Allen-Bradley VFD Repair Service

Flexa Systems repairs Allen-Bradley VFD PowerFlex 400 series drives at component level. The most common failure modes — IGBT module failure (F005 ground fault, overcurrent trip), gate driver board faults, and DC bus capacitor degradation — are all diagnosed and repaired at the circuit board level, not by board swap. Component-level repair on PowerFlex 40/40P/525 typically saves $400–$800 compared to purchasing a new drive, and is often the fastest solution when OEM replacement lead times are 6–16 weeks.
