you can’t even budge it off the ground, your torsion spring is no longer providing support.

2. You Heard a Loud "Bang" in the Garage

Many homeowners describe the sound of a failing spring as a gunshot or a heavy metal object falling from a height. This is the sound of the steel coil snapping under hundreds of pounds of tension. If you heard a sudden, unexplained loud noise coming from the garage, check the springs above the door.

3. A Visible Gap in the Coils

Torsion springs are continuous coils of steel. When they break, they usually snap in one specific spot, creating a visible 2-to-3-inch gap between the two pieces. If you look at the metal bar above your door and see a break in the spring, it is officially broken and needs replacement.

4. The Top Section of the Door Bends

If your automatic opener tries to lift a door with a broken spring, it might pull on the top panel with so much force that it causes the metal to bend or buckle. If you see your door "crinkling" at the top when you press the button, stop immediately. Continuing to use the opener will likely burn out the motor or snap the drive belt.

5. Cables Are Loose or Dangling

When a spring loses its tension, the cables that run from the bottom of the door to the drums at the top often lose their tautness. You might see these steel cables hanging off the sides of the door or tangled around the shaft. This is a secondary sign that the primary lifting force—the spring—has failed.

The Dangers of Forcing a Heavy Door

It is tempting to try and "help" the opener by lifting the door while the motor runs, or to pull the door up manually to get your car out for work. However, this is extremely dangerous for several reasons:

  • Muscle Strain: Attempting to lift a 300-pound door without mechanical assistance can lead to severe back or shoulder injuries.

  • Opener Failure: Garage door openers are designed to move a balanced door. Forcing it to lift a heavy door can strip the gears or destroy the motor, turning a simple spring repair into a much more expensive total system replacement.

  • The Door Could Fall: Without the spring to hold it, the door can act like a guillotine. If a cable snaps or you lose your grip, the door will slam down with enough force to cause catastrophic injury or property damage.

Professional Repair vs. DIY Safety

Because torsion springs are under high tension, replacing them requires specialized tools like winding bars and a deep understanding of the torque involved. For most homeowners, calling a professional is the safest and most efficient route. A technician can typically swap out a pair of springs in about an hour, ensuring the door is perfectly balanced and the safety sensors are aligned.

Quick Summary of What to Do

  1. Stop using the opener: Unplug it to prevent accidental activation.

  2. Inspect the spring: Look for the gap in the coil above the door.

  3. Keep everyone away: Do not let children or pets near the door until it is repaired.

  4. Check both springs: If one is broken, replace both to ensure even tension and longevity.

Dealing with a heavy garage door is a major inconvenience, but it is your home's way of telling you that a critical safety component has failed. By recognizing these signs early, you can address the problem before it leads to further damage or injury.
