KOHLER Product Lines We Repair
Our engineers are trained on the full KOHLER product range. Below are the major product families we service.
Kohler Diesel Generator Sets (60-1250 kVA)
Heavy-duty diesel gensets for industrial backup power and continuous duty applications. Common repair issues include fuel system blockages, turbocharger surging, governor hunting, exhaust manifold cracks, and fuel injection pump degradation affecting load response and frequency stability.
Kohler Automatic Transfer Switches (ATS)
Critical power switching systems for seamless utility-to-generator transitions. Repairs focus on contact erosion, phase voltage sensing failures, neutral grounding issues, mechanism sluggishness, and microprocessor control board faults causing transfer delays or refusal to switch.
Kohler Voltage Regulation Systems (AVR)
Automatic voltage regulators maintaining output stability under variable load conditions. Typical faults include capacitor leakage, sensing transformer degradation, thyristor firing circuit failures, and potentiometer drift causing under-voltage or over-voltage conditions.
Kohler Engine Governors and Speed Control
Mechanical and electronic governors regulating engine RPM and frequency under dynamic load changes. Common failures include fuel rack linkage stiction, governor spring fatigue, solenoid coil burn-out, and electronic speed sensor malfunction causing frequency drift and load-sharing errors.
Kohler Control Panels and Monitoring Systems
Digital and analog control interfaces for genset operation, synchronization, and protection. Repair includes LCD display dead pixels, digital communication module failures, CT secondary open circuits, and relay contact replacement for alarm and shutdown sequences.
Kohler Fuel Injection and Engine Electronics
Common rail fuel systems and engine management electronics ensuring efficient combustion and emissions compliance. Repairs address fuel injector nozzle deposits, high-pressure pump seizure, electronic control unit (ECU) programming loss, and fuel metering valve calibration drift.

Common KOHLER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KOHLER equipment arriving at our workshop.
- ✓Genset fails to pick up load smoothly — Kohler engine governors experience fuel rack hunting or governor spring relaxation over years of continuous duty operation, particularly in textile mills and steel foundries running 20+ hour daily cycles. Load transient response degrades when damping components wear.
- ✓Automatic Transfer Switch (ATS) refuses to transition — Kohler VATS contactors suffer contact erosion from arc suppression failures or microprocessor sensing circuit faults misreading incoming utility voltage. Neutral grounding relays may stick due to coil insulation breakdown or debris in switching mechanism.
- ✓Alternator output voltage sagging under load — Kohler AVR capacitor banks degrade in humid Indian warehouse environments (40-50°C ambient, high moisture during monsoon). Sensing transformer core saturation or regulator potentiometer drift causes under-voltage regulation below 400V nominal output.
- ✓Engine speed oscillates (hunting) at light load — Woodward or Bosch governor solenoid coil insulation failure, or mechanical hunting due to governor spring preload loss in Kohler gensets after 5000+ operating hours. Electronic isochronous controllers may experience sensor noise immunity issues in EMI-heavy mill environments.
- ✓Fuel injectors misfiring, rough idle, black smoke — Kohler common rail fuel systems suffer injector nozzle carbon deposit buildup from high-sulphur Indian diesel or fuel pump cavitation during prolonged low-load operation. ECU fuel map calibration may corrupt from power supply surges during grid switching transients.
- ✓Control panel LCD frozen or alarm relay stuck — Kohler DCP or iCommand panel microcontroller crashes from firmware corruption or RTC (real-time clock) battery depletion. Relay coil insulation breakdown traps contacts after repeated genset start cycles, preventing manual override.

Frequently Asked Questions — KOHLER Repairs
Do you repair Kohler genset engines and control systems anywhere in India?+
Yes. Synchronics repairs the complete Kohler product range — generator sets, automatic transfer switches, voltage regulators, governors, and control panels. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, Nashik, and all other major cities. All repairs are handled at our main facility in Vadodara, Gujarat, with typical turnaround of 5-10 business days.
What is typical downtime when a Kohler genset governor or AVR fails?+
Kohler generator governor or AVR failures impact power quality and load acceptance instantly. Synchronics Emergency Service offers 24-hour turnaround for governor solenoid coil replacement and AVR capacitor bank restoration. We also provide on-site preventive maintenance every 6-12 months to Indian factories, replacing worn springs, cleaning fuel injectors, and recalibrating control sensors before failures occur. This reduces unplanned downtime by 80%.
Are Kohler spare parts available in India, and do you stock them?+
Synchronics maintains stock of high-wear Kohler components — AVR capacitors, governor springs, relay coils, fuel injectors, and control board modules — at our Vadodara warehouse. For critical spares like alternator exciter windings or Woodward governor units, we coordinate with authorized Kohler distributors across India to expedite delivery within 3-5 days. We also manufacture drop-in replacements for legacy components no longer available from OEM channels.
Can you synchronize multiple Kohler gensets for parallel operation?+
Yes. Synchronics specializes in synchronizing dual or triple Kohler diesel generator sets for hospitals, data centres, and continuous-process industries across India. We install load-sharing control modules, calibrate governor droop settings, and test phase-matching on utility paralleling panels. Our engineers commission isochronous speed governors and cross-current compensation to balance kVA loading within 5% across all units under dynamic load transients.
What maintenance does a Kohler genset require to prevent premature AVR or governor failure?+
Kohler recommends quarterly fuel system cleaning, annual air filter replacement, and biennial full overhaul for high-duty industrial gensets in India. Synchronics preventive maintenance includes: cleaning fuel injectors, replacing governor damping oil and seals, testing AVR sensing transformer isolation, replacing engine coolant, and calibrating all control module sensors. This extends genset lifespan by 5-10 years and maintains emissions compliance with Indian industrial air quality standards.
How do I send my KOHLER 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 KOHLER 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 KOHLER 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 KOHLER 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.
