Our Process
How the Repair Process Works
A straightforward, four-step process designed to get your miners back online as fast as possible.
Submit a Service Request
Fill out our service form with your fleet size, miner models, and location. We'll confirm availability and schedule a visit within 1 business day.
On-Site Diagnostics
Our senior technicians arrive on-site with full diagnostic gear. Each unit undergoes chip-level hashboard inspection, power rail testing, and fault isolation.
Chip-Level Repair
We replace failed ASIC chips, MOSFETs, and capacitors using professional reflow stations and original-spec parts. Every repair includes a burn-in validation test.
Back Online with Documentation
Your miners return to full operation. You receive a detailed repair report for each unit, warranty, and continued support through our ticket portal.
Supported Models & Repair Expertise
Chip-level repair services for the most demanding Bitmain ASIC miners — performed on-site or via mail-in.
Antminer Z15 / Z15J
The Z15 and Z15J hashboards are built around the BM1746 ASIC chip operating under demanding Equihash workloads. Our technicians perform precision MOSFET replacement on the power delivery rails, core-voltage short-circuit diagnosis using thermal imaging, and professional reflow/reballing of failed Black Rhino chips. Each repaired board goes through full hashrate burn-in testing before return.
- BM1746 chip replacement
- Core voltage short-circuit diagnosis
- MOSFET replacement on power rails
- Thermal management & paste refresh
- 24-hour burn-in stability test
Antminer Z15 Pro
The newer Z15 Pro pushes more hashrate and runs noticeably hotter than the original Z15, so heat drives most of its failures. We fix the four issues Z15 Pro owners see most: overheating and thermal throttling, "Temp NG" / 0°C temperature-sensor errors, hashrate drop from dropped-out chips, and "cannot find hashboard" faults caused by a broken serial chain or dead core-voltage rail — all repaired at the chip level with genuine parts.
- Thermal interface refresh & cooling repair
- Temperature-sensor fault repair
- Hashrate-drop / missing-chip recovery
- Board-not-detected chain repair
- 24-hour full-load burn-in test
Antminer Z11
The Z11 is an older Equihash miner with three BM1744 ASIC chips wired in a serial chain per hashboard, so a single dead chip or cracked solder joint drops the whole board to 0 hashrate. We revive aging Z11 boards — tracing broken chains, clearing core-voltage shorts, repairing worn power components, and replacing failed chips with genuine parts — a cost-effective way to keep older fleets earning instead of scrapping them.
- BM1744 chip replacement
- 0-hashrate / broken serial-chain repair
- Core voltage short-circuit fix
- Aging solder & power-component repair
- 24-hour burn-in stability test
Antminer S21 Pro / S21 XP
The S21 Pro and S21 XP run on Bitmain's 4nm BM1370 / BM1368 ASIC chips and are known for high power density, which demands precision thermal management to sustain peak efficiency. We specialize in domain-voltage short diagnostics, chip replacement using professional reflow stations, and PIC/EEPROM communication fault resolution. Common issues like "missing boards" and "SOC init failed" errors are fully addressed at the chip level.
- BM1370 / BM1368 chip reflow & replacement
- Domain voltage short diagnosis
- PIC / EEPROM communication repair
- High-density thermal interface refresh
- Hashrate stability tuning
Antminer L9
The L9 is Bitmain's flagship Scrypt (Litecoin/Dogecoin) miner and runs extremely hot, making its hashboards prone to chip failures and power-rail faults. We handle Scrypt ASIC chip replacement, core-voltage short-circuit diagnosis, MOSFET and buck-converter repair, and resolve "missing hashboard" and low-hashrate errors. Every L9 board is burn-in tested at full load before return.
- Scrypt ASIC chip replacement
- Core voltage short-circuit diagnosis
- MOSFET & buck-converter repair
- Thermal management & paste refresh
- 24-hour full-load burn-in test
Antminer PSU
The Miner on the APW12 or APW17 power supply — high-density units that require expert component-level care. We repair blown MOSFETs and rectifier diodes using original-spec parts, resolve PIC chip and voltage regulation failures on the control board, perform Power Factor Correction (PFC) circuit diagnostics with full capacitor bank overhauls, and restore units damaged by surge events such as grid instability or phase imbalances.
- MOSFET & rectifier replacement
- Chip repair
- PFC circuit diagnostics & capacitor overhaul
- Surge & grid-damage recovery
- Full-load 24-hour burn-in test

Common Questions
We handle all levels — from fan and PSU replacement to full chip-level hashboard repair. Our technicians arrive with professional reflow stations, thermal imaging equipment, and original-spec components to perform the same repairs on-site that would otherwise require a service depot.
We specialize in Bitmain Antminer models: S19 series, S21, T21, S21 Pro, S21 XP, Z15, L7, and L9 — as well as APW12/APW17 PSUs. We also service Whatsminer and Iceriver units. Contact us if your model isn't listed.
Shipping miners across state lines is expensive, slow, and carries real risk of transit damage. Our on-site fleet eliminates all of that — we come to your farm, diagnose and repair in place, and get units back online the same day. You stay in control throughout.
We charge per completed repair — no fixed contracts, no retainers, no minimum commitments. You only pay for units we successfully fix. Each repaired device comes with parts and labor warranty.
We accept credit cards, ACH/bank transfer
Yes. Volume pricing is available for fleets with 300+ units. Contact our team to discuss rates based on your fleet size, miner models, and repair scope.
For every scrapped hashboard or PSU, we provide a detailed report with documented fault evidence and photos. With your consent, salvageable components may be repurposed as repair parts for other units — we never discard usable hardware without authorization.
