\n ASIC miners operate around the clock, often under heavy loads and in demanding conditions. High temperatures, dust, fan wear, power supply issues, or software errors can lead to reduced performance, unstable operation, or even a complete shutdown of the device. \n <\/p>\n\n

\n ASIC\u2019s professional excavator service allows you to quickly pinpoint the cause of a malfunction, minimize equipment downtime, and restore the machine to full operational capacity. In this guide, we explain which faults occur most frequently, how diagnostics are performed, and when it makes economic sense to repair a hashboard, power supply, or cooling system. \n <\/p>\n\n

    Why do ASIC miners fail?<\/h2>\n\n

    \n An ASIC miner is a device designed to continuously perform a very large number of calculations. Unlike a regular computer, it typically operates nonstop, 24 hours a day, 7 days a week. This means constant strain on the chips, power supply components, fans, and the power supply unit. \n <\/p>\n\n

    \n Temperature is the biggest enemy of electronics. If a device is operating in a dusty room, has limited airflow, or has malfunctioning fans, heat is not properly dissipated. This leads to instability, chip errors, a drop in hashrate, and accelerated wear and tear on components. \n <\/p>\n\n

    The Most Common Problems with ASIC Excavators<\/h2>\n\n

    \n Symptoms of a malfunction can vary widely. Sometimes the miner starts up but achieves too low a hashrate. In other cases, the device fails to detect one of the boards, overheats, restarts, or does not respond at all when powered on. \n <\/p>\n\n

      \n
    • Hashboard not detected<\/strong> \u2013 the system sees fewer boards than it should, or does not detect any.<\/li>\n
    • Low or unstable hashrate<\/strong> \u2013 the device does not meet the manufacturer’s specifications or periodically loses power.<\/li>\n
    • ASIC chip errors<\/strong> \u2013 some chips fail to respond, report errors, or overheat.<\/li>\n
    • Restarting the machine<\/strong> \u2013 the excavator shuts down and restarts under load.<\/li>\n
    • Temperatures are too high<\/strong> \u2014the fans are running at maximum speed, and the device is limiting its power output.<\/li>\n
    • Power supply failure<\/strong> \u2013 no power, unstable voltage, overheating, or unusual noises.<\/li>\n
    • Firmware issues<\/strong> \u2014unable to access the control panel, startup errors, or a failed update.<\/li>\n
    • Damage caused by flooding or power surges<\/strong> \u2014corrosion, short circuits, burnt components, or damaged circuit traces.<\/li>\n <\/ul>\n\n
      \n Important<\/strong>\n Continuing to operate the machine with a malfunctioning cooling system, power supply, or chip errors may cause further damage. It is advisable to shut down the excavator and have it inspected before additional components are damaged. \n <\/div>\n\n \n

      What does a professional diagnostic check of an ASIC excavator involve?<\/h2>\n\n

      \n A thorough repair should always begin with a complete diagnostic check. The error message displayed on the device\u2019s panel does not always indicate the actual cause of the malfunction. A problem with the hashboard may result from, among other things, damage to the chip, communication line, power supply, temperature sensor, controller, or power supply unit. \n <\/p>\n\n

      Repair of hashboards and electronics<\/h2>\n\n

      \n The hashboard is one of the most important and heavily loaded components of an ASIC miner. It is where the specialized chips responsible for performing calculations are located. Damage to a single chip, power supply component, or communication line can cause the entire chip chain to shut down or result in the board not being detected. \n <\/p>\n\n

      \n Professional hashboard repair isn’t just about replacing the entire board. In many cases, it’s possible to locate and fix the problem at the component level, which can be much more cost-effective than buying a new board. \n <\/p>\n\n
