Common Problems with Roller Doors and How to Fix Them

Roller doors are present in most homes and businesses. Garage doors, roller shutters, and security doors are popular choices for homes, while roller shutters, security doors, and doors are also popular choices for warehouses and stores. In any event, these doors are not exempt from problems. Normal wear and tear, environmental issues, and lack of maintenance can take their toll on the performance of such doors. For homeowners and would-be home and business operators, these problems can be as minor as an inconvenience or as severe as a security issue. 

Recognizing the most common door problems and how to fix them can save you time, money, and stress. Perhaps your door no longer opens, is making strange noises, or does not seem aligned. Issues like these usually have straightforward explanations and just as straightforward fixes. Of course, it is equally important to know when you can DIY and when you should leave it to professionals. You could easily make a problem much worse and effectively make matters worse for yourself and your safety or security.

The Door Will Not Open or Close

Problem: One of the most common door problems is not being able to completely open or close the door, which can occur because of some issues. Causes:

• Blockage in the tacks

• Faulty motor (if automatic)

• Broken springs and cables

• Tracks not aligned

Fix: 

• First things first - check for any physical issue with blockage in the track or at the bottom.

• For automatic doors, check to see if the remote or wall switch works and that the motor is getting power.

• If manual, check tension spring and cables - do not attempt to fix yourself if you don't know what to do as these are under a lot of tension.

If your tracks are misaligned, you may be able to align them using a wrench; otherwise, your door may be seriously warped, and you need a professional.

Noisy Operation

Problem: Squeaking, grinding, or rattling sounds during operation can indicate mechanical issues. Causes:

• Lack of lubrication

• Loose hardware

• Debris in tracks

• Worn-out rollers or hinges

Fix:

• Lubricate moving parts using silicone spray or garage door lubricant (avoid WD-40 as it can attract dust).

• Clean tracks thoroughly.

Door Stuck Half Open/Half Closed 

Problem: The Roller Doors are stopping halfway on opening or halfway on closing. Causes:

• Obstruction/debris/damage to track

• Faulty limit settings (in automatic doors)

• Broken torsion springs

• Motor issues

Fix:

• Clear visible debris/dirt from tracks

• For automatic systems: see the owner's manual and reset (or adjust) limit settings

• If spring is broken or sagging (visibly), consult a service professional. Attempting a spring repair yourself can be dangerous.

Remote Control Not Responding

Problem: The Remote is not working for the doors. Causes:

• Dead batteries

• Remote is out of sync

• Signal interference

• Faulty receiver

Fix:

• Replace the remote’s batteries.

• Reprogram the remote according to the user manual.

• Ensure there's no radio interference in the area.

The Roller Door Is Off the Track

Problem: Garage doors do not operate properly. Causes:

• Impact damage (e.g., vehicle hitting the door)

• Loose or broken rollers

• Bent or misaligned tracks

Fix:

• Inspect the track and rollers.

• Minor adjustments can be made by realigning the track and tightening bolts.

• Significant misalignment or damage requires a trained technician to avoid worsening the issue.

Sluggish or Uneven Movement

Problem: The roller door operates very slowly or appears to be leaning while in use. Causes:

• Dirty or damaged rollers.

• Out of balance springs.

• Worn motor.

Fix:

• Clean or replace any dirty rollers.

• For motor issues, if it’s an older unit, you may need to service or replace it.

Sagging or Warping Door Panels

Problem: Over time, some quality garage doors, particularly older or cheaper models, may begin to sag or warp. Causes:

• Age and material fatigue

• Exposure to heat, sun, or moisture

• Poor-quality manufacturing

Fix:

• To prevent sagging, ensure regular lubrication and maintenance.

Roller Door Reverses Immediately

Problem: The door begins to close, but then reverses without touching anything.

Causes:

• Faulty or misaligned safety sensors

• Sensor lenses blocked by dust or debris

Fix:

• Clean the safety sensors using a soft cloth.

• If sensors appear damaged, have them inspected or replaced by a professional.

Maintenance Tips for Longer Roller Door Life

• Lubricate: Every 3–6 months, lubricate all moving parts, including rollers, hinges, and springs.

• Clean Tracks: Regularly remove dirt, cobwebs, and other debris from the tracks.

• Test Balance: Periodically test the door’s balance by disconnecting the opener and manually lifting it halfway.

• Professional Checkup: Schedule an annual inspection with a roller door technician to catch issues before they become major problems.
