Qu’est-ce que Whatsminer ?
Whatsminer is the ASIC miner brand manufactured by MicroBT (Shenzhen MicroBT Electronics Technology Co., Ltd.), the world’s second-largest Bitcoin mining hardware manufacturer after Bitmain. Founded in 2016 by Yang Zuoxing — a former Bitmain chip designer — MicroBT has built a reputation for producing miners with excellent build quality, competitive efficiency, and reliable long-term performance.
While Bitmain’s Antminer line dominates market share, Whatsminer has carved out a significant portion of the global hashrate and earned loyalty among miners who appreciate its engineering consistency. MicroBT’s machines are found in industrial mining operations worldwide, and their aftermarket parts and repair ecosystem — while smaller than Antminer’s — continues to grow.
At D-Central Technologies, we have been working with Whatsminer hardware since our earliest days. Our repair facility in Laval, Quebec services Whatsminer units alongside Antminer, Innosilicon, and other brands. We stock Whatsminer miners, carry Whatsminer-specific repair tools, manufacture Whatsminer-compatible shrouds, and publish detailed maintenance and troubleshooting guides for the entire Whatsminer lineup.

Problèmes courants et dépannage Whatsminer
Based on our experience repairing hundreds of Whatsminer units at our Laval, Quebec facility, here are the most common issues we encounter and how to diagnose them.
Défaillances de hashboard
Whatsminer hashboard failures are the most common repair we perform. Symptoms include reduced hashrate (one or more boards showing 0 TH/s), error codes on the dashboard, or the unit failing to detect a board entirely.
Causes courantes :
- Failed ASIC chips — individual chips on the hashboard can fail due to overheating, power surges, or manufacturing defects. Diagnosable with a Whatsminer Hashboard Tester.
- Solder joint degradation — thermal cycling (repeated heat/cool cycles) can crack solder joints over time, especially on BGA connections.
- Power delivery issues — voltage regulator failures or damaged power traces can prevent chips from receiving correct voltage.
- Connector damage — bent pins or corroded connectors between the hashboard and control board.
Dépannage DIY : Check the Whatsminer web interface for error codes. If one board shows 0 TH/s, try reseating the data and power connectors. If the problem persists, the board likely needs professional repair. See our Complete Whatsminer Error Code Reference for specific error diagnosis.
Erreurs de ventilateur et surchauffe
Whatsminer units are sensitive to fan RPM readings. If a fan fails, slows below its minimum threshold, or reports incorrect RPM data, the unit will shut down to protect itself from thermal damage.
Causes courantes :
- Dust accumulation — compressed air cleaning every 3–6 months prevents most fan issues
- Fan motor failure — bearings wear out over time, causing grinding noise then failure
- Cable damage — the fan cable or connector can be damaged during maintenance
- Ambient temperature — operating above 40C ambient will trigger thermal throttling or shutdown
Dépannage DIY : Clean the unit with compressed air. Swap fans between positions to isolate which fan is faulty. Replace failed fans with OEM Whatsminer replacements. Ensure adequate airflow — Whatsminers need at least 30cm of clearance on both intake and exhaust sides.
Problèmes d’alimentation et PSU
Many Whatsminer models (M30 series and newer) have an integrated power supply unit (PSU), unlike Antminers which use an external APW series PSU. This design simplifies the setup but means PSU failures require opening the unit.
Symptômes courants :
- Unit does not power on at all
- Unit powers on briefly then shuts down
- Intermittent power cycling
- Voltage readings outside normal range on the web interface
Important: Whatsminer PSU repairs involve high-voltage components. If you suspect a PSU issue, we strongly recommend professional repair rather than DIY troubleshooting. Incorrect handling can cause serious injury or further damage to the unit.
Problèmes de réseau et de connectivité
Whatsminers connect via Ethernet (no built-in WiFi on most models). Common network issues include:
- No IP address assigned — ensure your router’s DHCP pool has available addresses. Use the Whatsminer tool or check your router’s client list to find the assigned IP.
- Web interface not loading — try a different browser, clear cache, or connect directly via Ethernet without a switch.
- Pool connection failures — verify pool URL, port, and worker credentials. Whatsminer uses stratum protocol — ensure your pool URL starts with
stratum+tcp://. - Firmware update failures — only use official firmware from MicroBT. Failed updates can brick the control board.

Guides de configuration et de micrologiciel
Whether you are setting up a Whatsminer for the first time or updating firmware on an existing unit, these resources will help:
Configuration initiale
- Unbox and inspect — check for shipping damage, verify all fans spin freely, ensure no loose parts inside
- Connect power — Whatsminer M30+ series have integrated PSUs. Connect the C13/C19 power cable directly to a dedicated 220V circuit. The M30S++ draws approximately 3,472 W — ensure your circuit can handle this load safely.
- Connect Ethernet — plug a Cat5e or Cat6 cable into the Ethernet port on the control board side
- Power on and find IP — the miner will request an IP via DHCP. Use the MicroBT IP Reporter tool, check your router’s DHCP client list, or scan your network with a tool like Advanced IP Scanner.
- Access web interface — open the IP address in a browser. Default credentials are typically
admin/admin. - Configure pool settings — enter your mining pool URL, port, and worker name. We recommend adding 3 pool addresses (primary, secondary, tertiary) for failover. See our Mining Pool Comparison for pool recommendations.
- Monitor for 24 hours — watch for stable hashrate, consistent temperatures, and no error codes before considering the setup complete.
Mises à jour du micrologiciel
MicroBT periodically releases firmware updates that improve stability, fix bugs, and sometimes improve performance. Key rules for Whatsminer firmware updates:
- Only use official firmware from MicroBT’s website or authorized distributors. Unofficial firmware can brick your control board.
- Never interrupt a firmware update — power loss during flashing can permanently damage the control board.
- Back up your pool configuration before updating — some firmware updates reset settings to defaults.
- Test after updating — monitor hashrate and temperatures for 24 hours after any firmware change.
Unlike Antminer, Whatsminer has a more limited third-party firmware ecosystem. While Antminer users can install BraiinsOS+, Vnish, or LuxOS for custom tuning profiles, Whatsminer users are largely limited to MicroBT’s official firmware. This is a trade-off: less customization but also less risk of bricking or voiding warranty with unofficial software. For a comparison of Antminer firmware options, see our Firmware Comparison Guide.

Foire aux questions
Whatsminer est-il meilleur qu’Antminer ?
Neither is categorically « better » — they serve different priorities. Whatsminer is known for robust build quality and reliability, making it excellent for set-and-forget industrial deployments. Antminer has a larger aftermarket ecosystem (third-party firmware, accessories, repair parts), making it more flexible for mineurs domestiques who want to customize, silence, or underclock their machines. D-Central carries and repairs both brands. Read our full Whatsminer vs Antminer Comparison for a detailed breakdown.
Puis-je utiliser un Whatsminer comme chaufferette ?
Technically yes — any miner converts all consumed electricity to heat. However, D-Central’s Space Heater Editions are currently built around Antminer platforms because the Antminer form factor is more compatible with our custom enclosure designs. If you want to use a Whatsminer for heating, you can direct its exhaust into your room using a Whatsminer shroud and flexible ducting. The heat output is identical to Antminer at the same wattage — a 3,400 W Whatsminer produces exactly 3,400 watts of heat.
Puis-je faire tourner un Whatsminer en 110V/120V ?
Most full-size Whatsminer models (M30S++, M50 series, M60 series) are designed for 220V–240V operation and cannot safely run on 110V/120V household circuits. The power draw (3,000–3,500 W) exceeds what a standard 120V circuit can provide. If you only have 120V available, consider D-Central’s Antminer Slim Edition or Loki Edition, which are specifically modified for 110V/120V operation, or explore open-source miners that run on standard 5V/12V adapters.
Où trouver des pièces de rechange Whatsminer ?
D-Central stocks Whatsminer-specific tools and diagnostic equipment. For hashboard replacements, chip reballing, and other component-level repairs, our repair service handles the work in-house. Contact us for parts availability and pricing.
Quelle est la durée de vie d’un Whatsminer ?
With proper maintenance (regular cleaning, stable power, adequate ventilation), Whatsminer units typically operate reliably for 3–5 years. The M30 series, now several years old, is still running in many operations worldwide. Build quality is a Whatsminer strength — these machines are engineered for continuous 24/7 operation. Following our maintenance schedule significantly extends operational lifespan.
D-Central répare-t-il les Whatsminer ?
Yes. D-Central’s ASIC repair facility in Laval, Quebec provides comprehensive Whatsminer repair services including hashboard repair, chip replacement, control board diagnostics, PSU repair, and full unit reconditioning.

Quel est le Whatsminer le plus efficace disponible ?
As of early 2026, the Whatsminer M60S++ leads MicroBT’s lineup at approximately 16 J/TH efficiency with 212 TH/s hashrate. This places it between the Antminer S21 (~17.5 J/TH) and S21 Pro (~15 J/TH) in the efficiency rankings. Contact D-Central for current M60 series availability and pricing.
Puis-je installer un firmware personnalisé sur un Whatsminer ?
Unlike Antminer, which supports multiple third-party firmware options (BraiinsOS+, Vnish, LuxOS), Whatsminer has a limited third-party firmware ecosystem. Most Whatsminer operators run MicroBT’s official firmware. While this limits customization (underclocking, custom fan curves, advanced monitoring), it also means fewer opportunities for firmware-related issues. If firmware flexibility is important to you, Antminer platforms offer more options — see our Firmware Comparison Guide.
