If an automatic gate moves unexpectedly, has visible damage or does not respond safely, keep people clear and follow the manufacturer's instructions for taking it out of use. Do not bypass sensors or increase operating force to overcome a fault.

Record the symptom precisely
Note whether the problem affects opening, closing or both; whether it happens with every control; and whether the display or indicator shows a code. Record when it started and whether there was a power interruption, impact or other relevant change.
Keep the model details and manuals available. A video taken from a safe position can help explain an intermittent symptom, but do not repeatedly operate an unsafe gate just to capture it.
Use only the checks specified for the user
Consult the troubleshooting section of the exact manual. A flat remote-control battery, loss of supply, obstructed sensor or mechanical problem can produce different symptoms. The manual determines which checks a user can perform and when professional service is needed.
Do not open electrical enclosures, bridge terminals or defeat a safety device using a general internet procedure. Stay clear of moving and stored-energy components. Use emergency release only according to the documented procedure and conditions.
Give the technician useful information
- Opener model and gate type.
- The exact fault or error code.
- Which controls and operating directions are affected.
- Any recent damage, power interruption or maintenance.
- Previous work and available installation documents.
Repair or replacement?
Have the cause assessed before ordering a replacement motor. The problem may involve the gate, power system, controller, sensor or another component. A new motor does not correct an unsuitable installation or mechanical defect.
If replacement is recommended, compare compatible gate opener options with the technician's specification. Confirm the safety and control components that will be retained or replaced, and keep the new handover and maintenance information.
