COOPER Equipment We Repair — By Category
COOPER Product Lines We Repair
Our engineers are trained on the full COOPER product range. Below are the major product families we service.
Cooper Motor Starters & Contactors
Full-voltage and reduced-voltage motor starters with thermal overload protection. Common issues include coil burnout, contact erosion, and overload relay calibration drift affecting motor protection.
Cooper Circuit Protection & Breakers
Industrial circuit breakers and motor protection relays for switchgear applications. Failures typically involve trip coil malfunction, arc chamber erosion, and mechanical latch wear.
Cooper Overload Relays & Thermal Units
Bimetallic and electronic overload protection devices for motor circuits. Common faults include bimetallic strip fatigue, calibration loss, and tripping circuit degradation.
Cooper Reversing & Drum Switches
Manual and electrically-operated reversing starters and selector switches for bidirectional motor control. Failure modes include contact welding, selector mechanism wear, and electromagnetic coil degradation.
Cooper Reduced Voltage Starters
Autotransformer and solid-state soft starters for reduced inrush current on large motors. Issues include transformer core saturation, power device failure, and soft starter control card malfunction.

Common COOPER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COOPER equipment arriving at our workshop.
- ✓Motor starter coil burnout and open circuit — Cooper motor starter coils fail due to voltage surge spikes, phase loss conditions, or sustained overvoltage from utility fluctuations common in Indian industrial areas. Coil winding insulation degrades under thermal stress in harsh environments.
- ✓Contact erosion and chattering in contactors — Cooper contactor contacts erode due to repeated make/break arcing, especially in high-inrush applications like pump motors and compressors. Erosion causes mechanical vibration (chatter) and reduced contact pressure, leading to voltage drop and eventual contact failure.
- ✓Overload relay tripping fault and calibration drift — Cooper bimetallic overload relays lose calibration after 5-8 years of thermal cycling, especially in fluctuating Indian ambient temperatures (30-50°C). Calibration drift causes nuisance tripping or failure to protect motors during genuine overload, risking motor winding damage.
- ✓Thermal unit heater element failure — Cooper thermal units use exposed heater elements that oxidize and fail when exposed to moisture, aggressive plant air (chemical fumes, salt spray in coastal refineries), or vibration. Open-circuit thermal elements provide zero motor protection.
- ✓Mechanical latch and trip mechanism wear — Cooper motor starters subjected to thousands of start cycles develop mechanical wear in the latch mechanism, trip arm pivot pins, and mechanical reset linkages. Worn latches cause incomplete contact opening and delayed trip action, especially during fault conditions.
- ✓Soft starter power module failure and gating circuit malfunction — Cooper reduced-voltage soft starters experience IGBT or thyristor module failure due to heat dissipation inadequacy in high ambient environments, moisture ingress in humid coastal plants, or transient voltage spikes on utility power. Gating circuit failures prevent proper power device commutation.

Frequently Asked Questions — COOPER Repairs
Do you repair Cooper equipment anywhere in India?+
Yes. Synchronics repairs the complete Cooper product range — motor starters, contactors, overload relays, circuit breakers, soft starters, and drum switches. We offer PAN India door pickup from Mumbai, Pune, Delhi, Bangalore, Hyderabad, Ahmedabad, Nagpur, Chennai, Kolkata, and all other major cities. All repairs are completed in our 20,000 sq ft facility in Vadodara, Gujarat.
What is the typical turnaround time for Cooper motor starter repair?+
Standard Cooper motor starter repair takes 5-7 working days including diagnostics, coil rewinding or replacement, contact refurbishment, and full factory test. Urgent repairs can be completed in 48-72 hours. All work is backed by our 12-month repair warranty — if the starter fails due to our repair, we replace it free of charge.
Can you recalibrate Cooper overload relays to match my motor nameplate current?+
Absolutely. Our thermal calibration lab uses certified heating ovens, precision ammeter equipment, and insulated test stands to recalibrate Cooper overload relays to your exact motor specifications. We provide calibration certificates showing trip point accuracy and thermal time constant. This is essential for mills and plants running motors in wide temperature swings across seasons.
What happens if I use a non-Cooper replacement contactor instead of repairing the original?+
Mixing brands voids safety certifications and creates hazardous mismatches in mechanical dimensions, coil voltage/frequency, and contact pressure. Synchronics repairs Cooper with genuine Cooper components — we maintain your original equipment's safety integrity and preserve OEM design margins critical in heavy motor applications like punch presses, cranes, and compressors.
Do you repair Cooper soft starters and reduced-voltage starter power modules?+
Yes. Synchronics specializes in Cooper soft starter repair including IGBT/thyristor power module replacement, control PCB rework, and firmware updates. We repair both autotransformer-based RVSS starters and solid-state soft start units. We test soft starter ramp time, current limiting, and bypass contactor logic to ensure safe motor acceleration on your production lines.
How do I send my COOPER 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 COOPER 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 COOPER 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 COOPER 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.
