Garage Door Drum and Cable Winding Problems: Why One Side of the Door Rises First

When a garage door begins lifting unevenly, homeowners often look first at the track. The track may be involved, but the problem can also begin higher in the lifting system where cables wrap around drums near the torsion shaft. If one cable is winding differently from the other, the door can tilt, jam, or place unusual pressure on rollers and tracks.

For Park Ridge and other Illinois homeowners, uneven lifting should be treated as a system warning rather than something to correct by pulling on the lower side of the door. AAA Garage Door Repair provides spring, cable, roller, section, and general garage door repair service across Illinois.

What the Cable Drums Do

On many torsion-spring systems, lift cables run from the lower part of the door up to drums mounted near the top. As the door opens and closes, the cables wind and unwind in a controlled pattern so both sides of the door move together.

If a cable slips, frays, loses tension, or winds incorrectly, one side may travel differently from the other. The door can still move for a short time, but the remaining hardware is being asked to compensate for an uneven load.

Warning Signs of a Drum or Cable Winding Problem

Look for repeated movement changes and visible cable irregularities.

• One side of the door rises before the other.
• A cable looks loose while the other side appears tight.
• Cable strands are frayed, rusted, or no longer sitting cleanly on the drum.
• The door becomes crooked partway through travel.
• A scraping or snapping sound comes from the upper corner area.
• The opener runs but the door jams after moving a short distance.
•  A cable appears to have jumped out of its normal groove.

If the door is visibly tilted or a cable is off the drum, stop operating it.

Why Repeated Opener Use Can Make the Damage Worse

The opener can pull on the center of the door even when the two sides are no longer lifting evenly. That force can twist sections, push rollers against the tracks, and increase stress on the remaining cable.

A problem that begins with cable winding can therefore spread into track, roller, hinge, or panel damage if the door is cycled repeatedly. With this, you will need to handle a garage door drum and cable issue the right way. 

Tips for Effective Garage Door Drum and Cable Maintenance

Worn cables, damaged drums, or improper tension can cause noisy operation, uneven movement, or even sudden door failure. Regular inspections and timely maintenance can help prevent costly repairs and extend the life of your garage door components. Below, we’ll cover practical tips and best practices for keeping your drums and cables in good working condition 

Do Not Try to Rewind the Cable Yourself

Cables and drums work with the spring system, and the hardware may be under substantial tension. Loosening set screws, turning drums, or reattaching cables without the correct procedure can cause sudden movement.

DASMA’s garage door safety tips specifically warn about worn cables and high-tension spring components and recommend trained service for these repairs.

Avoid Operating the Door

Do not operate a door that is hanging at an angle, has a loose cable, has a roller leaving the track, or appears partly unsupported. Keep people, vehicles, and pets away from the opening until the door can be inspected.

Check for Garage Door Spring Issues

A spring problem can affect how much lifting force is available, and a door with multiple springs may behave differently when one fails. Track damage or a seized roller can also make one side lag behind.

Enlist a Garage Door Specialist for the Job

A technician should inspect the spring system, both cables, drums, tracks, rollers, brackets, and door balance rather than assuming the drum is the only issue.

After the source is corrected, both cables should wind properly, the door should travel level, rollers should remain correctly seated, and the opener should move the door without unusual strain. The technician should also check whether the uneven lifting caused secondary damage before returning the system to service.

AAA’s garage door services page lists spring replacement, rollers, cables, section replacement, maintenance, and emergency service among the company’s repair capabilities.

Final Takeaway

Cable drums are easy to overlook because they are mounted above eye level, but they play an important role in keeping both sides of the door moving together. Uneven lifting, loose cables, poor winding, and a crooked door are signs that the system needs prompt attention.

If one side of your garage door rises first or a cable looks loose or damaged, contact AAA Garage Door Repair for professional service in Park Ridge and other Illinois service areas.
