# Cables & Drums - FAQs & Troubleshooting

Garage door cables and drums work together with the spring system to lift and balance the garage door safely. Different spring systems use different cable types, drum assemblies, and mounting configurations.

## Garage Door Cable Types

The correct cable depends on the type of spring system installed on the garage door.

-   **Torsion Spring Systems:** use lift cables that wrap around grooved cable drums mounted at the ends of the torsion shaft.

## Garage Door Safety Cables

Safety cables are required on extension spring garage door systems. These cables run through the center of the extension springs to help contain the spring if it breaks under tension.

Missing or damaged safety cables can create a dangerous condition if an extension spring fails.

## Why Garage Door Cables Come Off the Drum

Garage door lift cables may come off the cable drums when spring tension is lost or when the garage door becomes uneven during operation.

Common causes include:

-   Broken garage door springs
-   Door obstruction during operation
-   Loose or uneven cable tension
-   Improper drum alignment
-   Garage door impact damage

Once the cable loses tension, it can unwind from the drum grooves and jam the door.

## Garage Door Cable Drums

Cable drums mount at the ends of the torsion shaft and guide the lift cables as the door opens and closes. Drum size and cable wrap configuration must match the garage door height and spring setup.

Proper cable alignment is important to keep the cables seated evenly in the drum grooves.

## Frayed or Broken Garage Door Cables

Frayed or damaged garage door cables should be replaced immediately. Lift cables cannot be safely repaired once damaged.

Common signs of cable wear include:

-   Visible fraying or broken strands
-   Door hanging unevenly
-   Cables slipping off drums
-   Door jamming during operation

Lift cables should generally be replaced in pairs to maintain proper door balance.

## Garage Door Hanging Crooked

A crooked or uneven garage door is commonly caused by a broken cable, slipped drum cable, or uneven spring tension between the left and right sides of the door.

Continuing to operate the door in this condition can damage tracks, rollers, hinges, and opener components.

## TorqueMaster Cable Drum Kits

Wayne Dalton TorqueMaster cables are not sold separately from the drum assembly. Replacement cables come preinstalled on the replacement drum kit.
