FOTEK Equipment We Repair — By Category
FOTEK Product Lines We Repair
Our engineers are trained on the full FOTEK product range. Below are the major product families we service.
FOTEK Temperature Controllers
FOTEK's range of digital and analog temperature controllers including MT series and MT72 models used for process heating control. Common issues include sensor input failures, relay output faults, calibration drift, and firmware corruption affecting PID loop stability.
FOTEK Solid State Relays (SSR)
Industrial-grade SSRs for switching AC/DC loads without mechanical contacts. FOTEK SSR units are common in Indian textile looms, plastic extrusion, and heat treatment furnaces. Typical failures include gate drive circuit burnout, thyristor shorts, and isolation breakdown under thermal stress.
FOTEK Digital Timers & Counters
Multi-function digital timers (relay output, transistor output, SSR compatible) and counters for industrial counting, timing, and sequencing. Issues include display segment failure, counting pulse input dropout, relay contact welding, and time-base oscillator drift.
FOTEK Level Controllers & Sensors
Float-based and capacitive level control units for pump and solenoid valve automation in water treatment, chemical dosing, and tank management applications. Failures involve float mechanism sticking, sensor signal noise, relay contact oxidation, and hysteresis adjustment loss.
FOTEK Pressure & Process Transmitters
Analog and digital pressure transmitters with 4-20mA output for process monitoring in compressor plants and hydraulic systems. Common faults include transducer diaphragm fatigue, amplifier IC failure, linearization error, and connector corrosion.
FOTEK Panel Meters & Displays
Digital panel meters, multimeters, and display units for monitoring voltage, current, frequency, and power factor in Indian manufacturing switchboards. Typical issues include LCD segment failure, input terminal burnout from overvoltage transients, and calibration offset.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common FOTEK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FOTEK equipment arriving at our workshop.
- ✓FOTEK Temperature Controller - No Display Output — LCD display degradation due to age or power surge, or microcontroller watchdog reset from EMI interference. Common in textile mill environments with high electromagnetic noise from induction motors.
- ✓FOTEK SSR - Continuous Output or Load Not Switching — Gate drive optocoupler failure or thyristor gate oxide rupture from overvoltage transient. Mechanical contactor-based load switching can send reverse EMF spikes damaging FOTEK SSR gate circuits.
- ✓FOTEK Timer/Counter - Erratic Counting or No Pulse Recognition — Input conditioner circuit failure, debounce capacitor drying, or signal isolation transformer primary winding short from moisture ingress. Common in high-humidity pharmaceutical and food processing plants.
- ✓FOTEK Level Controller - Relay Sticks or Chatters Continuously — Relay contact material erosion or welding from arcing under capacitive load switching. Float mechanism sticking in intermediate position due to mineral deposits in water.
- ✓FOTEK Temperature Sensor Input Shows -199 or ERR Code — Thermocouple or RTD sensor open-circuit, corroded connector pin contact, or broken sensor wire in conduit. Input amplifier IC failure can also generate error codes without sensor disconnection.
- ✓FOTEK Digital Display - Segment Flicker or Intermittent Decimal Points — LCD display multiplexing frequency drift from aging crystal oscillator, or intermittent microcontroller clock line contact from vibration in rotating machinery environments.

Frequently Asked Questions — FOTEK Repairs
Do you repair FOTEK equipment anywhere in India?+
Yes. Synchronics repairs the full FOTEK product range - temperature controllers, SSRs, timers, counters, level controllers, and process transmitters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other metro and tier-2 cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat with turnaround time of 3-5 working days.
How do you repair FOTEK temperature controllers with sensor disconnection errors?+
Our engineers first isolate the sensor input amplifier stage from the microcontroller using precision signal generators. We test amplifier gain, offset voltage, and linearity across the full input range. Then we verify the sensor connector pin contact resistance and measure break-detection threshold settings. If the error persists, we reprogram FOTEK's firmware calibration tables from archived service images. All repairs include thermal cycling to verify stability.
What warranty do you provide on FOTEK SSR repairs?+
Synchronics provides 12 months warranty on all FOTEK SSR repairs including optocoupler replacement, thyristor module renewal, and snubber circuit restoration. Within the warranty period, if the same fault recurs, we repair free of charge plus shipping both ways. We recommend replacing aging heat sinks and adding output RC filters to protect repaired FOTEK SSRs from utility surge transients.
Can you recalibrate FOTEK temperature controllers to match industry standards?+
Yes. Synchronics recalibrates all FOTEK temperature controllers against Fluke and Yokogawa reference standards traceable to NIST. We adjust PID loop tuning parameters, linearization curves, and sensor input scaling. Calibration certificates are provided for validation units if required by your ISO 9001 or pharmaceutical QMS audits. Recalibration cost is included in standard repair charges.
How do I prevent EMI-induced faults in my FOTEK instruments?+
Synchronics recommends: (1) Use twisted, shielded sensor cabling grounded at both PLC and instrument ends, (2) Install ferrite clamp filters on all signal leads entering FOTEK controllers, (3) Mount instruments away from VFD and contactor banks by at least 1.5 meters, (4) Use 24VDC isolated power supplies with transient suppression capacitors, (5) Add RC snubber networks across relay contact points. These steps prevent 80% of FOTEK faults we observe in Indian textile and steel mills.
How do I send my FOTEK 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 FOTEK 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 FOTEK 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 FOTEK 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.
