10 Reasons Your Roller Shutter Won’t Close (And How to Fix Them)

faulty roller shutters

We’ve all been there: you’re about to lock up for the day, or perhaps you’re just trying to secure your home, and your roller shutter refuses to cooperate. Such moments can be frustrating, but understanding the potential causes can help you address the issue effectively. Let’s explore the top 10 reasons your roller shutter might not be closing and how to tackle them.

1. Obstructed Path

Problem: One of the most common reasons a roller shutter won’t close is something obstructing its path.

Solution: Ensure the tracks on both sides are free from debris or objects. Regularly cleaning the tracks can help prevent this issue.

2. Motor Issues

Problem: If your shutter is motorised, there’s a chance the motor has worn out or malfunctioned.

Solution: Check for any unusual sounds or lack of response when trying to activate the shutter. If you suspect a motor issue, consult with a professional for repairs or replacements.

3. Misaligned Tracks

Problem: Over time, the tracks of the roller shutter can become misaligned due to wear and tear or accidental force.

Solution: Visually inspect the tracks. If they appear bent or out of place, they might be causing the shutter to get stuck. You’ll need to realign them, and in some cases, you might need to replace them entirely.

4. Worn-Out Tension Springs

Problem: Roller shutters operate with the help of tension springs. If these springs wear out or break, the shutter won’t close properly.

Solution: Check the tension springs for any signs of wear or breakage. Replacing them might require professional assistance as they are under high tension and can be dangerous if not handled correctly.

5. Remote Control Malfunction

Problem: For automated roller shutters, a malfunctioning remote control can be the culprit.

Solution: Ensure the remote’s batteries are fresh. If that doesn’t solve the problem, check for possible interference with the signal or consider getting a replacement remote.

6. Manual Override Engaged

Problem: Some roller shutters come with a manual override for situations where power is unavailable. If this is engaged by mistake, the motorized function won’t work.

Solution: Check your user manual on how to disengage the manual override. Usually, it’s a switch or button on the motor or control panel.

7. Electrical Issues

Problem: If there’s a problem with the power source, your motorized shutter will not function.

Solution: Ensure that the roller shutter is properly plugged in and the power source is active. Check circuit breakers, and consider consulting an electrician if power issues persist.

8. Faulty End Limit Settings

Problem: Roller shutters often have end limit settings that determine their open and closed positions. If these are set incorrectly, the shutter might not close fully.

Solution: Refer to your user manual on how to adjust the end limit settings. If unsure, it might be best to call in a professional to avoid potential damage.

9. Locks or Shutter Latches Engaged

Problem: Some roller shutters have locks or latches to enhance security. If these are inadvertently engaged, the shutter won’t move.

Solution: Ensure all locks, latches, or security mechanisms are fully disengaged before attempting to close the shutter.

10. Wear and Tear

Problem: Like all mechanical devices, roller shutters have a lifespan. General wear and tear can cause them to malfunction.

Solution: Regular maintenance can extend the life of your roller shutter. However, if the shutter is old and frequently malfunctions, consider replacing it for better functionality and enhanced security.

While roller shutters are designed for durability and longevity, issues can arise from time to time. By understanding the potential problems and their solutions, you can ensure that your roller shutter continues to serve its purpose effectively. Always remember, when in doubt, consulting with a professional roller shutter technician can save you time, money, and potential hazards.
