FARM FANS Product Lines We Repair
Our engineers are trained on the full FARM FANS product range. Below are the major product families we service.
Thermostat Controllers and Environmental Control Units
Farm Fans thermostatic controllers manage temperature and humidity in poultry houses and livestock facilities using sensor feedback and relay logic. Common failures include stuck relays, sensor communication faults, thermal cutoff activation, and erratic temperature cycling due to calibration drift or water ingress.
Variable Speed Drive Systems
VFD-based fan speed controllers from Farm Fans modulate ventilation airflow in response to building temperature and moisture levels. Typical repair issues involve power stage failures, PWM signal loss, fan motor non-response, phase loss during supply, and triac/contactor burnout in older DC speed control boards.
Humidity and Temperature Sensor Assemblies
Farm Fans sensor modules measure ambient conditions inside poultry and livestock facilities to trigger ventilation adjustments. Frequent faults include capacitive sensor degradation, signal conditioning circuit failure, corroded connectors causing intermittent readings, and non-linear output curves requiring recalibration.
Intake Shutter and Damper Controllers
Electronic actuator controllers from Farm Fans regulate inlet dampers and ceiling shutters to direct incoming air and maintain facility pressure balance. Common failures include solenoid coil burnout, PWM driver failure, position feedback sensor malfunction, and mechanical binding causing overcurrent shutdown.
Backup Power and Alarm Monitoring Systems
Farm Fans emergency control boards interface with backup power supplies and alarm horns to protect livestock during ventilation failures. Typical issues are battery charging circuit faults, alarm relay sticking, loss of 24V control power, and sensor input processing circuit failures causing nuisance alarms.

Common FARM FANS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FARM FANS equipment arriving at our workshop.
- ✓Farm Fans thermostat fails to cycle ventilation fans — Relay contacts corroded or stuck due to humidity and dust ingress common in poultry facilities. Temperature sensor disconnection or open-circuit wiring harness prevents controller from receiving building temperature feedback.
- ✓Farm Fans VFD produces no fan motor output signal — Power stage MOSFET or IGBT failure, internal fault in gate driver circuit, or loss of 480V three-phase supply to drive input terminals. PWM modulation signal from control processor may be absent or distorted due to microcontroller reset.
- ✓Humidity sensor reading drifts or becomes non-responsive — Capacitive humidity sensing element contaminated by ammonia vapor, dust, and moisture condensation in harsh poultry house environments. Signal conditioning amplifier offset voltage increases, or sensor bridge excitation supply fails.
- ✓Farm Fans intake damper solenoid remains in fail-safe position — Solenoid coil winding open or shorted due to voltage spikes during harsh weather or moisture intrusion into solenoid valve body. Solenoid driver transistor in control board fails, or 24VDC solenoid supply is absent due to fuse failure.
- ✓Farm Fans backup power module fails to energize alarm circuits — Battery charging circuit malfunction prevents rechargeable backup battery from holding charge due to shorted charging diode or failed voltage regulator. Alarm relay coil burned or contacts welded closed by electrical arc during brief power interruption.
- ✓Farm Fans controller generates spurious temperature alarms continuously — Temperature sensor wiring harness partially disconnected or corroded connectors causing intermittent open-circuit sensor input. Analog-to-digital converter input offset in microcontroller firmware causes misinterpretation of sensor voltage as over-temperature or under-temperature condition.

Frequently Asked Questions — FARM FANS Repairs
Do you repair Farm Fans equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Farm Fans product range — environmental control units, VFD drives, sensor modules, damper controllers, and backup power systems. We offer PAN India door-to-door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all industrial towns. All repairs are completed in our Vadodara, Gujarat facility and returned to your location within 5-7 working days.
What is the typical repair time for Farm Fans thermostat controllers in poultry facilities?+
Farm Fans thermostat controller repair typically takes 3-5 days depending on component availability and complexity. Synchronics diagnoses the issue within 24 hours of receipt using automated test equipment. If relay contacts or sensor assemblies require replacement, these components are usually in stock. We perform full temperature cycling testing and sensor calibration before return to ensure your controller maintains accurate climate control in your poultry operation.
Can Synchronics repair Farm Fans VFD drives for large-scale poultry houses?+
Yes. Synchronics specializes in Farm Fans VFD repair for multi-stage poultry facilities with 50kW to 200kW ventilation fan motor systems. We perform power stage repair, gate driver replacement, PWM signal reconstruction, and firmware re-programming. Our engineers test repaired drives under load with actual Farm Fans fans installed in our test facility to verify smooth speed modulation and thermal stability before shipment back to your farm.
My Farm Fans humidity sensor readings are unstable. Can this be repaired or must I buy a new sensor?+
Unstable humidity readings from Farm Fans sensors are usually repairable. The capacitive sensing element often requires cleaning to remove ammonia vapor and dust contamination common in poultry houses. Synchronics carefully cleans the sensor element and re-calibrates the signal conditioning circuit using a precision humidity test chamber. Cost of repair is typically 40-50 percent of a new sensor. If the capacitive element is physically damaged, we replace it and recalibrate the entire assembly to Farm Fans factory specifications.
How do I know if my Farm Fans controller requires repair versus simple maintenance?+
If your Farm Fans environmental controller cycles fans erratically, fails to turn fans on or off at set temperatures, or displays locked-in alarm status, professional repair is needed. Synchronics can diagnose whether the issue is dirty relay contacts (maintenance), failed electronics (repair), or a misaligned temperature sensor (sensor replacement). We recommend periodic inspection every 12-18 months in high-dust poultry environments. Contact Synchronics with your controller model and fault symptoms — our engineers will advise whether repair or replacement is most economical.
How do I send my FARM FANS 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 FARM FANS 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 FARM FANS 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 FARM FANS 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.
