Ensuring your automatic door regulations compliance

AUTOMATIC DOOR SERVICING

Mechanical doors, like any piece of moving mechanical equipment falls under the 2008 Machinery Directive. This basically states that the machine (in this case, the automatic door) should be routinely maintained on an on-going frequent basis. So, to ensure you’re staying compliant, make sure to book in your annual service. If you’re situated in a busy environment, think about making it every 6 months instead of 12.

Common Automatic Door Issues

Automatic Doors are designed for convenience, safety, and efficiency – but like any mechanical system, they can occasionally develop faults. Whether it’s a sensor malfunction, inconsistent movement, or a complete breakdown, knowing the common issues can help you identify problems early and avoid disruption. Below, we’ve outlined some of the most frequent faults encountered with commercial automatic doors, along with practical advice on what may be causing them and when to seek professional help.

Why won't my automatic door open when someone approaches?

There could be several reasons, including a faulty motion sensor, power supply issues, or a problem with the activation switch. Start by checking if the sensor is clean and unobstructed. If the door has a key switch or manual override, ensure it hasn’t been accidentally deactivated. If the issue persists, a deeper inspection of the control board or drive unit may be required.

My automatic door opens and closes repeatedly with no one nearby — what causes this?

This is typically caused by sensor misalignment, reflection from nearby surfaces, or movement detected within the sensor range (like swaying signage or plants). Check for reflective surfaces or motion near the entrance and reposition the sensor if needed. Faulty or overly sensitive sensors may also need replacing or recalibrating.

The door is moving slower than usual — is that a sign of a fault?

Yes, slow operation could indicate wear on the drive belt, resistance from the track, low motor power, or even software settings being out of calibration. It's also important to check for physical obstructions or lack of lubrication. The door could have also had a collision or thing it has had a collision - If not addressed, slow operation can lead to more serious mechanical failures.

One of the sliding doors isn’t moving, but the other is — what’s wrong?

This may be due to a disconnected or failed drive arm, an issue with the guide rail, or an obstruction preventing travel. It’s also possible that the motor is driving one leaf while the other is disengaged. In bi-parting systems, both doors should move together, so a technician should investigate linkage, belts, or control board output.

The door is making a grinding or unusual noise during operation — should I be concerned?

Unusual noises are often early signs of mechanical wear, such as a worn motor, dry bearings, or debris in the track. Grinding sounds can also indicate a misaligned guide rail or a failing drive unit. Continuing to use the door in this condition may lead to complete failure or safety risks.

My automatic door has stopped working after a power cut — what do I do?

Many automatic door systems need a manual reset after a power outage. Check if the control panel is receiving power and if a reset button or procedure is available. Some systems enter a safe mode and require professional attention to re-calibrate travel limits or restart sensor functions.

The emergency break-out function isn’t working — is this a safety issue?

Yes, this is critical. Break-out systems are designed to allow the door to swing open manually in emergencies. If this feature fails, it could be due to blocked pivot points, failed latching mechanisms, or incorrect reinstallation after servicing. Immediate professional assessment is recommended.

How can I tell if my automatic door needs servicing or repair?

Look for signs like inconsistent opening/closing, unexplained noises, delayed operation, or repeated sensor misfires. Regular servicing is essential to prevent breakdowns, meet safety compliance, and extend the lifespan of your system. If your door hasn’t been serviced in the past 6-12 months, it's due.

My swing door doesn’t respond to the push pad or touch sensor — what’s the issue?

Non-responsiveness is often due to electrical faults in the activation device (e.g., push pad, radar sensor), wiring issues, or faults in the door’s control board. Ensure the push pad has power and isn’t damaged. If it's hard-wired, test continuity; if wireless, check batteries or receiver pairing.
