Frequently Asked Questions

We repair MicroBT Whatsminer (in-warranty and out-of-warranty) and Bitmain Antminer hardware. For MicroBT, we are an authorized North American warranty service center.

Yes — PSU repair is a standard part of the service, not an add-on. We diagnose and repair air-cooled, immersion and hydro power supplies for Whatsminer and Antminer at component level and load-test them before return. You can send PSUs on their own or with the machine, and a working spare PSU is often worth more to you than a scrapped one.

We prefer new components and use them whenever available. For parts that are out of production or in limited supply, refurbished components may be the only viable option — in those cases we source the best quality available and stand behind the repair with the same 30-day guarantee.

Turnaround varies — some repairs are completed same day, while others take longer depending on complexity and current volume. The ASIC repair market is cyclical, and during volatile periods incoming volume can spike significantly, making it difficult to predict lead times in advance. We always recommend reaching out at the time of your order so we can give you the most accurate expectation based on current conditions.

If any issue related to the repair arises within 30 days of delivery, we'll fix it at no additional charge. The guarantee covers the specific repair we performed — not unrelated failures or physical damage incurred afterward. This is our own guarantee on our workmanship, and is separate from any manufacturer warranty on the equipment itself.

Contact us to initiate a repair request. We'll provide shipping instructions, our facility address in Chicago, and guidance on packaging. We also offer logistics coordination if you need help moving large quantities of machines.

Yes — our field service team can travel to your data center for on-site diagnostics, deployments, and repairs. Contact us to discuss your situation and we'll determine the best approach.

Our 5-part bootcamp covers Introduction to ASIC mining, Intermediate diagnostics, Advanced diagnostics, Advanced repair & soldering, and Hydro/Immersion cooling. It's backed by a 400+ page proprietary guidebook.

The standard format is 1 week for technicians focused on site operations and repair. A 2-week format is available for those who will also be performing board-level soldering and component rework.

Parts 1 and 2 of the curriculum are available virtually. Parts 3–5 require in-person attendance at our Chicago facility due to the hands-on nature of the diagnostics, soldering, and immersion cooling modules.

Yes. Students typically repair 10–30 machines during the training program. The hands-on volume varies by individual pace and the complexity of machines encountered.

The program is designed for a wide audience — technicians, site managers, business owners, investors, and data center staff. No prior technical experience is required, though it is beneficial.

We provide site selection, facility build-out guidance, vendor selection, infrastructure equipment sourcing, and site inspection & audit services. We draw on direct operational experience managing mining facilities.

Our 50,000 sq ft Chicago facility handles receiving, processing, storage, and staging of mining equipment at scale. We have direct access to major rail lines and expressways, and expertise in packaging time-sensitive, high-value cargo.

Yes. Whether you're upgrading to newer hardware or fully liquidating, we leverage our network of active buyers to move your equipment quickly and at fair market value.

Yes. We source machines across all major manufacturers — MicroBT, Bitmain, and others. Our relationships give you access to inventory that isn't always publicly available.
