ASIC Excavator Service and Repair – Professional Diagnostics and Repair of Equipment

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.

ASIC’s 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.

Why do ASIC miners fail?

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.

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.

The Most Common Problems with ASIC Excavators

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.

• Hashboard not detected – the system sees fewer boards than it should, or does not detect any.
• Low or unstable hashrate – the device does not meet the manufacturer’s specifications or periodically loses power.
• ASIC chip errors – some chips fail to respond, report errors, or overheat.
• Restarting the machine – the excavator shuts down and restarts under load.
• Temperatures are too high —the fans are running at maximum speed, and the device is limiting its power output.
• Power supply failure – no power, unstable voltage, overheating, or unusual noises.
• Firmware issues —unable to access the control panel, startup errors, or a failed update.
• Damage caused by flooding or power surges —corrosion, short circuits, burnt components, or damaged circuit traces.

What does a professional diagnostic check of an ASIC excavator involve?

A thorough repair should always begin with a complete diagnostic check. The error message displayed on the device’s 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.

Repair of hashboards and electronics

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.

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.

When does it make sense to repair a hashboard?

The decision depends on the value of the device, the availability of parts, the extent of the damage, and the cost of a new motherboard. For newer models, repairing the electronics is often the most sensible solution. However, in cases of extensive damage, a technician may recommend replacing the component.

ASIC Miner Cooling: AIR, HYDRO, or IMMERSION?

An efficient cooling system has a direct impact on the device’s stability, performance, and service life. Excessively high temperatures can cause chip errors, power throttling, reboots, and permanent damage to the electronics.

Air-Cooled System Service

For standard AIR excavators, it is essential to regularly clean the heat sinks, air ducts, and fans. Worn-out fans should be replaced, and the condition of the thermal paste and thermal pads should be checked.

Conversion from AIR to HYDRO

Converting an excavator from air cooling to water cooling can reduce noise and improve thermal conditions. However, such a modification requires properly selected cooling blocks, a fluid circulation system, leak testing, and proper configuration of the equipment.

Preparing for Immersion Cooling

In an immersion system, the device operates while submerged in a special dielectric fluid. Before installation, the excavator must be properly prepared, any components not suitable for immersion must be removed, and the compatibility of the materials with the fluid being used must be verified.

Firmware, Configuration, and Performance Optimization

Not every malfunction is caused by electronic damage. Problems can also be caused by incorrect configuration, corrupted firmware, incorrect network settings, or a failed update.

• firmware updates and restores,
• configuration of pools and mining parameters,
• resetting the device and clearing system errors,
• Restoring devices after a failed flash or soft brick,
• selecting settings based on operating conditions and energy costs.

Overclocking ASIC Miners

Overclocking allows you to increase a device’s hashrate, but it usually also leads to higher power consumption and temperatures. Settings should be adjusted on a case-by-case basis, taking into account the device’s technical condition, power supply, and cooling performance.

Downclocking and Improving Efficiency

Downclocking involves reducing a device’s power to lower energy consumption, temperature, and noise. Depending on the model and the cost of electricity, it can improve performance and reduce the load on components.

What types of ASIC miners do we service?

Our service covers devices from the most popular manufacturers. Whether we can repair a specific model depends on the availability of parts, technical documentation, and the nature of the malfunction.

We service, among others, devices from the popular Antminer S19, S21, L9, KA3, Z15, and AL1 series, as well as select WhatsMiner models and devices from other manufacturers. For less common devices, repair options are determined on a case-by-case basis.
