What should you pay attention to when using repair service?
Here is a more detailed description of the most important aspects to consider when using ASIC miner repair services so that you, as a miner operator, do not take unnecessary risks:
1. Certified partners (e.g. Bitmain, Whatsminer)
A certified repair center is either directly authorized by the manufacturer (e.g. Bitmain , MicroBT/Whatsminer , Canaan ) or works closely with them.
Benefits of certified partners:
- True-to-original repair procedures according to manufacturer specifications
- Access to special diagnostic software and technical data sheets
- In many cases the manufacturer's warranty remains valid
- Higher success rate for complex repairs
- Clear reversal of irreparable devices
Tip: Look for logos like Bitmain Certified Repair Center or Whatsminer Official Partner on the service provider’s website.
2. Original spare parts & professional technicians
A reliable repair service uses only original spare parts and ASIC miner accessories or high-quality OEM components to ensure the longevity and efficiency of your miner.
Important:
- Technicians should have experience with specific models (e.g. Antminer S19j Pro, Whatsminer M30S++)
- Qualifications such as soldering technology (microsoldering) , ASIC rework and thermal diagnostics are crucial
- Repairs such as ASIC replacement or board reflow may only be carried out by trained personnel
3. Fast turnaround time & transparent communication
Especially on large farms , time is money . A good repair service offers:
- Clear time specifications for diagnosis and repair (e.g. 3–5 working days diagnosis time)
- Transparent status updates via email or tracking system
- Possibility to receive cost estimates in advance
- No hiding of additional costs for spare parts or shipping
- Online support for questions or escalations
Tip: Prefer providers with clear SLAs (Service Level Agreements).
4. No impairment of the guarantee
One of the most important questions is: Will the repair void my manufacturer's warranty?
This depends on whether the service provider performs manufacturer-authorized repairs .
Pay attention to:
- Official Bitmain or Whatsminer warranty terms
- Whether the Repair Center reports repair data back to the manufacturer
- Avoid third-party repairs while the warranty is still valid
Best practice: If your device is still under warranty, always send it to an official partner or directly to the manufacturer to avoid voiding the warranty.
What types of repair centers are there?
- Manufacturing centers: Bitmain, Whatsminer, Goldshell
- Certified third-party providers: D-Central (Canada), ZeusBTC (China), EuroTech (DE)
Sending your miner in for repair – here's how
- Collect error log and device data
- Fill out the Repair Center's online diagnostic form
- Prepare for shipping (original packaging, antistatic film)
- Save tracking number
- Waiting for diagnostic report
- Authorize repair

Conclusion: Repair or buy new? – The choice is yours
A professional ASIC miner repair service can significantly extend the lifespan of your mining hardware – especially if you use certified partners, genuine parts, and transparent processes. For mining farm operators or individual miners, a trip to a repair center is almost always worthwhile – whether for error diagnosis, hashboard repair, or cleaning after immersion cooling.
However, sometimes repairs are no longer cost-effective , or technological advances make older models obsolete. In such cases, it's worth considering new mining equipment with higher efficiency and lower maintenance requirements .
