SHIHLIN Equipment We Repair — By Category
SHIHLIN Product Lines We Repair
Our engineers are trained on the full SHIHLIN product range. Below are the major product families we service.
Shihlin Frequency Inverters (AC Drives)
Variable frequency drives (VFDs) for 3-phase AC motors ranging 0.75 kW to 355 kW. Common failures include IGBT module burnout, capacitor degradation, and control board short circuits. Shihlin inverters are heavily used in pump, fan, and conveyor applications.
Shihlin Soft Starters
Electronic motor soft-starters for reducing inrush current and mechanical stress on motors and driven equipment. Typical issues include thyristor gate-drive failures, current sensor faults, and overheating of internal heatsinks due to inadequate ventilation.
Shihlin Programmable Logic Controllers (PLCs)
Compact and modular PLCs for manufacturing process control and machine automation. Repair challenges involve input/output module failures, memory corruption, communication port damage, and relay contact wear in digital output cards.
Shihlin Power Distribution & Protection Modules
Motor protection relays, overload devices, and DIN-rail mounted control terminals. Common defects include thermal element aging, contact erosion leading to nuisance trips, and connector oxidation in humid factory environments.
Shihlin Temperature & Process Controllers
Microprocessor-based controllers for temperature, pressure, and flow monitoring in industrial processes. Failure modes include sensor input calibration drift, output relay chattering, and display LCD panel degradation over prolonged use.

Common SHIHLIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SHIHLIN equipment arriving at our workshop.
- ✓Shihlin VFD IGBT module thermal runaway failure — IGBT gate-drive transformer saturation or capacitor aging causes reduced gate voltage, leading to excessive heat dissipation and junction breakdown in the power stage. This is especially common in Shihlin SVF-LS inverters operating in humid, high-ambient-temperature Indian factory environments.
- ✓Shihlin soft starter thyristor gate-drive circuit open — The opto-coupler isolating the control signal from the power thyristor fails due to solder joint cracking or internal chip degradation. Vibration from nearby machinery and thermal cycling accelerate opto-coupler aging in Shihlin ST2 series starters.
- ✓Shihlin PLC input/output module address conflict or no-response error — Connector corrosion, loose module seating, or firmware incompatibility after partial updates causes I/O communication dropouts. This is frequent in textile mills and chemical plants with corrosive vapor or dust ingress into PLC enclosures.
- ✓Shihlin motor protection relay spurious trip or calibration drift — Thermal element aging, capacitor C0 coefficient change, or trimpot contamination causes the relay overload threshold to drift 5-15% from nominal setting. Cement and sugar plants experience rapid thermal aging due to high ambient temperatures and dust ingress.
- ✓Shihlin frequency inverter capacitor bank bulging or leakage current rise — Electrolytic capacitor aging is accelerated by continuous full-load operation, high ambient temperature (>45°C), and ripple current stress in SVF-LS drive topologies. Capacitor ESR increases, reducing bus voltage stability and causing nuisance fault codes E07 or E08.
- ✓Shihlin PLC display panel LCD pixels dead or liquid crystal discoloration — Excessive ambient heat, prolonged UV exposure, or manufacturing defect in the LCD backlight circuit reduces contrast and readability. Common in outdoor control panels or enclosures near furnaces in Indian steel and ceramic industries.

Can Synchronics repair Shihlin soft starters with thyristor failure?+
Yes. We specialize in Shihlin ST2 series soft starter power stage repair. Our facility stocks matched pairs of high-current thyristors and performs precision gate-drive circuit reconstruction. We test the repaired starter on a 3-phase motor load bank before dispatch. Typical repair cost is 40-60% of a new unit replacement, with 2-year warranty.
Do you offer Shihlin PLC module replacement or refurbishment?+
Yes. Synchronics repairs and refurbishes Shihlin PMC series PLC CPU modules, I/O cards, power supplies, and communication modules. We use EEPROM programming and JTAG-based fault diagnosis to identify and repair defective components. If a module is unrepairable, we source compatible OEM or approved alternative modules and perform firmware synchronization.
What warranty does Synchronics provide on Shihlin equipment repairs?+
Synchronics provides a 24-month warranty on all Shihlin equipment repairs covering parts and labor. For units requiring capacitor or IGBT replacement, we extend warranty to 36 months. We maintain detailed repair logs with photographs and functional test reports for every unit, available to customers for compliance and future maintenance planning.
How do I send my SHIHLIN unit for repair?+

What is the cost of repairing a SHIHLIN 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 SHIHLIN 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 SHIHLIN 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.
