KONE Equipment We Repair — By Category
KONE Product Lines We Repair
Our engineers are trained on the full KONE product range. Below are the major product families we service.
KONE Lifts - Modernization Control Systems
KONE lift modernization boards manage motion control, door operation, and traffic management. Common issues include relay module failures, communication board faults, and power supply degradation affecting lift acceleration and stopping precision.
KONE Automatic Door Operators
KONE automatic sliding door systems used in hospitals, malls, and offices across India. Repair issues include sensor interface failures, motor driver faults, power module breakdowns, and RF communication losses between remote control and door receiver.
KONE Escalator Control Electronics
Escalator speed control, safety brake circuits, and passenger detection systems. Common faults include frequency converter failures, safety relay malfunctions, and variable frequency drive (VFD) issues causing speed inconsistency or emergency stops.
KONE Lift Door Operators - Drive Electronics
Door opening and closing motor drivers, position sensors, and synchronization controllers. Typical failures involve IGBT module damage, gate driver circuit malfunction, and encoder signal loss affecting door timing.
KONE Power Supply Modules
Industrial-grade 24VDC and 48VDC power supplies with backup battery charging circuits. Failures include capacitor aging, regulator IC breakdown, and transformer winding faults leading to control system shutdown.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common KONE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KONE equipment arriving at our workshop.
- ✓KONE lift controller communication bus failure — Damaged CAN bus or proprietary KONE protocol communication board due to electrical noise in multi-floor installations or age-related PCB corrosion in Indian humid environments.
- ✓Automatic door operator motor driver short circuit — KONE door operator MOSFET or IGBT gate driver circuit fails due to high inrush current during door opening cycles or moisture ingress in coastal Indian installations.
- ✓KONE lift emergency brake relay malfunction — Safety-critical brake hold relay coil winding breaks or armature becomes stuck due to dust accumulation in industrial environments, causing lift safety failures.
- ✓Escalator frequency converter overvoltage fault — KONE escalator VFD output stage capacitors degrade in high-temperature Indian summer conditions or DC bus voltage regulation fails, triggering overvoltage protection trips.
- ✓Door position sensor (inductive proximity) signal loss — KONE inductive sensor connector corrosion, broken signal cable, or sensor IC malfunction in KONE automatic door systems prevents door limit detection.
- ✓KONE lift power supply brownout shutdown — Electrolytic filter capacitors age or fail, reducing hold-up time during mains voltage sags common in Indian industrial estates, causing repeated lift control system resets.

We have diagnostic software access and can reprogram KONE controllers if needed. Our engineers understand KONE's proprietary MonoSpace and DX series protocols.
How long does KONE automatic door operator repair typically take?+
Most KONE door operator electronics repairs (motor drivers, position boards, sensor interfaces) are completed within 3-5 working days. For critical installations like hospital entry doors or mall entrances, Synchronics offers expedited 24-48 hour turnaround with loaner units available to minimize facility downtime.
Can you repair KONE escalator VFD drives in India?+
Yes. Synchronics specializes in KONE escalator and moving walkway frequency converters. We replace failed IGBT modules, repair DC bus capacitor banks, recalibrate voltage feedback circuits, and perform full load testing. We work on KONE TransitMaster, TravelMaster, and EcoMaster series escalator drives.
Do you offer KONE lift controller firmware updates or reprogramming?+
Yes. Synchronics can reprogram KONE lift controllers and update firmware when needed for feature enhancement or fault recovery. We maintain compatibility with KONE's latest parameter sets and ensure all safety interlocks remain functional per Indian elevator safety regulations.
How do I send my KONE unit for repair?+
