Common Siemens Failures We Repair

Fault codes we diagnose and resolve at component level — no unnecessary board swaps.

F30001 — Power Module Fault

IGBT failure in SINAMICS G120. Most common failure on high-cycle conveyor and pump applications. Individual IGBT replacement — not a full power module swap.

A07012 / F07011 — Overtemperature

Cooling fan failure on G120/S120 drives. Fan replacement, thermal compound service, and full load test to confirm thermal management is restored.

S7 PLC CPU Module Error

S7-300/400 CPU stops scanning. Battery failure, memory fault, or CPU board failure. Program backup performed before repair — fully restored after.

SIMATIC HMI Touch Failure

KTP/TP panel responds but input is inaccurate, drifting, or dead zones appear. Touch layer replacement without replacing full panel hardware saves significant cost.

Why Flexa for Siemens Repair

Deep technical expertise across the full SINAMICS and SIMATIC product range — not just fault code resets.

Component-Level Repair

We diagnose SINAMICS drives and SIMATIC PLCs at the circuit board level. IGBTs, gate drivers, DSPs, power supplies — root cause identified and fixed.

2-Year Warranty on All Repairs

All Siemens drive and PLC repairs carry a 2-year parts and labor warranty. Full load test and functional verification before every shipment.

Saves 40–70% vs. New

A SINAMICS G120 power module can cost $2,000–$8,000 new. Our repair averages 30–50% of replacement cost — with equal or better reliability post-repair.

Rush Service Available

  • SIMATIC S7 PLC CPU: $500–$1,500

Free evaluation — you receive a firm quote before any work begins.

Can you repair Siemens S7-300 and S7-400 PLCs?

Yes. S7-300 and S7-400 are legacy systems but remain in operation at thousands of facilities. We repair CPU modules, I/O modules, and communication cards. PLC program is always backed up before service and fully restored on return — no reprogramming required.

What Siemens fault codes can you diagnose and fix?

Most common faults we resolve at component level:

  • F30001 — IGBT / power module failure (SINAMICS G120)
  • A07012 / F07011 — Overtemperature, cooling fan failure
  • F07900 — Motor encoder fault
  • SIMATIC CPU STOP — Battery failure, memory fault, CPU board fault
  • SIMATIC HMI touch failure — Touch layer dead zones or drift
Do you repair Siemens SINAMICS S120 multi-axis systems?

Yes. We repair S120 control units (CU320-2), active line modules (ALM), single motor modules, and double motor modules at component level. S120 systems often carry lead times of 16–30 weeks for new units — repair is typically the fastest path back to production.

What warranty do you offer on Siemens repairs?

All Siemens repairs carry a 2-year parts and labor warranty. Every unit is fully load-tested before return shipment. If the same fault recurs within the warranty period, we repair it at no charge.
