Fault Verification Before Repair
We verify reported failures before repair work begins. Miners, hashboards, and PSUs are reviewed by model, symptom, quantity, and test result.
You watch the market. We keep the machines running. We manage maintenance, diagnostics, standard repairs, covered parts coordination, service records, and uptime workflow for commercial ASIC mining farms.
Optimized for commercial mining operations, recurring repair demand, and fleet-scale onsite deployment.
Deployment planning depends on operational scale, recurring failure frequency, infrastructure requirements, and regional dispatch availability.

Complete Miner Pricing Note: Complete miner repair includes up to 3 hashboards inside one miner. PSU repair is not included and is quoted separately at $50–$60 per PSU unit.
Pricing applies to fleet engagements. Final quote confirmed after fault assessment. Contact us to discuss your fleet size, miner model, and facility location.
Pricing shown reflects standard fleet-service rates.
Final dispatch pricing may vary based on facility location, service scope, market conditions, urgency, and equipment volume.
No hidden fees — all pricing adjustments are confirmed before dispatch.
Transparent Repair Process
Every repair engagement is documented with clear fault findings, confirmed repair scope, and service records before final billing.
We verify reported failures before repair work begins. Miners, hashboards, and PSUs are reviewed by model, symptom, quantity, and test result.
Repair scope is confirmed before billing. We document affected units, service category, and whether the issue is hashboard, PSU, control board, fan, thermal, or site-related.
Service records may include repair notes, diagnostic findings, photos, burn-in or load-test results, and replaced component details when applicable.
Final pricing is confirmed before service completion when scope changes. We do not add unexplained charges or bill for unrelated units.
S21 Repair Planning
Many S21-series fleets are still under manufacturer warranty today. We help mining operators prepare for the post-warranty repair window with documented diagnostics, repair-scope review, and batch service planning.
Review miner models, warranty timing, recurring fault patterns, and early failure symptoms before warranty expiration creates paid repair exposure.
Prepare repair paths for hashboards, PSU issues, control boards, fans, and multi-fault units before downtime turns into emergency dispatch.
For high-volume S21 fleets, we help plan batch diagnostics, repair counts, documentation, and repair capacity at scale.
Fleet Operations
Enterprise-level support for mining farms, hosting facilities, and large-scale commercial operators. We service entire fleets in a single engagement — batch diagnostics across all racks, chip-level repair by fault priority, and ongoing preventive maintenance contracts for sustained operational uptime.
Full fleet triage in one visit. Every unit assessed, faults logged by severity. We identify the highest-impact machines first and repair in priority order — not random.
Technician works directly in your server room, shipping container, or hosting facility. No equipment transport required. Rack-by-rack systematic inspection with logged outcomes per unit.
Scheduled visits before failures happen. Fan replacement, thermal compound refresh, connector inspection, firmware verification, and power rail spot-checks across your active fleet.
Sudden mass failure across multiple racks? Power surge recovery, farm-wide hash collapse — we dispatch for large-scale events and prioritize getting the majority of your fleet back online.
Operations Support
Beyond unit-level repair — we support the operational continuity of your mining infrastructure. Rack-level, facility-level, and fleet-level services for active mining operations and hosting facilities.
Audit and balance hash load across racks to optimize efficiency and reduce thermal clustering in high-density deployments.
Identify hotspots, airflow restrictions, and cooling failures before they cause mass shutdowns or accelerated hardware degradation.
Verify PSU output rails under real operating load. Catch under-voltage, ripple, and protection mode conditions before they cause miner failures.
Document fault patterns across your fleet to identify systemic issues — batch firmware problems, power events, or recurring component failures affecting multiple units.
Full fleet triage per visit — every unit logged, prioritized by fault severity, and repaired in structured batch operations to minimize total downtime per engagement.
Scheduled service visits before failures occur. Fan replacement, thermal compound refresh, connector check, and firmware audit across your active fleet.
On-site review of PDU distribution, cable condition, circuit loading, and protection device status — the infrastructure layer below the miners that most repair providers ignore.
Fault Type Reference
Specific fault types diagnosed and repaired onsite at mining facilities. Component-level repair — no board swap.
The S19 XP reports 0 ASIC chips on one or more hashboards, resulting in zero hash output from affected chains. Typically caused by boost circuit failure, ASIC chip damage from a voltage event, or EEPROM addressing error. Diagnosed via CLK/RST signal tracing and voltage section mapping — repaired at component level without board replacement.
WhatsMiner PSUs entering protection mode, producing intermittent output voltage, or shutting down after power events. Often misdiagnosed as a hashboard failure. Root cause is typically MOSFET failure, blown protection fuse, or capacitor degradation on the input stage. Repaired on bench with full load verification.
Avalon miners triggering temperature alarms, throttling hashrate, or shutting down due to reported overheat. Can be caused by fan controller failure, blocked airflow, failed NTC thermistor, or a defective temperature IC. Thermal imaging used onsite to identify hot spots before component-level repair.
One or more hashboards showing 0 GH/s despite being detected by the control board. Indicates a chain-level fault — failed driver IC, BGA pad separation, or a section-level voltage rail collapse. Signal injection used to isolate the exact chain segment before repair.
Fan error reported in the miner UI with one or more fans not spinning or operating at incorrect RPM. Can trigger temperature protection shutdown if unresolved. Caused by fan bearing wear, hall sensor fault, fan controller IC failure, or wiring damage to the fan connector. All fan brands and models serviced onsite.

Common Questions
Emergency dispatch availability depends on technician location, current scheduling, and operational region. For sudden farm-wide failures — mass shutdown or hash collapse after a power event — contact us by phone directly for the fastest response. We prioritize commercial farming emergencies and will give you an honest dispatch timeline immediately.
Onsite field deployment is optimized for commercial-scale repair demand — operations with enough active repair volume, recurring failures, or infrastructure complexity to justify technician travel and full deployment. Mining operations with ongoing repair needs, multi-site maintenance, or growing fleets that regularly generate new failures are well-suited for onsite service. If you're unsure whether your situation qualifies, contact us directly — we'll give you an honest assessment.
Yes. Commercial mining operations with ongoing failure patterns — miners failing regularly as the fleet ages or operates under continuous load — are exactly the type of client we support. Rather than handling each failure separately, we coordinate scheduled service visits, batch repairs across accumulated failures, and long-term maintenance planning to reduce total downtime cost over time.
We service Antminer (S9, S21 series, S19 series, T19, T21), WhatsMiner (M30S, M30S+, M50, M50S, M56, M60, M60S), and Avalon (A1246, A1346, A1366, A1466, A1566). PSU repair covers Bitmain APW7, APW9, APW12, P21, WhatsMiner PSUs, and compatible third-party units.
Yes. We work with commercial operations at different stages — including those building toward larger deployment thresholds or planning multi-site expansion. If your operation is growing or approaching commercial-scale repair demand, contact us to discuss fleet planning, infrastructure readiness, and service options aligned to your operational timeline.
