Frequently Asked Questions

Q: How do I know if the PCB part number is compatible with my machine?

A: We recommend checking the A16B/A20B number on your existing board. If you're unsure, send us a photo of the label, and our engineers will verify the version.

Q: Are refurbished boards reliable?

A: Yes. Our refurbished boards are cleaned, repaired with high-quality components, and undergo full diagnostic load testing. They often last as long as new units at a fraction of the cost.

Q: What is the warranty on these Fanuc boards?

A: We offer a 12-month warranty for New Surplus items and a 6-month warranty for Refurbished units.

Q: What should I do if the machine shows a "System Alarm" after installation?

A: Most alarms are due to incorrect parameter settings or unseated memory modules. Contact our technical support for a step-by-step troubleshooting guide.

Q: Do these boards include the memory (SRAM/FROM) modules?

A: Usually, mainboards are sold without memory modules unless specified. You can easily swap your old modules onto the new board.
