How to Repair a Roller Shutter Winder Box

The roller shutter winder box is an essential component of manual roller shutters, housing the mechanism that winds the shutter strap. Over time, this box can develop issues that affect the smooth operation of your shutters.

While it might seem like a straightforward DIY task, repairing a roller shutter winder box can be quite complex and time-consuming, especially for Sydney residents who are not familiar with the intricate workings of these systems. Here’s a detailed guide on the process, but remember, the best option is often to call in the professionals at Fix My Shutters.

Step 1: Gather Your Tools and Materials

Before you start, you’ll need a range of tools and materials, including:

Screwdriver: To remove screws and access the internal mechanisms.

Replacement Strap: If the strap is worn or broken.

Lubricant: To ensure smooth operation of moving parts.

Cleaning Cloth: To remove dust and debris.

Ladder: If the winder box is located at a height.

Finding the right parts and tools can be challenging and time-consuming, especially if you’re not sure exactly what you need.

Step 2: Ensure Safety

Secure the Area: Make sure the area around the winder box is clear of any obstacles.

Turn Off Power (if applicable): If your roller shutter has an electric component, ensure the power supply is turned off to avoid any accidental activation.

Ensuring safety while handling potentially hazardous components is crucial and can be tricky without the proper experience.

Step 3: Access the Winder Box

Remove the Cover: Use a screwdriver to remove the screws holding the winder box cover in place. Carefully lift off the cover to expose the internal mechanism.

Inspect the Components: Take a close look at the strap, winding mechanism, and other components to identify any visible issues such as wear, damage, or debris.

Accessing and diagnosing issues within the winder box requires a keen eye and a good understanding of the mechanism, which can be overwhelming for those unfamiliar with it.

Step 4: Remove the Old Strap (if necessary)

Detach the Strap from the Roller: Locate where the strap is attached to the roller and remove any securing pins or screws.

Unwind the Strap: Carefully unwind the strap from the winder mechanism, taking note of how it is threaded through any guides or channels.

Removing the old strap without damaging other components requires precision and patience, something best left to experienced professionals.

Step 5: Clean and Lubricate

Clean the Mechanism: Use a cleaning cloth to remove any dust, dirt, or debris from the internal components of the winder box.

Apply Lubricant: Apply a silicone-based lubricant to the moving parts of the winder mechanism to ensure smooth operation. Avoid using oil-based lubricants as they can attract more dirt.

Proper cleaning and lubrication are crucial for the longevity of the winder box but can be easily mishandled without proper knowledge.

Step 6: Install the New Strap (if necessary)

Measure and Cut the New Strap: Ensure the new strap is the correct length and cut it to size if necessary.

Thread the Strap through the Guide: Carefully thread the new strap through any guides or channels, following the same path as the old strap.

Attach the Strap to the Roller: Secure the new strap to the roller using the appropriate pins or screws.

Installing the new strap correctly is a delicate process that requires accuracy to ensure smooth operation.

Step 7: Reassemble the Winder Box

Wind the Strap: Wind the new strap onto the winder mechanism, ensuring it winds smoothly and evenly.

Replace the Cover: Reattach the winder box cover and secure it with the screws you removed earlier.

Reassembling the winder box incorrectly can lead to further issues, making professional assistance a safer bet.

Operate the Shutter: Test the roller shutter by raising and lowering it several times to ensure the winder box is functioning correctly.

Check for Smooth Operation: Ensure the shutter moves smoothly without any jerks or unusual noises.
