Detailed Technical Diagnostics & Motor Repair in Harefield

Modern automatic doors are sophisticated electro-mechanical systems driven by complex logic controllers. When we attend a breakdown in Harefield, we do not simply apply a quick patch; we perform a full **technical diagnostic audit**. This involves a granular inspection of the **brushless DC motor gearbox** for internal wear, testing the **drive belt tension** for signs of fatigue, and analysing the **control board error logs** for historical fault codes.

Common issues we encounter in Harefield include worn carriage wheels causing doors to jump off their top tracks, and faulty encoder signals leading to erratic, jerky movement. Our technicians utilise specialist handheld programming terminals to recalibrate opening speeds, hold-open times, and braking forces, ensuring your door operates smoothly, silently, and efficiently.

Serving Harefield's Retail Sector

For shops and supermarkets in Harefield, a working door invites customers in. We prioritize retail repairs, offering out-of-hours service to minimize disruption to your trading. We handle heavy-duty sliding doors capable of withstanding constant footfall.

Types of Automatic Doors We Repair in Harefield

Our engineering expertise covers the full spectrum of automation technologies found in Harefield. We regularly service and repair:

• Automatic Sliding Doors: Single and bi-parting sliders are common in Harefield supermarkets and retail entrances. We fix worn carriage wheels, snapped drive belts, and misaligned bottom guide tracks.
• Automatic Swing Doors: Widely used in Harefield offices and for disabled access (DDA) toilets. We repair the arm linkages, spring tensioners, and hydraulic damping systems.
• Telescopic Doors: Ideal for narrow entrances in Harefield, these complex mechanisms require precise alignment of the multi-leaf drive belt system to function correctly.
• Revolving Doors: We service the speed control governors and collapsible wing mechanisms for high-prestige entrances.

BS EN 16005 Safety Compliance: Your Legal Duty in Harefield

Safety is our absolute top priority. All automatic doors in Harefield must strictly adhere to the **BS EN 16005** safety standard (formerly BS 7036). Operating a non-compliant door puts your staff and visitors at risk of impact or crushing injuries and exposes your business to significant liability. During every service visit to Harefield, our engineers conduct a mandatory safety assessment.

We test the **static closing force** to ensure it does not exceed 150N, preventing injury to vulnerable users. We verify that all **safety sensors** (both activation radars and presence detection beams) are functioning correctly and cover the entire door travel area. If your door in Harefield lacks essential safety features like finger guards or monitored safety beams, we can retrofit modern safety devices to bring your system up to current legal standards.

The Value of Planned Maintenance in Harefield

Reactive repair is often more costly than proactive care. We recommend our **Planned Preventative Maintenance (PPM)** service for all businesses in Harefield. Regular servicing (typically twice a year) allows us to clean the bottom guides, tighten drive belt tension, and lubricate the gearbox. This prevents the common 'grinding' failures we see in Harefield and significantly extends the lifespan of your expensive automatic door assets.

Common Automatic Door Faults We Fix

In Harefield, we frequently resolve issues such as:

• Door stuck open or closed: Often caused by dirty sensors or power failure.
• Noisy operation: Indicates worn floor guides or motor bearings.
• Erratic movement: Usually a sign of encoder errors or belt slippage.
• Failure to lock: We adjust electric strikes and maglocks for secure locking.
