It’s an unsettling feeling when your garage door suddenly stops working—and even more so when you discover the garage door cable broke on one side. This issue not only disrupts your routine but can also pose serious safety risks if not repaired and handled promptly and professionally.

This article explores what you need to know, what to do, and how to handle it safely and efficiently.

Garage Door Cable Broke on One Side? Here’s What to Do Next

If your garage door cable broke on one side, your door may appear crooked or become completely unresponsive. Many homeowners panic, unsure whether to try fixing it themselves or wait for a technician.

Unfortunately, attempting to operate the door in this state can cause more damage. These cables are under high tension and are critical to the door’s balance and function. Continuing to use a damaged system can result in injury or property damage.

Here’s how to navigate this situation with care and expertise.

Why Garage Door Cables Matter

Garage door cables are an essential part of your garage door’s counterbalance system. They work in conjunction with the torsion or extension springs to lift and lower the door smoothly and evenly. When functioning properly, they reduce strain on the motor and ensure the door operates safely.

If a garage door cable broke on one side, the entire system becomes unstable. That’s why cables must be maintained and replaced before they wear out completely. Their role is not just mechanical—it’s critical to your safety.

Regular inspections help detect early signs of fraying or tension loss.

Signs Your Garage Door Cable Has Snapped

Recognizing the warning signs can prevent further damage and keep you safe. If the garage door cable broke on one side, you may notice the door is uneven, tilted, or stuck halfway open.

Sometimes the door may not move at all, or it may make loud scraping noises as it attempts to function. You might see a loose cable hanging from one side of the track. Another sign is the door opening crookedly or closing faster than usual.

These symptoms indicate it’s time to call a professional before attempting to use the door again.

Immediate Safety Precautions to Take

When a garage door cable broke on one side, the first and most important step is to stop using the door immediately. Disconnect the opener to prevent accidental operation. Keep pets and children away from the area, and avoid standing directly under the door.

Do not attempt to manually lift or close the door. The remaining cable and spring are likely under increased stress and could snap or cause the door to fall suddenly. Contact a trained technician right away.

Securing the area and avoiding interaction with the system will prevent injuries and additional damage.

Common Causes of Cable Failure

There are several reasons why a garage door cable broke on one side.

The most common is wear and tear over time—cables endure constant tension and friction. Rust and corrosion also weaken the steel over time, especially in humid or coastal environments. Poor installation or low-quality parts may shorten the lifespan of the cable. In some cases, improper door alignment or spring tension can cause one cable to carry more weight, accelerating its failure.

Regular maintenance and prompt repairs can help identify these issues before a cable snaps unexpectedly.

The Risks of Operating a Garage Door with a Broken Cable

Continuing to use your garage door after a garage door cable broke on one side is extremely risky. The door may fall suddenly, causing injury or damaging your car, floor, or belongings. The added strain on the remaining components can lead to additional failures, including broken springs or motor burnout.

A misaligned or jammed door can also trap vehicles inside or leave your home exposed. Ignoring the issue doesn’t just compromise safety—it leads to more expensive repairs down the line. It’s crucial to have the door inspected and fixed as soon as the problem is identified.

Why You Should Avoid DIY Repairs

When a garage door cable broke on one side, you might be tempted to fix it yourself—but resist the urge.

Garage door systems are complex and under high tension. Without proper training and tools, trying to replace or adjust cables can result in serious injuries. You may also accidentally void warranties or cause damage that leads to higher costs.

Professional technicians follow safety protocols and use specialized equipment to ensure the job is done correctly. Hiring a pro saves time, reduces risk, and ensures your door works safely and smoothly again.

How a Professional Technician Handles the Issue

When a garage door cable breaks on one side, a professional technician will begin by inspecting the entire system.

They’ll assess both cables, springs, pulleys, and door alignment to determine the full extent of the damage. The technician will then release tension from the springs before removing and replacing the damaged cable. Often, both cables are replaced at once to maintain balance. 

Once reassembled, the door is tested multiple times for smooth operation. A thorough safety inspection ensures everything is functioning properly before the job is considered complete.

Preventative Maintenance Tips from Experts

To avoid future issues where a garage door cable broke on one side, schedule annual inspections by a licensed technician. They’ll spot signs of fraying, corrosion, or uneven tension before failure occurs.

Keep the cables and springs clean and lubricated with a silicone-based spray. Avoid using the door excessively if you hear grinding or popping noises. Make sure the door stays balanced and opens smoothly—any resistance could be a warning sign.

Routine maintenance saves money and extends the life of your door system. An ounce of prevention is worth a pound of repair.

Choosing the Right Garage Door Repair Service

When a garage door cable broke on one side, choosing the right repair service is essential. Look for licensed, insured, and well-reviewed professionals in your area. A reputable technician will provide a detailed estimate and transparent pricing.

Ask if they use high-quality parts and offer warranties on labor. Choose a service with emergency availability if you need urgent repairs. Local companies often offer faster response times and better customer service.

Don’t trust your safety to unqualified handymen—your garage door deserves professional attention.
