How to Fix a Garage Door Cable in Tempe

By the Tempe Garage Door Service team · Updated October 2026

What to do first

1. Stop using the door and unplug the opener so nobody presses the button by accident.
2. Keep people, pets and cars away from the door opening, especially if the door is crooked or partly open.
3. Do not pull the red emergency release cord on a crooked door, because the door can fall when the opener lets go.
4. Take photos of the cable, the drum at the top corner and the bottom bracket from a safe distance.
5. Call to be connected with a local provider and describe what you see.

What does a garage door cable do, and how can you tell it broke?

A garage door cable connects the bottom corners of the door to the drums above it, and it works with the springs to lift and lower the door evenly. In Tempe, most homes have two lift cables, one on each side. When one fails, the door usually shows it right away.

Common signs of a cable problem include:

• The door hangs lower on one side or sits crooked in the opening.
• A cable is hanging loose, coiled on the floor or wrapped off its drum.
• You see frayed strands or rust near the bottom bracket.
• The door jerks, shudders or slams down instead of moving smoothly.
• The opener strains or stops partway.

Can I learn how to fix garage door cable problems myself?

You can learn how to fix garage door cable problems in the sense of knowing what went wrong, but the repair itself is not a safe do-it-yourself job for most Tempe homeowners. Replacing or rethreading a cable almost always means releasing and then resetting spring tension.

Torsion springs above the door are wound tight enough to lift a heavy door. Extension springs on the sides stretch under load. If a tool slips or a part gives way during the repair, the spring energy has to go somewhere, and that can mean a spinning bar, a whipping cable or a falling door.

Online videos make it look simple because they skip the near misses. Safe steps you can take are the ones in the list above: stop, secure, document and call. Not sure which springs you have? Our guide to torsion vs. extension springs explains the difference.

Why is a snapped or loose garage door cable dangerous?

A snapped or loose garage door cable is dangerous because the door is no longer balanced, and the remaining cable and spring may be carrying the full load. The door can drop suddenly, twist in its tracks or come down faster than the opener expects.

Here is what can go wrong if you keep using it:

• The second cable can snap under the extra load.
• Rollers can jump out of the track and leave the door hanging.
• Panels can bend or crack when one side lifts and the other does not.
• The opener can burn out its gear trying to lift an unbalanced door.

A door that drops is heavy enough to hurt someone or damage a car, so keep the area clear until a provider has checked it.

What causes garage door cables to fray, slip or snap?

Garage door cables usually fail from wear over time, rust, a worn drum or bottom bracket, or a door that was out of balance for a long while. Most cable problems build up slowly before the day the cable finally gives out.

• Normal wear. Every open and close bends the cable around the drum.
• Rust and grit. Dust and moisture wear the strands where the cable meets the bottom bracket.
• Spring problems. A weak or broken spring shifts more load onto the cables.
• Off-track rollers. A door that binds in the track can pull a cable off its drum.
• Impact. Backing into the door can bend the track and loosen a cable.

Once a provider finds the cause, the fix can address it so the new cable does not fail the same way.

Is it a cable problem, a spring problem or an off-track door?

A cable problem, a broken spring and an off-track door can look alike, because all three make the door crooked, noisy or stuck. A provider can tell them apart during an inspection, but a few clues help you describe the problem on the phone.

• Cable: a loose or tangled cable near a bottom corner or a top drum.
• Torsion spring: a visible gap in the coil above the door, often after a loud bang.
• Off track: rollers sitting outside the track or a door tilted in the opening.

Often more than one is involved. A broken spring can leave a cable slack, and a slack cable can pull the door off track. Learn more on our garage door spring repair and off-track repair pages.

What happens during a garage door cable repair visit?

During a garage door cable repair visit in Tempe, the provider inspects the door, explains what failed and why, and gives you a written quote before any work starts. You decide whether to go ahead.

• Inspection. The provider checks both cables, the drums, bottom brackets, springs, rollers, tracks and the opener.
• Explanation. You hear what failed and what else looks worn.
• Options. You may hear about replacing one cable, both cables, or related parts like drums or springs.
• Written quote. You get the price in writing before the repair begins.

Ask questions until you understand the options. A good visit ends with the door balanced and tested.

Should both garage door cables be replaced at the same time?

Many providers suggest replacing both garage door cables at the same time, because the two cables have done the same work for the same number of years. If one is frayed or snapped, the other has likely worn too.

Replacing both also helps the door stay balanced, since new and old cables can stretch differently. The provider may also check whether the drums, bottom brackets and springs are worn. Ask them to show you the wear on the old parts so you can make the call with the facts in front of you.

How can you keep garage door cables from failing again?

You can help keep garage door cables from failing again by looking at them a few times a year, keeping the door balanced and getting regular maintenance. Simple checks from a safe distance catch most problems early.

• Look for fraying, rust or kinks near the bottom brackets.
• Watch the door move. It should rise and fall evenly on both sides.
• Listen for new grinding, snapping or squealing sounds.
• Keep the tracks clear of dust and debris after storms.
• Never adjust the cables or springs yourself.

A yearly maintenance and tune-up visit lets a provider check cable wear, spring balance and the opener together.

What should Tempe homeowners know about heat, storms and Arizona contractor rules?

Homeowners in Tempe, Mesa, Chandler and Ahwatukee share the same desert weather and the same Arizona contractor rules. Keep these facts in mind when a cable fails.

• Long hot seasons. Phoenix Sky Harbor averages 111 days a year at 100°F or hotter (1991-2020 normals), so a stuck garage can turn into a hot, uncomfortable problem fast. Stay safe in the heat while you wait for help.
• Monsoon season. The National Weather Service defines the Southwest monsoon as June 15 through September 30, and says dust storms can bring wind gusts of 40 to 60 mph. After a storm, look for debris in the tracks and check that the door still moves evenly.
• Licensing. Under Arizona law (A.R.S. 32-1151), it is unlawful to act as or offer to act as a contractor without a license in good standing unless an exemption applies.
• Look it up. You can check a license in the Arizona Registrar of Contractors' online contractor search.
• Quotes. Arizona's insurance regulator (DIFI) notes it is your right to get more than one quote, and warns against high-pressure sales and door-to-door offers you did not ask for.
