Bitmain Warranty

Bitmain supply their customers with a 1 year warranty, however, that warranty comes with limitations. For example, the warranty won’t be valid if you overclock the miner (running it at a higher speed than it was designed to run). Also, if you use an inappropriate power supply or generate environmental damage to your miner you won’t be eligible for a warranty (e.g. lightning strike, corrosion due to the wet environment).

The following events will void the warranty:

  • Customer removes/replaces any components by himself without receiving written permission from manufacturer
  • Damage caused by poor power supply, lightning or voltage surges
  • Burnt parts on hash boards or chips
  • Boards/components damage due to water immersion or corrosion due to wet environment
  • Bitmain’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via hardware and/or software.

If one of the cases above happens, you shall not be able to claim the warranty. For any specific procedures, please refer to the after-sales process.

Please don’t send any machine or parts without contacting the technical support team first. Any loss or damage as a result of lack of contact will be the responsibility of the customer.

For all repairs, within warranty or not, customer must return the defective parts at their own expense after opening a support ticket and troubleshooting with Bitmain’s instructions.
