How much does VFD repair cost?

VFD repair typically costs 30–60% of the new unit price, depending on the brand, HP rating, and extent of damage. A free diagnostic evaluation is included with no obligation before any repair begins.

How long does VFD repair take?

Standard VFD repair turnaround at Flexa Systems is 5–30 days. Rush service with 24–72 hour turnaround is available for critical production equipment.

What warranty do you offer on VFD repairs?

Every VFD repair at Flexa Systems is backed by a 2-year parts and labor warranty — longer than most OEM replacement warranties.

Where can I get VFD repair in the Dallas or DFW area?

Flexa Systems is located in Lewisville, TX — in the Dallas-Fort Worth (DFW) metro area, approximately 25 miles from downtown Dallas. DFW-area customers can drop off equipment in person by appointment. We also accept mail-in repairs from anywhere in the US.

Can you repair high-voltage VFDs used in industrial and packaging machinery?

Yes. Flexa Systems performs component-level repair on high-voltage industrial drives including medium-voltage VFDs used in pumps, fans, compressors, packaging lines, food processing equipment, and heavy manufacturing. All brands and HP ratings accepted.

How does fast VFD repair minimize production downtime?

Our free same-day diagnostic evaluation and optional 24–72 hour rush service means your production line can be back up faster than waiting for a new unit to arrive. Component-level repair avoids the 2–8 week lead times common for replacement drives, and costs 40–70% less.

What Every Drive Repair Includes

Full component-level teardown on every variable frequency drive — not just a fault code reset

IGBT & Power Module Replacement

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.

Control Board, Power Supply & Firmware

Damaged control boards, failed power supply circuits, corrupted memory, and communication faults are all diagnosed and resolved at component level — not by board swap.

Capacitor & DC Bus Inspection

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.

Full Load Test Before Return

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.
