How do I identify the correct parts for my roller shutter door?

Identify the door manufacturer from the label or data plate (common UK brands include Hörmann, Novoferm, Garador, Gliderol, Cookson and SWS). The model number will be on the data plate. Key specifications to know are door width, barrel diameter, spring specs and motor make/model if motorised.

How often do roller shutter springs need replacing?

Torsion springs are rated by number of cycles — typically 10,000-25,000 cycles for standard springs. A daily-use commercial door cycling 5 times per day reaches 10,000 cycles in approximately 5.5 years. Signs of wear include increasing effort to open or the door not staying open.

Can I replace a roller shutter spring myself?

Roller shutter torsion springs are under very high tension and can cause serious injury or death if released incorrectly. Spring replacement should only be carried out by trained shutter door engineers. We strongly advise against DIY spring replacement without proper training and tools.

What causes a roller shutter motor to stop working?

Common faults include: tripped thermal overload in the motor, limit switch misalignment, worn brushes or capacitor failure, damaged control board or transformer, and faulty radio receiver or transmitter. Many faults can be diagnosed with a multimeter by a competent electrician.

What maintenance do roller shutter doors require?

Monthly: visual inspection of guides, springs, curtain slats and locking bars. Lubricate guides, barrel bearings and all pivot points. Annually: thorough inspection of all mechanical components, spring tension check, motor current draw test, and test all safety edges and photocells.
