Your garage door is an essential part of your home, providing security, convenience, and protection for your vehicles and belongings.

Like any other mechanical system, garage doors can experience issues over time. One of the most common and potentially dangerous problems is a snapped garage door cable.

In this article I will tell you what garage door cables are, how to recognize the signs of broken cables, the dangers they cause, and what you can do to solve the problem. We’ll also go over preventative measures and discuss when it’s time to call a professional.

What is a Garage Door Cable?

To understand what to do when a garage door cable snaps, it’s crucial to first grasp what a garage door cable is. Garage door cables are sturdy, steel components that play a vital role in the operation of your garage door.

They are typically made from braided steel wires and are responsible for lifting and lowering the door. These cables are attached to the bottom bracket on the bottom panel of the garage door and then run along the door’s sides and up to the drum at the top.

What are the Signs that a Garage Door Cable has Snapped?

Recognizing a snapped garage door cable is important for your safety and the security of your property. Here are some telltale signs that your garage door cable has snapped:

1. Asymmetrical Movement: When one side of the door appears lower than the other or the door is crooked, it’s a clear sign of a cable issue.
2. Unusual Noises: If you hear grinding or snapping sounds when operating your garage door, it may indicate cable damage.
3. Cable Hangs Loose: Inspect the cables visually. If you notice any loose, frayed, or hanging cables, it’s a clear indication of a problem.
4. Stuck Door: A garage door that refuses to open or close may be due to a snapped cable.

What are the Dangers of a Snapped Garage Door Cable?

A snapped garage door cable can pose significant dangers, both to you and your property. It’s essential to be aware of these risks:

1. Injury: Attempting to operate a garage door with a snapped cable can lead to serious injuries. The door may fall suddenly and unexpectedly.
2. Property Damage: A falling garage door can cause extensive damage to your vehicle, belongings, and the door itself.
3. Security Risk: A malfunctioning garage door compromises the security of your home, making it easier for intruders to access your property.

How to Safely Lower a Garage Door with a Snapped Cable

If you suspect that your garage door cable has snapped, it’s essential to know how to safely lower the door to prevent accidents. Follow these steps:

1. Disengage the Door: Locate the emergency release cord (usually a red rope) and gently pull it to disengage the door from the opener.
2. Manually Lower the Door: Carefully grip the door on both sides and lower it to the ground slowly. Ensure there are no obstructions in its path.
3. Secure the Door: Once the door is fully closed, secure it in the down position to prevent it from accidentally opening.
