DOORLEC Product Lines We Repair
Our engineers are trained on the full DOORLEC product range. Below are the major product families we service.
DOORLEC Sliding Door Operators
AC/DC powered automatic sliding door operators for factory entrances, clean rooms, and production areas. Common issues include motor stall detection failures, sensor timeout errors, and brake relay malfunction causing doors to jam or fail-open.
DOORLEC Rolling Shutter Controllers
Programmable logic-based controllers for industrial rolling shutters and overhead security gates. Typical faults include limit switch interface failures, reversing contactors stuck in transition, and emergency stop circuit dropout.
DOORLEC Access Barrier Electronics
Integrated access control processor boards with proximity reader interfaces and gate actuation outputs. Common repair needs are card reader communication loss, solenoid latch driver burnout, and loss of 24V regulated supply to sensor circuits.
DOORLEC Safety Relay Modules
Safety-rated relay circuits for emergency stop and interlock functions in door automation systems. Frequent failures include trapped coil relay contacts, diagnostic output failure, and loss of safety monitoring signal causing automatic shutdown.
DOORLEC Motor Drive Boards
PWM and analog drive boards for DC and brushless motors powering door operators and gate mechanisms. Typical issues are MOSFET gate driver failure, current sense amplifier offset drift, and thermal shutdown cycling due to sensor malfunction.

Common DOORLEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOORLEC equipment arriving at our workshop.
- ✓Door operator motor stalls or reverses unexpectedly — DOORLEC door operators rely on precision motor current monitoring to detect obstruction and jam conditions. Failure of the current-sense amplifier IC on the motor drive board, or degraded filter capacitors reducing signal accuracy, cause false stall detection. Safety sensor misalignment also triggers erratic reversal.
- ✓Access barrier gate fails to unlock or opens slowly — DOORLEC ABX access barrier boards control solenoid latch actuation via dedicated driver transistors. Gate opening delay occurs when solenoid driver output stages degrade, electrolytic capacitors in the solenoid pull-in circuit age and lose capacitance, or the proximity card reader interface drops pulses causing incomplete unlock commands.
- ✓Rolling shutter controller limit switch input unresponsive — DOORLEC RSC shutter controllers process limit switch closure via opto-isolated input circuits to protect against electrical noise in heavy industrial environments. Opto-coupler failure, input conditioner IC degradation, or corroded reed switch terminals cause the controller to lose awareness of shutter position, preventing automatic stop and causing over-travel damage.
- ✓Safety relay module output does not energise or chatters continuously — DOORLEC safety relay modules enforce safety-rated stop commands via dual-channel relay contacts. Contact chatter and dropout result from trapped coil relay mechanism stiction, degraded armature return spring action, or AC supply voltage dip below rated minimum. Diagnostic output loss indicates failed status monitoring circuit.
- ✓Door operator responds slowly to open/close commands with lag — Slow response in DOORLEC sliding door operators indicates weak PWM drive signal delivery to the motor, caused by degraded PWM switching MOSFETs on the motor drive board, aged input coupling capacitors reducing signal amplitude, or microcontroller output pin failure reducing drive pulse current.
- ✓Access barrier system loses 24V regulated supply intermittently — DOORLEC ABX boards depend on a stable 24V regulated rail for all digital logic and sensor circuits. Intermittent supply loss stems from thermal shutdown of the linear regulator under solenoid load transients, aging filter capacitors losing capacitance during peak current draw, or cold solder joints on the power entry connector creating intermittent contact resistance.

Frequently Asked Questions — DOORLEC Repairs
Do you repair DOORLEC equipment anywhere in India?+
Yes. Synchronics repairs the complete DOORLEC product range including door operators, rolling shutter controllers, access barrier boards, safety relay modules, and motor drives across all of India. We operate PAN India pickup service from all major cities — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. All repairs are processed at our ISO-certified facility in Vadodara, Gujarat, with fast turnaround and comprehensive testing.
What is the typical repair time for a DOORLEC door operator board?+
DOORLEC door operator motor drive and control boards typically require 5-7 working days for diagnosis, component replacement, and full functional testing. Complex access barrier systems with multiple board failures may extend to 10 days. Synchronics prioritises critical production stoppage cases and offers expedited repair within 48-72 hours if arranged in advance. Exact timeline depends on component availability and fault complexity.
My DOORLEC sliding door operates intermittently — does Synchronics offer diagnostic support before repair?+
Absolutely. Synchronics provides free diagnostic assessment for all DOORLEC equipment. Our engineers perform non-destructive testing including electrical measurements, component tracing, and fault code analysis to identify root cause — whether motor stall detection error, sensor misalignment, or control board failure. We provide a detailed repair quotation and estimated timeline before any work begins. This reduces downtime guesswork for factory plant managers.
Can Synchronics repair DOORLEC access barrier boards used in Indian manufacturing plants?+
Yes. DOORLEC ABX and ABX-Pro access barrier boards are routinely repaired by Synchronics for Indian automotive, pharmaceutical, and logistics facilities. We specialise in solenoid driver repair, card reader interface restoration, 24V supply stabilisation, and proximity sensor signal conditioning. Many Indian factories depend on DOORLEC access systems for secure entry to restricted production and storage zones — Synchronics restores full functionality and access control integrity.
Does DOORLEC equipment require special test equipment or certification for repair in India?+
DOORLEC industrial door and access control equipment does not require formal certification in India, but Synchronics maintains rigorous quality standards. Safety relay modules are tested against relevant safety standards, and all motor drives are validated under actual load conditions using Synchronics test benches. We maintain full traceability of repairs and issue comprehensive test reports. For critical applications, Synchronics can provide additional documentation for compliance audits.
How do I send my DOORLEC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DOORLEC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DOORLEC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DOORLEC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
