Expert AKO controller and transmitter repair with 30 years' proven service record.
AKO Product Lines We Repair
Our engineers are trained on the full AKO product range. Below are the major product families we service.
AKO Temperature Controllers (Compact & Modular)
AKO's flagship temperature control range including single/multi-loop controllers with analog and digital inputs. Common failures: display malfunction, setpoint drift, relay chatter, sensor input errors, and firmware corruption in networked variants.
AKO Pressure & Level Transmitters
4-20mA and 0-10V output transmitters for process monitoring. Typical issues: zero/span drift, signal loss, connector corrosion, damping circuit failure, and enclosure seal degradation in humid environments.
AKO Process Automation Modules (PAC)
Standalone and networked process control modules with analog I/O, communication interfaces (Modbus, Profibus), and logic sequencing. Repair challenges: communication failures, input/output card faults, power supply degradation, and industrial noise immunity issues.
AKO Limit Controllers & Alarm Units
Single-setpoint and multi-level alarm controllers for overpressure, overtemperature, and underprocess protection. Common faults: relay contact wear, hysteresis drift, solenoid circuit failure, and enclosure corrosion in washdown areas.
AKO Networked Control Systems (Modbus/Profibus-enabled)
Integrated multi-loop control platforms with real-time data logging and remote monitoring. Typical failures: communication gateway malfunction, protocol conversion errors, real-time clock battery failure, and SD card corruption.
Why Choose Synchronics for AKO Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on AKO equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AKO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AKO equipment arriving at our workshop.
- ✓AKO temperature controller display goes blank — LCD segment failure or internal voltage regulator degradation. Common in older AKO 14/16 controllers after 8-10 years of operation, especially in high-temperature mounting environments (>50°C ambient).
- ✓AKO transmitter zero/span drift over time — Capacitive sensor aging, amplifier IC drift, or 4-20mA output circuit component fatigue. Particularly frequent in pharmaceutical and food processing plants where transmitters operate continuously without seasonal shutdown.
- ✓Relay chatter and contact erosion in AKO controllers — Insufficient contact bounce suppression (software timing), electromagnetic interference from nearby VFDs/soft starters, or worn mechanical relay contacts after high-cycle operation (>100K cycles).
- ✓AKO Modbus/Profibus gateway communication timeout — Firmware bugs in older AKO network modules, baud rate mismatch, cable impedance issues, or CRC checksum errors due to industrial noise in the manufacturing environment.
- ✓Sensor input not recognized in AKO multi-loop controller — Input amplifier IC failure, faulty analog-to-digital converter (ADC), corroded terminal block contacts, or incorrect input range configuration after firmware update.
- ✓AKO controller enclosure moisture ingress and corrosion — Degraded gaskets, loose cable glands, condensation from thermal cycling in humid Indian climates (coastal/monsoon regions), or inadequate ventilation in panel-mounted installations.

Frequently Asked Questions — AKO Repairs
Do you repair AKO equipment anywhere in India?+
Yes. Synchronics repairs the full AKO product range — temperature controllers, pressure transmitters, process automation modules, and networked control systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Bangalore, and all other major cities. All equipment is repaired at our certified facility in Vadodara, Gujarat, with expedited return logistics.
What is your turnaround time for AKO controller repair?+
Standard turnaround is 5-7 working days after receipt of equipment. For critical production-line shutdowns, we offer priority 48-hour repair with advance notice. Turnaround time depends on parts availability and fault complexity. We provide daily repair status updates and can arrange courier dispatch the same day repair is complete.
Do you provide calibration certificates for repaired AKO transmitters?+
Yes. All AKO transmitters repaired at Synchronics are calibrated using NIST-traceable instrumentation and supplied with an official calibration certificate. Certificates include as-found/as-left readings, calibration date, next calibration recommendation, and engineer details. This satisfies FDA, ISO 9001, and Indian pharmaceutical compliance audits.
Can you repair AKO controllers with obsolete firmware or communication modules?+
Yes. Synchronics maintains archives of AKO firmware versions dating back to the 1990s. We can reprogram obsolete communication modules (older Profibus, custom serial protocols) or upgrade to modern standards like Modbus TCP where hardware compatibility allows. We test extensively before returning equipment to ensure zero process interruption.
What happens if an AKO component cannot be repaired?+
If repair is not economically viable, Synchronics sources original AKO replacement modules or OEM-equivalent industrial-grade components at competitive pricing. We facilitate seamless drop-in replacement, perform bench commissioning, and provide written technical handover to your maintenance team. No hidden charges — all options quoted upfront.
How do I send my AKO 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 AKO 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 AKO 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 AKO 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.
