What Every Drive Repair Includes
Full component-level teardown on every variable frequency drive — not just a fault code reset
Failed IGBTs and power modules are the leading cause of drive failure. We replace them with OEM-spec components and retest under full load before return.
Damaged control boards, failed power supply circuits, corrupted memory, and communication faults are all diagnosed and resolved at component level — not by board swap.
DC bus capacitors degrade silently over time. Every unit receives capacitance testing with preventive replacement if below OEM spec — stopping the next failure before it starts.
Every VFD drive is tested at rated voltage and current before it ships. Our VFD repair services are backed by a 2-year parts and labor warranty.
