"Just by first impressions, it seems as though Repair Zone knows what you're doing. My company is based out of Knoxville, Tennessee. But regardless of my location versus yours, I'm sure you will be hearing a lot more from me. Thank you for your assistance. Have a great weekend."

Fanuc Servo Amplifier Repair


Fanuc servo amplifier repair is our fast service that gets your machine running.



Repair Zone can repair all Alpha, Alpha i, Beta, and C series amplifiers from Fanuc. When we receive your Fanuc servo or spindle amplifier unit:

  • We do a thorough inspection including run-testing to verify any faults before we start any repairs.
  • We then clean & bake the unit to assure all contaminates are removed
  • We perform comprehensive component testing then replace any diodes, resistors, IGBT’s, or other damaged components that we have identified as an issue, along with preventative replacement of components that we have seen as a common failure on amplifiers like electrolytic capacitors and fans
  • We perform as many static tests as we can on each of the individual circuits as part of our repair process.
  • Finally, we test-run your unit again for a minimum of 2 hours before shipping it back to you.

Repair Zone, your servo motor and Fanuc amplifier repair experts.
