Expert Automatic Door Repair in Croydon
Reliability is key for Croydon's corporate and retail sectors. Our independent engineers specialize in zero-downtime door solutions. As independent specialists, we work on all major brands including Dorma, Record, Geze, and Assa Abloy.
Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In Croydon, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
Swing Door Operator Tuning
We adjust latching action and backcheck on swing operators (like Record DFA 127). This ensures your Croydon door closes securely against wind pressure.
Solenoid Bolt Replacement
Security is vital. We replace failed electro-mechanical locks and solenoid bolts, ensuring your property in Croydon is 'Fail-Secure' every night.
Assa Abloy Error Codes
We diagnose sensor conflict errors on Assa Abloy sliding systems, resetting the learning cycle for smooth operation in Croydon.
Weather Mode Programming
Winter in Croydon is cold. We program 'Partial Open' modes (e.g., 50% width), keeping heat inside while allowing pedestrian access.
