DAIKIN Equipment We Repair — By Category
DAIKIN Product Lines We Repair
Our engineers are trained on the full DAIKIN product range. Below are the major product families we service.
Daikin VRV (Variable Refrigerant Volume) Systems
Multi-zone air conditioning systems with inverter-driven compressors managing individual room cooling. Common faults include refrigerant leaks, compressor blade wear, expansion valve blockages, and PCB control failures affecting zone regulation.
Daikin Scroll Compressors
Hermetic compressors used in industrial chilling and cooling applications. Typical issues include oil degradation, scroll element seizure, capacitor burnout, and motor winding faults under continuous duty cycles.
Daikin Air Handling Units (SKY Series)
Modular units for large commercial and industrial ventilation with integrated heat recovery. Common failures include motor bearing wear, filter bypass, damper blade stiction, and control board insulation breakdown.
Daikin Inverter Drive Modules
High-efficiency variable frequency drives for compressor and fan motors. Typical faults include IGBT failures, DC link capacitor degradation, firmware corruption, and thermistor sensing errors in harsh industrial environments.
Daikin Refrigerant Charge Control Systems
Electronic expansion valves and oil management systems ensuring optimal refrigerant distribution. Common issues include stepper motor jamming, solenoid coil burnout, pressure transducer drift, and control algorithm failures.

Common DAIKIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAIKIN equipment arriving at our workshop.
- ✓VRV compressor unable to start or stutters — Daikin VRV systems commonly fail due to failed soft-start capacitors in the inverter module or weak refrigerant superheat preventing compressor rotation. Motor winding resistance drift is also typical after 5-8 years of continuous operation in Indian heat conditions.
- ✓Refrigerant leak from expansion valve or tube connections — Daikin expansion valves and solder joints degrade due to vibration, thermal cycling, and moisture contamination in humid Indian climates. Electrochemical corrosion of copper tubing occurs when system is exposed to salt-air environments or industrial pollutants.
- ✓PCB control board showing err code E4 or E5 communication failure — Daikin indoor and outdoor unit communication fails due to loose signal wiring, corroded connectors, or corrupted firmware on the main PCB. Power supply rail degradation (capacitor drying) prevents stable bus voltage for serial data transmission in the multi-zone VRV network.
- ✓Air handling unit motor running but fan blade not turning or making noise — Daikin SKY series fan bearings seize due to lubricant oxidation and contamination from bypass ductwork. Blade pitch actuator failures prevent variable geometry blade positioning, causing static imbalance and vibration.
- ✓IGBT power semiconductors burned out with burned smell from outdoor unit — Daikin inverter IGBTs fail due to gate drive voltage collapse from failed photocoupler isolation or shorted freewheeling diodes. Thermal runaway occurs when inverter cooling fans clog with dust in Indian industrial environments, reducing heat dissipation.
- ✓Low cooling capacity or compressor running continuously without reaching setpoint — Daikin compressor loses displacement due to scroll element abrasion, piston wear, or leakage past discharge valve rings. Refrigerant charge loss from leaks or TXV under-feeding reduces cooling effect. Oil fouling of heat exchanger surfaces reduces efficiency.

Frequently Asked Questions — DAIKIN Repairs
Do you repair Daikin VRV air conditioning systems anywhere in India?+
Yes. Synchronics is an authorized Daikin repair partner for the complete VRV and SKY product range across India. We offer PAN India express pickup from all major cities including Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Pune, Ahmedabad, and Vadodara. All repairs are conducted at our factory in Vadodara, Gujarat with 24-48 hour turnaround for non-compressor faults.
Can you repair Daikin scroll compressors or do you only handle controls?+
Synchronics repairs the full Daikin product stack. We service Daikin scroll compressors (JT, SH, SM series), motor windings, capacitors, and inverter drives. For severe compressor wear or internal damage, we source OEM Daikin replacement cores and manage on-site compressor changeover if required. All refrigerant handling is certified and EPA-compliant.
What happens if a Daikin VRV unit shows E4 or E5 error code?+
E4 and E5 codes indicate communication failure between indoor and outdoor units in the Daikin multi-zone network. Synchronics first tests signal wiring continuity, checks PCB connector corrosion, and resolders dry joints on the main control board. We reprogram Daikin firmware using OEM diagnostic tools and perform full system commissioning with all zones active. This typically resolves the fault within 24 hours.
How do you handle Daikin refrigerant leaks and system recharge?+
We perform nitrogen pressure decay tests to identify micro-leaks in Daikin tubing, connections, and expansion valves. Once leaks are sealed or faulty components replaced with OEM Daikin parts, the system is evacuated to <3 microns using certified vacuum pumps. Recharge is done to Daikin factory specifications using R410A or R32 refrigerant with moisture analysis. Leak test is re-run post-recharge.
What is your warranty on Daikin repair services?+
All Daikin compressor and motor repairs carry 12 months on parts and labour. Replaced capacitors, PCBs, and electronic modules carry 18 months. Field repairs like pipe brazing and solder rework carry 6 months. Warranty excludes refrigerant loss from system leaks and damage from power surges or customer mishandling. Service records and parts certifications are provided for all warranty claims.
How do I send my DAIKIN 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 DAIKIN 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 DAIKIN 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 DAIKIN 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.
