ARPECO Product Lines We Repair
Our engineers are trained on the full ARPECO product range. Below are the major product families we service.
ARPECO Compressor Controllers
Digital and analog controllers managing compressor start-stop cycles, unloader valve operation, and discharge pressure regulation. Common issues include microcontroller burnout, relay contact welding, and capacitor failure causing thermal runaway or erratic compressor cycling.
ARPECO Condensing Unit Control Panels
Integrated control assemblies for air-cooled and evaporative condensing units with fan motor starters, thermostatic regulator boards, and alarm circuits. Failures include fan contactor sticking, overload relay nuisance trips, and temperature sensor open-circuit conditions.
ARPECO Temperature and Pressure Regulators
Electronic thermostatic expansion valve (TXV) drivers and digital thermostats for precise evaporator superheat and cabinet temperature control. Common faults include solenoid winding insulation breakdown, sensor resistance drift, and PWM driver IC failures.
ARPECO Refrigerant Pressure Transducers
4-20mA and 0-10V output sensors monitoring discharge and suction line pressures. Typical repair issues are connector corrosion from humid factory environments, diaphragm rupture from pressure spike, and 0-output failure due to signal conditioning amplifier IC damage.
ARPECO Alarm and Fault Display Modules
LED/LCD indicator panels and audible alarm drivers for high-pressure cutout, low-pressure cutout, motor overload, and temperature alarm states. Failures include display segment burnout, buzzer driver transistor failure, and logic board relay chattering.
ARPECO Power Supply and Transformer Modules
24 VDC and 12 VDC regulated supplies for control circuits with spike protection and thermal shutdown. Common defects are capacitor electrolyte leakage, rectifier diode short-circuit, and voltage regulator IC overheating in high ambient environments.

Common ARPECO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARPECO equipment arriving at our workshop.
- ✓Compressor unloader solenoid coil burnout — ARPECO unloader solenoids experience winding insulation failure due to moisture ingress in humid Indian factory environments combined with sustained voltage ripple from controller rectification circuits. Thermal stress from continuous operation in high-ambient (45°C+) conditions accelerates dielectric breakdown.
- ✓Temperature sensor open-circuit or resistance drift — ARPECO NTC and RTD thermistors develop intermittent open circuits from vibration-induced lead fatigue in condensing units mounted on unbalanced compressors. High humidity causes sensor connector corrosion and millivolt-level resistance shifts masking true cabinet temperature.
- ✓Condensing fan contactor mechanical sticking — ARPECO condensing unit panels in outdoor installations accumulate insect debris and mineral dust inside contactor coil cavities, mechanically binding armature movement. Salt spray corrosion in coastal Indian facilities creates oxide layer preventing contact dropout.
- ✓Microcontroller logic circuit failure or code corruption — ARPECO digital controllers suffer code memory corruption from electrical transients on 230V AC mains common in Indian industrial areas with poor power quality. Voltage spikes couple into microcontroller clock and data lines, corrupting program execution.
- ✓Electrolytic capacitor leakage and power supply voltage sag — ARPECO power supply modules use general-purpose aluminum electrolytic capacitors sensitive to ripple current heating. Continuous operation at 35-45°C ambient in dairy and food processing plants accelerates electrolyte evaporation, increasing internal impedance and causing 12/24 VDC rail sag during transient loads.
- ✓Pressure transducer 4-20mA output saturation or zero reading — ARPECO transducers fail when mounting connectors corrode in humid ammonia or CO2 refrigerant environments common in Indian dairy plants. Internal silicon pressure sensor diaphragms rupture from hydrostatic shock when high-side solenoid opens suddenly, venting discharge pressure.

Frequently Asked Questions — ARPECO Repairs
Do you repair ARPECO equipment anywhere in India?+
Yes. Synchronics repairs the complete ARPECO refrigeration electronics range — compressor controllers, TXV drivers, pressure transducers, condensing unit panels, and alarm modules. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Ahmedabad, Chennai, Hyderabad, and all major cities, with central repair facility in Vadodara, Gujarat. Typical turnaround is 3-5 working days including component replacement.
What is the typical turnaround for ARPECO compressor controller repair?+
ARPECO compressor controllers are diagnosed within 24 hours of receipt at our Vadodara facility. Simple repairs like relay replacement or capacitor swap take 1-2 days. Complex microcontroller reprogramming or full circuit board rework (solenoid coil replacement, transformer testing) requires 3-4 days. We provide daily status updates via WhatsApp and expedited return shipping on request.
Can you repair ARPECO units that have ammonia refrigerant exposure?+
Yes. Synchronics has specialized cleaning and testing protocols for ARPECO electronics exposed to ammonia and CO2 refrigerants common in Indian food processing plants. We ultrasonically clean all circuit boards in IPA to remove ammonia residue, test component insulation resistance, and replace any corroded connectors or sensor ports. All repaired units receive stainless steel hardware and protective silicone potting on sensitive circuits.
Do ARPECO thermistor sensors need calibration after repair?+
ARPECO NTC and RTD thermistors are precision components — after replacement, we verify new sensors against ARPECO calibration standards using a temperature chamber (-10°C to +60°C range) to ensure ±0.5°C accuracy before shipment. We provide a calibration certificate for compliance records. No reprrogramming of your controller is needed if replacement sensors match original resistance values.
What warranty do you offer on ARPECO refrigeration control repairs?+
All ARPECO repairs carry a 12-month warranty on parts and workmanship for same fault recurrence. For compressor controllers and TXV drivers, warranty extends to 18 months if customer agrees to UPS-backed mains conditioning (recommended for Indian industrial sites). Labor warranty is unconditional; spare parts warranty covers manufacturing defects. We stock genuine ARPECO replacement components at our Vadodara facility.
How do I send my ARPECO 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 ARPECO 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 ARPECO 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 ARPECO 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.
