Garage Door Repairs: 9 Common Problems and How to Fix Them

September 26, 2026
Garage Door Repairs

Garage doors are pretty simple from the outside but depend on a whole bunch of mechanical and electrical parts working together. Springs, cables, rollers, tracks, hinges, sensors and openers all have a vital part to play in safe and smooth operation.

When one of the components develops a fault, the door can become noisy, hard to open or completely stuck. Being aware of the common warning signs can help homeowners to spot a problem early and arrange the correct repair before a small fault turns into a much more expensive one.

Looking for Garage Door Repair in Dundee? Here are 9 common problems and practical solutions for each one.

Garage Door Will Not Open

There are many reasons a garage door won’t open. The problem might be a dead remote battery, power supply issue, faulty opener or safety sensor with an automated system.

First check that the opener has power and the remote is functioning. If the wall control does not operate the door either, you may need a professional diagnosis.

Never slam a heavy door, especially if a spring or cable appears broken.

Broken or Worn Springs

The garage door has springs that help balance the weight of the door. Repeated opening and closing can make them weak or break them over time.

If a spring breaks, the door may feel unusually heavy, move unevenly, or become difficult to lift manually.

A trained technician should perform the replacement of the spring. Springs store a lot of mechanical energy and can be dangerous to replace yourself.

Damaged or Misaligned Tracks

As the door travels the tracks guide the rollers. A bent, loose or unaligned track can cause the door to stick, scrape or move unevenly.

Look for any obvious obstructions, but do not try to straighten a badly damaged track yourself. A professional can inspect the track, rollers and mounting points and then make any needed adjustment or replacement.

Keeping the tracks clear of objects and clean will help prevent operating problems.

Worn or Damaged Rollers

As the door travels the tracks guide the rollers. A bent, loose or unaligned track can cause the door to stick, scrape or move unevenly.

Look for any obvious obstructions, but do not try to straighten a badly damaged track yourself. A professional can inspect the track, rollers and mounting points and then make any needed adjustment or replacement.

Keeping the tracks clear of objects and clean will help prevent operating problems.

Snapped or Damaged Cables

Springs and lifting cables raise and lower the door. One side of the door may drop or be uneven if the cable is broken or damaged.

DON’T try to pull or reposition a loose cable yourself. Poor handling can lead to damage and safety hazards.

If you see a cable dangling stop using the door and call for inspection.

Garage Door Is Stuck Halfway

Garage door rollers help the garage door to roll on the tracks. Worn rollers may cause grinding, squeaking or rattling noises.

A broken roller can also make the door hard to operate or cause it to move unevenly.

If the rollers show signs of wear, you can replace them to restore smooth movement. However, check the entire door mechanism for any related wear.

The Door Is Noisy

You will normally hear some operating noise, but do not ignore sudden grinding, banging, squealing or excessive vibration.

Possible reasons include:

  • Worn-out rollers
  • Hardware loose
  • Dry or worn out moving parts
  • Issues to Follow
  • Spring issues
  • Mistakes of the Opener

If the source is detected early, it can prevent further wear.

If you find that the noise persists despite performing basic maintenance, then professional Garage Door Repair in Dundee can identify the root cause rather than masking the symptom.

Garage Door Will Not Close Properly

If the automatic door opens normally but will not close, the safety sensors may not be working properly.

Make sure the sensor area is free of obstructions and wipe off dirt from the lenses that you can see. Also the sensors could have been misaligned.

Do not defeat or bypass safety interlocks. They are meant to stop the door from closing if something is in the way .

If the door still won’t close, have a professional check the opener and sensor system.

Remote Control Stops Working

Sometimes the problem is the remote, not the garage door.

First, change the battery. If the remote still does not work, try the wall-mounted control if you have one.

When the wall control operates the door, the issue may be with the remote or its programming. However, if neither control works, the opener may need further investigation.

When Should You Call a Professional?

However, garage doors contain heavy components and high-tension springs, so you should only perform simple checks that you can complete safely.

When professional assistance is advised:

  • A spring is broken.
  • The cable broke.
  • The door has come off its rail.
  • The door is unreasonably heavy.
  • The panels are badly cracked.
  • The starter has developed an electrical fault.
  • The door repeatedly breaks after repair.

Attempting to fix these problems without the right tools can cause injury or further damage.
