When a Variable Frequency Drive (VFD) fails, many plant managers immediately order a replacement. But in most cases, repair is the smarter — and far cheaper — option.
The Cost Reality — A new industrial-grade VFD from ABB, Siemens, or Danfoss can cost ₹50,000 to ₹5,00,000 depending on kW rating. A professional repair typically costs 15–30% of that — saving your facility lakhs of rupees per incident.
What Can Be Repaired? — The vast majority of VFD failures are caused by specific component failures: IGBT modules, capacitors, gate drivers, control boards, and power supplies. These are all repairable at component level.
Common VFD Faults We Fix — Overcurrent trips, DC bus overvoltage, IGBT failure, fan failure, keypad/display faults, communication errors, and earth fault alarms.
When Replacement Makes Sense — If the drive is more than 15 years old, if spare parts are unavailable, or if the repair cost exceeds 50% of replacement cost — then replacement may be justified. We'll always give you an honest assessment.
Lead Time Advantage — A replacement VFD can take 4–12 weeks to arrive from overseas. Our typical repair turnaround is 2–5 working days. For critical production equipment, that difference is enormous.
The Verdict — For any VFD under 12 years old with a known fault, repair almost always wins on cost and speed. Contact Zain Asia Technical Services for a free assessment of your faulty drive.
