Which VFD brands do you repair?

Siemens SINAMICS, ABB ACS, Delta VFD/MS/MH/CH, Mitsubishi FR, Yaskawa V1000/A1000/GA-series, Danfoss VLT, Fuji FRENIC, Schneider Altivar, LS Electric iS7/iG5A, Inovance, INVT, Veichi — all repaired to component level with warranty per service terms.

What are the most common VFD failure causes?

Voltage spikes and phase imbalance, IGBT thermal stress from cooling-fan failure, aged / dry electrolytic capacitors, blown gate-driver boards, contamination on power boards, and firmware corruption from unstable supply. We diagnose the root cause — not just the symptom.

Do you repair the IGBT power stage or only the control board?

Both. Our engineers replace IGBT modules, rebuild driver stages, reflow damaged tracks and repair control PCBs at component level. Every repair is functionally tested per equipment requirements before dispatch.

How long does a bench VFD repair take?

Typical turnaround is 3–7 working days from arrival, including diagnostics, component-level repair, parameter restoration and testing per equipment requirements. Emergency swap-outs may be possible via our exchange inventory, subject to availability.

Do you supply refurbished VFDs?

Yes — quality-matched refurbished units are available for many popular models with warranty per service terms, ideal when the original OEM has discontinued the part.
