Despite its ease of use, the roller shutter continues to attract a number of people. Whether for new construction or a renovation project, its installation is gaining ground.
Yet, its breakdown happens when you least expect it. The equipment refuses to go up. Faced with this situation, you no longer know who to turn to.
📋 📋 In brief: Personally, I consider that 80% of roller shutter blockages simply come from a misaligned slat or a broken curtain attachment inside the box. Before considering a complete replacement of the electric motor, a simple visual check of the guides often solves the problem. This methodical approach will save you from paying for unnecessary repairs for a fix that can be done in a few minutes.
Possible causes:
- Broken strap or crank (for manual models).
- Defective motor or power supply cut off (for electric models).
- Curtain out of the rails or stuck.
- Damaged or worn slats preventing proper rolling.
- Motor capacitor failure (often after several years of use).
- Obstacle or dirt in the box or guides.
How to bleed a heated floor? Faced with this problem, one calls a heating plumber. How to make a headboard? A carpenter is the ideal person to carry out this task.
However, when the roller shutter gets stuck, you feel a bit lost. This article helps you fix the issue without fuss.
🗣️ My experience: While trying to raise the PVC shutter in my living room last January, a dull rumble was heard and the curtain remained completely immobile. After opening the box, I discovered that frost had glued the last slat to the window sill, causing the rigid attachments connected to the axle to break sharply. The lesson learned is never to force the switch in winter if you feel mechanical resistance.
| Observed Problem | Probable Cause | Possible Solution |
|---|---|---|
| The strap no longer works | Wear or breakage | Replace the strap or the crank |
| The electric shutter does not respond | Power outage, motor failure, burnt capacitor | Check the power supply / replace the motor or capacitor |
| The shutter struggles to go up | Damaged slats or misaligned curtain | Repair or replace the slats |
| The shutter is stuck down | Curtain out of the rail or obstacle | Reinsert into the rails / clean |
| Abnormal noise at startup | Damaged mechanical part | Identify and replace the defective part |
🌍 Did you know? A standard roller shutter motor is designed to perform about 10,000 opening and closing cycles during its lifetime, which represents normal use without issues over an average period of 15 years.
The cause of a roller shutter that won’t go up
✅ Advantages
• Low cost when replacing individual component parts like capacitors or slats.
• Simple mechanical access once the shutter trunk cover is opened.
• Quick diagnostic procedures using basic electrical multimeters.
🔻 Weaknesses
• Working at heights creates safety risks on upper floor windows.
• Electrical hazards require cutting power at the main breaker.
• Risk of snapping brittle PVC slats when applying force.
To fix the malfunction, it is necessary to find its true cause. If you have a manual roller shutter, the failure may be due to a poorly adjusted crank.
Otherwise, the problem comes from the winding shaft. When its attachment is damaged or the slat is broken, it may block the shutter. It is also possible that the curtain receives repeated impacts. As a result, the shutter no longer works properly.
This incident can also be the result of a bent guide rail or a damaged strap. The latter case is common if the equipment lacks maintenance.
