Signs your garage door needs repair, and signs it needs it now

Updated November 10, 2026 · KeystoneProGuide editorial team

How can you tell that a garage door needs repair?

By how it sounds, how it moves, how it looks and whether it passes its monthly safety test. Most signs mean a visit should be booked. A few mean the door should not be used at all until someone trained has looked at it. This guide sorts them into those two groups and adds a third: things that look like faults and are not.

Which signs mean you should stop using the door now?

The door is partly open and crooked. Angi's advice is blunt: do not touch it. A door stuck at an angle points to a cable problem, the door is probably still under spring tension, and a wrong move could bring a 200-pound door down.
You heard a bang and the door is suddenly heavy. HomeGuide describes a breaking spring as a sudden gunshot-like bang, and This Old House lists a loud pop followed by a door that feels extremely heavy. A visible gap in the coils of the spring above the door is another sign.
A cable is frayed, slack or hanging. DASMA, the door manufacturers' trade association, says frayed or worn cables are in danger of breaking, which can cause injury. Fixr adds that loose, dangling cables are one of the signs of a broken spring.
The door drops or slams, or will not stay open. Both appear on the lists of spring failure signs published by HomeGuide and Angi. IDA says a door that does not stay open when lifted may be out of balance.
The door does not reverse when it meets an obstacle. The Consumer Product Safety Commission says that if a door fails to reverse promptly on striking a block of wood, the opener should be disengaged and a service technician called.
The opener runs but the door does not move. Angi says that usually means a broken cable or spring. Fixr suggests one check first: the door may simply have been locked by hand.

While a door is in any of these states, keep people and cars out from under it. The federal safety standard for openers requires every manual to carry the instruction never to go under a stopped, partially open door.

Which signs mean you should book a visit soon?

Grinding, scraping or rattling. The International Door Association (IDA), the door dealers' trade body, reads the sounds this way: grinding can mean worn rollers or hinges, rattling can mean loose nuts or bolts, and popping could suggest a broken spring. Angi adds debris caught in the tracks to the causes of grinding.
Slow, jerky or uneven movement. Angi puts it down to loose bolts, opener forces that need adjusting or too little lubrication. IDA says a door that jerks, shakes or stops short may be off its track or have a cable problem.
The door feels heavy when you lift it by hand. DASMA says a door that needs two hands is probably out of balance, and that the answer is an adjustment by a technician and not a more powerful opener.
The door will not close fully, or reverses for no clear reason. HomeGuide says a faulty sensor can make the door stop or reverse unexpectedly. Clean and check the photo eyes first; if the problem stays, it needs a technician.
The door opens or closes by itself. Fixr calls this a real security risk and lists wiring, the sensors, broken springs and the opener among the possible causes.
Visible damage. IDA's inspection routine looks for split or cracked panels, bent hinges, missing bolts, heavy rust and gaps between panels. HomeGuide adds visible damage to cables, springs or tracks.

HomeAdvisor's advice applies to this whole group: schedule service as soon as you hear grinding or see uneven movement, before a small problem grows.

Which signs are usually not a fault?

Squeaky springs. DASMA says springs can squeak with normal use and that this does not necessarily indicate a problem. Its first step is a spray lubricant made for garage doors, and a service call only if the noise persists.
A slow door on a very cold morning. Angi notes that extremely low temperatures can affect how the system performs, and suggests waiting until the garage warms up before deciding something is wrong.
A remote that has stopped working. Fixr says that nine times out of ten the remote only needs new batteries.
A door that goes back up in bright sun. Angi says sunlight striking a sensor lens at a certain angle can do this, and that shading the lens with your body is a quick way to check.

What does the age of the parts tell you?

Age is a sign in its own right, because the working parts are rated for a set amount of use.

Springs. This Old House says they typically last 7 to 12 years. Fixr says a spring should last at least 10,000 cycles, a cycle being one opening and closing.
Cables. Fixr gives approximately 8 to 15 years.
Openers. Fixr and HomeGuide both give 10 to 15 years.
The door itself. HomeAdvisor says most doors last 15 to 30 years.

An opener's age matters for safety as well as wear. DASMA says that since 1993 every opener made for the United States must have a second reversing feature such as photoelectric eyes, and that an opener without one should be replaced. The date of manufacture is marked on the unit.

What should you do when you see one of these signs?

Write down what the door does and when. Angi suggests making a note of the symptoms, such as loud bangs, uneven movement or difficulty opening, to give to the technician. Then decide how urgent it is. A sign from the first list is a reason to leave the door alone and call; a sign from the second can wait for a normal appointment.

Before you pick up a tool, read which garage door repairs are safe to do yourself: the answer for springs, cables and bottom brackets is none. The cost guide gives the published price range for each repair, and companies that do the work are on the garage door repair directory page.
