What Happens When a Garage Door Cable Snaps

Have you ever heard a loud noise in your garage and then found your garage door not working properly? One possible reason could be that the garage door cable has snapped. So, what happens when a garage door cable snaps?

To put it simply, when a garage door cable breaks, it makes the door hard to open and it might get stuck. It can be dangerous, so it’s important to fix it safely or get help.

Let’s understand what this means, why it happens, and how to fix it in a simple way.

What are Garage Door Cables?

What are Garage Door Cables

Garage door cables are strong, thick wires that help lift and lower your garage door smoothly. They work together with the springs and pulleys to balance the heavy weight of the door.

So, what causes garage door cables to come off? Garage door cables come off for several reasons.

  • Wear and Tear: Cables work hard every time you open and close the door. Over time, they can get tired and break.
  • Getting hurt: If something bumps the cable or the garage door gets stuck, it can make the cable rip.
  • Rust: If the cables get rusty, they can weaken and break.
  • Poor Maintenance: If the cables aren’t taken care of, they might not last as long.
  • Heavy Use: Opening and closing the door many times a day can wear out the cables faster.
  • Too Much Weight: If the door is super heavy, the cable might not be strong enough anymore.
  • Something’s Wrong: Sometimes, other parts of the garage door, like the wheels, can get stuck and make the cable work extra hard, which could be the cause of the snap.


Signs Your Garage Door Cable Might Be About to Snap

If you can identify the problem at its early stage, which is about to happen soon, then you can take immediate action.

  • Fraying: If you see the cable starting to look like it’s coming apart, that’s a warning sign.
  • Rust: Rusty spots on the cable mean it’s getting weaker.
  • Strange Noises: If you hear squeaking or grinding when the door moves, it could be the cable.
  • Door Moves Unevenly: If one side of the door moves differently than the other, the cable might be worn out.

So, what happens when the garage door cable breaks? When the garage door cable breaks, several things can happen. 

Here are some of the most common situations:

The Door Gets Stuck

When the cable breaks, the door might get stuck in place, either open or closed. Then, you’ll face problems accessing your garage or car.

The Door Becomes Unbalanced

The cable helps keep the door balanced. When it breaks, the door can tilt to one side.

The Door Slams Shut

If the cable breaks while the door is open, the door can slam shut with a lot of force, which can damage the door or hurt someone nearby.

The Springs Get Damaged

A broken cable can damage or stretch the door’s springs, causing more problems that need fixing.

If you think your garage door cable is broken, fix it right away. Using the door with a broken cable can cause more damage you won’t even think about.

So, the garage door cable snapped. How to open?

If the door is stuck open, it’s best to leave it alone. Trying to force it can be dangerous. But if you absolutely need to get into the garage, here’s what grown-ups can do (important! never try this yourself!):

  • Call a superhero, also known as a garage door repair person.
  • If they can’t come right away, grown-ups can carefully cut the other cable (with the right tools!) to lower the door slowly. But remember, this can be tricky and dangerous, so it’s always best to wait for a grown-up helper.

NOTE: Be very careful when trying to fix this, and have a few people help you lower the door slowly and safely after cutting the cable.
