FURNAS Product Lines We Repair
Our engineers are trained on the full FURNAS product range. Below are the major product families we service.
Magnetic Motor Starters (NEMA / IEC)
Heavy-duty electromagnetic starters for AC induction motors up to 600V. Common issues include coil burnout, contact arcing, mechanical jamming of armature, and chattering due to low voltage conditions.
Soft Starters (Solid-State)
Programmable soft-start controllers for smooth motor acceleration and reduced inrush current. Typical faults include thyristor failures, firing circuit failures, temperature sensor drift, and internal power supply collapse.
Overload Relays and Thermal Protection
Electromechanical and electronic overload protection devices. Common failures: bimetallic strip fatigue, temperature compensation drift, reset mechanism sticking, and false trip sensitivity loss.
Control Transformers and Coils
Step-down transformers and replacement coils for Furnas starters and contactors. Repair issues include primary/secondary winding insulation breakdown, lamination corrosion, and coil desaturation.
Push Button Stations and Selector Switches
Industrial-grade operator interface components with maintained and momentary contacts. Common faults: contact oxidation, mechanical binding of plunger, spring fatigue, and housing water ingress.
Disconnect Switches and Safety Switches
Manual and safety-rated disconnecting means for motor and feeder circuits up to 600V. Typical issues: main blade wear, spring tension loss, arc chute pitting, and solenoid interlock failure.

Common FURNAS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FURNAS equipment arriving at our workshop.
- ✓Magnetic coil burnout and winding open circuit — Furnas starters operate on sustained AC voltage. Coil failure occurs from prolonged overvoltage (+/- 10% supply variance), contamination-caused insulation breakdown, or mechanical coil jamming. Common in mills and heavy process plants with unstable power supply.
- ✓Contact erosion and arc pitting on main and auxiliary contacts — Repeated switching of inductive loads (motors, solenoids) causes arcing and material transfer. Furnas contactors rated for general-purpose duty degrade faster under high-frequency switching or inductive surges. Visible as pitting, blackening, or surface cratering on silver alloy contacts.
- ✓Armature mechanical binding and chattering — Furnas starter armatures are suspended by springs and move freely in an air gap. Binding occurs from rust, lamination burrs, paint accumulation, or misalignment. Chattering—rapid opening/closing vibration—indicates low supply voltage, weak springs, or pole face debris.
- ✓Thermal overload relay false trips and sensitivity drift — Furnas bimetallic thermal relays drift in sensitivity over years due to metal fatigue, temperature coefficient aging, or cumulative cycling. Dirt ingress or moisture can affect response. Setting screws loosen causing unpredictable trip points. Common in humid Indian textile and food processing plants.
- ✓Control transformer coil insulation failure and short-to-frame — Furnas control transformers step 480V or 240V to 120V for starter coils and controls. Insulation breakdown occurs from age (30+ years in many plants), moisture (condensation in non-sealed designs), thermal cycling, or vibration-induced winding movement. Results in primary-to-secondary or secondary-to-ground faults.
- ✓Push button and selector switch contact stiction and mechanical jamming — Furnas operator stations are exposed to dust, oil mist, and moisture on factory floors. Contact lubricant dries, and oxidation layer prevents full closure. Mechanical springs and return mechanisms weaken or corrode, trapping the plunger in mid-stroke. More prevalent in printing, packaging, and chemical plants.

Frequently Asked Questions — FURNAS Repairs
Do you repair Furnas equipment anywhere in India?+
Yes. Synchronics repairs the complete Furnas product range — magnetic starters, soft starters, overload relays, control transformers, push button stations, and disconnects. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other industrial cities. Same-day courier to our Vadodara, Gujarat facility. Most repairs turnaround in 3-5 working days.
What is the difference between repairing a Furnas starter versus replacing it?+
Furnas starters are built to last 30-40 years with proper maintenance. Repair is cost-effective for coil burnout, contact erosion, and overload relay drift — typically 40-60% of new unit cost. However, if armature laminations are severely damaged, frame is cracked, or the model is obsolete, replacement may be warranted. Synchronics evaluates your equipment and recommends repair or replacement based on condition and availability.
How do I know if my Furnas magnetic starter coil is failing?+
Signs include: starter fails to pick up (no magnc hum) even with correct voltage applied, coil becomes hot to touch within seconds, starter chatters or vibrates constantly, or you smell a burnt smell from the coil area. You can check coil resistance with a multimeter — typical coil resistance ranges from 500 ohms to 2000 ohms depending on voltage. Open circuit (infinite resistance) indicates coil failure. Contact Synchronics for urgent coil replacement.
Can Furnas starters be repaired on-site or must they be shipped to Vadodara?+
Most Furnas repairs require bench diagnostics and tooling unavailable on-site, so shipment to Synchronics is standard. However, for urgent situations, our field engineers in major Indian cities (Pune, Mumbai, Ahmedabad) can perform limited on-site diagnostics and coil testing. We offer same-day or next-day courier pickup from your facility and guarantee return shipment within 5 days for standard repairs. Call 1-800-SYNC-FIX for emergency support.
What warranty do you provide on Furnas starter and relay repairs?+
Synchronics offers a 12-month manufacturer-equivalent warranty on all repaired Furnas equipment — covering coils, contacts, relays, and mechanical components. Warranty covers defects in repair workmanship and parts sourced by Synchronics. Damage from misuse, incorrect installation, or supply voltage fluctuations outside +/- 10% is excluded. We provide detailed repair reports and testing documentation for your plant records.
How do I send my FURNAS 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 FURNAS 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 FURNAS 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 FURNAS 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.
