How to Fix a Jammed Roller Shutter

A jammed roller shutter can be a frustrating problem, compromising both the security and convenience of your home or business. Fortunately, many issues that cause shutters to jam can be resolved with some basic troubleshooting and maintenance.

Here’s a detailed guide on how to fix a jammed roller shutter:

Step 1: Identify the Problem

Before you can fix a jammed roller shutter, you need to determine what’s causing the issue. Common causes include:

Debris or Dirt: Accumulation of dirt, dust, or debris in the tracks can obstruct the shutter’s movement.

Misaligned Tracks: Tracks that are bent or misaligned can cause the shutter to jam.

Damaged Slats: Bent or broken slats can prevent the shutter from moving smoothly.

Motor Issues: For electric shutters, motor malfunctions can lead to jamming.

Worn Straps or Cables: Frayed or broken straps or cables can also cause operational issues.

Step 2: Gather Your Tools and Materials

Depending on the problem, you may need the following tools:

Screwdriver: For opening the shutter box and adjusting parts.

Lubricant Spray: To lubricate the tracks and moving parts.

Soft Brush or Cloth: For cleaning debris from the tracks.

Replacement Parts: Such as slats, straps, or cables if any are damaged.

Ladder: To reach higher sections of the shutter.

Step 3: Ensure Safety First

Turn Off Power: If your roller shutter is electric, switch off the power supply to avoid any accidental activation.

Secure the Area: Make sure the area around the shutter is clear of any obstacles or hazards.

Step 4: Clean the Tracks

Remove Debris: Use a soft brush or cloth to clear any dirt, dust, or debris from the tracks. This can often resolve jamming issues.

Lubricate the Tracks: Apply a silicone-based lubricant spray to the tracks to ensure smooth movement. Avoid using oil-based lubricants as they can attract more dirt.

Step 5: Check and Adjust the Tracks

Inspect for Misalignment: Examine the tracks for any bends or misalignments. If you find any, gently straighten them using a pair of pliers or a similar tool.

Secure Loose Tracks: Ensure the tracks are securely fastened to the wall or frame. Tighten any loose screws or bolts.

Step 6: Inspect and Repair Slats

Examine Slats: Look for any bent or broken slats that could be causing the jam.

Replace Damaged Slats: If you find any damaged slats, replace them with new ones. This may involve removing screws or clips that hold the slats in place.

Step 7: Test the Shutter Manually

Manually Operate the Shutter: Gently try to raise and lower the shutter manually to see if it moves smoothly. If it does, the problem may have been resolved by cleaning and lubricating.

Step 8: Address Motor Issues (for Electric Shutters)

Check the Motor: If the shutter still jams and it’s electric, the issue might be with the motor. Listen for any unusual noises or check for overheating.

Reset the Motor: Some motors have a reset button. Refer to the manufacturer’s manual for instructions on how to reset the motor.

Call a Professional: If the motor appears to be damaged or malfunctioning, it’s best to contact a professional technician for repairs.

Step 9: Replace Worn Straps or Cables

Inspect Straps or Cables: Look for any fraying, stretching, or breaking.

Replace if Necessary: If the straps or cables are worn out, replace them with new ones following the manufacturer’s instructions.

Step 10: Perform a Final Check

Test the Shutter: After making the necessary repairs, test the shutter again by raising and lowering it several times. Ensure it moves smoothly without jamming.

Check for Consistency: Ensure the shutter operates consistently and there are no recurring issues.


Fixing a jammed roller shutter can often be managed with some basic troubleshooting and maintenance. By identifying the cause of the jam and following these steps, you can restore your shutter’s smooth operation.
