What Does a Garage Door Cable Do?
Garage door cables are critical safety components. They work together with the springs to lift and lower the door smoothly and evenly.
Key Functions of Garage Door Cables
- Support the weight of the door
- Keep the door balanced
- Prevent the door from falling suddenly
- Transfer spring tension to lifting motion
According to industry data, a standard double garage door can weigh 200–350 pounds, making intact cables essential for safe operation.
For a technical overview of garage door components, you can refer to the garage door explanation on Wikipedia:

Is It Safe to Open a Garage Door When the Cable Is Broken?
Short answer: usually no—but sometimes yes, with strict precautions.
A broken cable creates an imbalanced door, which can:
- Drop suddenly
- Twist off the tracks
- Cause severe injury
- Damage rollers, tracks, or panels
Professional garage door technicians report that over 30% of garage door injuries occur during DIY attempts involving broken cables or springs.
How To Tell If Your Garage Door Cable Is Broken
Before attempting anything, confirm the problem.
Common Signs of a Broken Cable
- Door opens crooked or uneven
- One side rises while the other stays down
- Door slams shut suddenly
- Visible frayed or hanging cable
- Loud snapping or banging sound earlier
If you notice any of these signs, stop using the automatic opener immediately.
How To Open Garage Door When Cable Is Broken (Emergency Only)
⚠️ Important: These steps are for emergency access only. This is not a repair.
Step 1: Disconnect the Garage Door Opener
- Ensure the door is fully closed
- Pull the red emergency release cord straight down
- This disengages the opener from the door
This prevents motor damage and uncontrolled movement.
Step 2: Inspect Door Balance Visually
Before lifting:
- Check if both cables are broken or only one
- If one cable is broken, the door will be heavily tilted
- If both cables are broken, the door may be extremely heavy
❌ If the door looks severely crooked—do not proceed.
Step 3: Use At Least Two Adults to Lift
If you must open the door:
- Use two or more adults
- Wear work gloves
- Stand on opposite sides of the door
- Lift slowly and evenly
Never stand directly underneath the door.
Step 4: Lift Only Partially (If Needed)
If you only need to remove a vehicle:
- Lift the door just high enough (3–4 feet)
- Do not raise it fully
- Avoid sudden movements
Step 5: Secure the Door Immediately
Once lifted:
- Use locking pliers or C-clamps
- Clamp them onto both tracks below the rollers
- This prevents the door from slipping down
Never rely on strength alone to hold the door open.
When You Should NOT Attempt to Open the Door
Do not try to open the garage door if:
- The door weighs more than you can control
- The door is off-track
- You hear grinding or popping sounds
- You are alone
- The cable broke along with a spring
In these cases, waiting for a professional is the safest option.
Why Garage Door Cables Break
Understanding the cause helps prevent future failures.
Most Common Causes
- Normal wear and tear (10–15 years lifespan)
- Rust or corrosion
- Poor maintenance
- Misaligned tracks
- Broken springs increasing cable tension
Garage doors used 4–6 times daily experience faster cable wear.
